Video cable refers to the cable that transmits video signals (VIDEOs) and can be used for signal transmission in monitoring systems.     General model: SYV75-X (X represents its insulation outer diameter of 3mm/5mm, the larger the number, the thicker the wire diameter) SYV S-coaxial RF cable, Y-polyethylene, V-polyvinyl chloride 75 represents the characteristic impedance, and the video cable is divided into 75-3 (100 meters) for normal working transmission distance, 75-5 (300 meters) for normal working transmission distance, 75-7 (500-800 meters) for normal working transmission distance, and 75-9 (1000-1500 meters) for normal working transmission distance. The commonly used model is SYV75-5, and the same manufacturer may also provide products at different prices. The specific difference is whether the copper used is pure copper or copper-clad aluminum, or the number of twisted copper cores in the outer shielding layer, such as 96 braided (referring to 96 thin copper cores woven), 128 braided, etc. The more braided, the better the shielding performance. Therefore, this should be noted when purchasing products.

Drag chain cable, also known as drag cable or tank chain cable. Its basic definition is to prevent cable entanglement, wear, pulling off, hanging, and scattering. Cables are often placed in cable drag chains to protect them, and they can also move back and forth with the drag chains. This type of high flexibility specialized cable can move back and forth with the drag chains without being easily worn out.     The structure of the drag chain cable is:     1. Tensile center   As much as possible, there should be a true centerline filling in the center of the cable based on the number of cores and the space where each core wire intersects (instead of using some filling materials or waste plastic made garbage core wires as usual). This method can effectively protect the stranded wire structure and prevent the stranded wire from floating to the center area of the cable.     2. Conductor structure   Cables should choose the most flexible conductor. Generally speaking, the thinner the conductor, the better the flexibility of the cable. However, if the conductor is too thin, it can cause cable entanglement. A series of long-term experiments have provided the optimal diameter, length, and nodal shielding combination for a single wire, which has the best tensile strength.     3. Core wire insulation   The insulation materials inside the cable cannot stick to each other. And the insulation layer also needs to support each single strand of wire. Therefore, its reliability can only be confirmed in the application process of PVC or TPE materials formed under high pressure for millions of meters of cables in drag chains.     4. Twisted wire   The stranded wire structure must be wound around a stable tensile center at the optimal intersection pitch. However, due to the application of insulation materials, the stranded wire structure should be designed according to the motion state, starting from 12 core wires, and therefore should be twisted into bundles.     5. Filler or accessory filler   The inner sheath of the armor is extruded to replace cheap wool materials, fillers or accessory fillers. This method can ensure that the stranded wire structure will not be scattered.     6. Braided shielding   The tightly woven inner sheath and loose woven tape will reduce the EMC protection ability, and the shielding layer will quickly fail due to the breakage of the shielding. The tightly woven shielding layer also has the function of resisting torsion.     7. High performance outer sheath   The outer sheath made of different improved materials has different functions, including UV resistance, low temperature resistance, oil resistance, and cost optimization. But all of these outer sheaths have one thing in common, high wear resistance and will not adhere to anything. The outer sheath must be highly flexible but also have a supporting function, of course, it should be high-pressure formed.  

The quality of wire harness materials directly affects the quality of the wire harness, and the choice of wire harness materials is related to the quality and service life of the wire harness. Reminder to all merchants, when choosing wire harness products, they must not be tempted by cheapness. Cheap wire harness products may use inferior wire harness materials. How to distinguish the quality of the wiring harness? Once you understand the material of the wiring harness, you will understand. The following is the information on wire harness material selection.     A wiring harness is generally composed of wires, insulation sheaths, terminal blocks, and wrapping materials. As long as you understand these materials, you can easily distinguish the quality of the wiring harness.   1、 Material selection for wiring terminals   The copper used for terminal materials (copper parts) is mainly brass and bronze (brass has slightly lower hardness than bronze), with brass accounting for a larger proportion. In addition, different coatings can be selected according to different needs.   2、 Selection of insulation sheath   The commonly used materials for sheath materials (plastic parts) include PA6, PA66, ABS, PBT, PP, etc. Flame retardant or reinforcing materials can be added to plastics according to the actual situation to achieve the purpose of reinforcement or flame retardancy, such as adding glass fiber reinforcement.     3、 Selection of wiring harness wires   Choose the appropriate wire material according to the different usage environments.   4、 Selection of bandaging materials   Wire harness wrapping plays a role in wear resistance, flame retardancy, corrosion prevention, interference prevention, noise reduction, and appearance beautification. Generally, the wrapping material is selected according to the working environment and space size. In the selection of wrapping materials, there are usually tape, corrugated pipe, PVC pipe, etc.

The main physical method for quickly distinguishing between standard high-temperature lines and non elevation temperature lines is: 1. Weigh, 2. Rub, and 3. Look. The specific operation is as follows:     1. Weighing   Good quality UL electronic wires are generally within the specified weight range. The commonly used PVC insulated multi stranded copper core wire with a cross-sectional area of 0.35 weighs 3.5-3.6kg per roll; 0.85 PVC insulated multi strand copper core wire, with a weight of 5.3-5.40kg per roll. Poor quality wires have insufficient weight, either insufficient length, excessive impurities in the copper core of the wire, and many wires have hollow cells in the PVC layer of the outer layer, resulting in uneven texture.     2. Distinguish copper material   The qualified copper core UL electronic connector wire should have a purple red color, luster, and soft touch. However, fake and inferior copper core wires have purple black, yellowish or white cores, high impurities, poor mechanical strength, poor toughness, and can break with a little force. Moreover, there are often broken wires inside the wires. When checking, you just need to peel off one end of the wire by 2cm, and then rub a piece of white paper slightly on the copper core. If there is black substance on the white paper, it indicates that there are more impurities in the copper core. In addition, the insulation layer of fake and inferior wires may seem thick, but in reality, most of them are made of recycled plastic. Over time, the insulation layer will age and leak electricity.     3. Look at the manufacturer   Counterfeit and inferior UL electronic wires are often "three no products", but they also have ambiguous origin and other markings on them, such as "Made in China" or "Made in a certain province or city in China", which is actually equivalent to unmarked origin. And the outer packaging of the wire does not have a UL blue label specially issued by UL company.

When wholesaling power cables and wires, we cannot just look at the price, we must consider the quality and quantity of production. Nowadays, almost all power cable systems are installed through walls and other means. If the quality of the wires is poor, it will definitely affect their long-term use. If we want to make a large-scale acquisition, we must consider cost-effectiveness, so comparisons in terms of quality and price are essential.     How to compare the quality of electronic wires and high-temperature wires?   Investigate the appearance. Since we want to purchase high-quality power cable products, we must still pay attention to their specific appearance, and item comparison is also important. It is necessary to check whether the outer plastic skin has glossiness, whether the color is uniform, and whether the position of the insulator must be high-quality and fine. Silicone wire can be ignited with a lighter, and if there is no open flame, its quality is still good.   Investigate the cross-section. We can investigate the cross-section of the wire. High quality power cable products are generally made of copper, which has a bright outer layer and a certain degree of flexibility, visible to the naked eye for its quality and brightness. If it is not a legitimate product, the copper will show some blackening, and the resistance of mixed copper wires will be relatively high, and the conductivity will also be poor, which is not safe enough. So we still need to pay special attention to the inspection of the cross-section to avoid affecting the subsequent use.   Measurement of power cable components. If you want to ensure that the purchased home wires are of high quality, then it is still necessary to measure the weight properly. High quality copper cores have certain specifications for their own weight, so it is necessary to have a clear understanding of the weight distribution. This ensures the acquisition of suitable home decoration wire products, and the subsequent use will not be affected.  

Knowing these points is enough to judge the quality of cables. Nowadays, there are various brands of wires and cables on the market, and the quality of electronic wires is indeed uneven. However, once these products are installed and used, they will be used for a long time. Electronic wires are often buried in the device, and once a fault occurs, it is indeed difficult to handle. In fact, to purchase high-quality electronic cables, one only needs to compare them from the following aspects. To determine whether there is certification, cables produced by legitimate manufacturers now require multiple inspections. In addition to self testing by the manufacturer, they also need to undergo relevant inspections. Therefore, before purchasing a product, it is important to pay attention to whether it has quality system certification and a standardized certificate of conformity.     The packaging of Ethernet cables must include relevant information from the manufacturer, such as inspection stamps, production dates, specifications, etc. It is already necessary to acquire information such as wires, and ensuring quality certification is also crucial. Comparing items is crucial, especially since many projects require large-scale use of wires before we see them. Therefore, before purchasing, we must do a good job of basic item comparison. On the one hand, its raw materials require a certain degree of softness and must ensure fatigue strength. Especially on the insulation of the wire, there should be no cracks, and it is necessary to ensure smoothness and a certain thickness. It is important to pay attention to the cross-section of the copper core of the cable and determine its quality in order to facilitate future use.   Pay attention to weight testing. The quality of the copper core used in high-quality silicone wire is clearly defined and must reach a certain weight to ensure its quality. So we still need to pay attention to the measurement of COFCO, as poor quality products generally lack COFCO. We can directly take something for measurement, so that we can determine the specific quality of the wire and facilitate our comparison of production quality. The choice of manufacturer is very important because many projects use a large number of cables, so it is best to directly cooperate with rubber coated wire manufacturers, so that wholesale purchases are also guaranteed. High temperature cables from legitimate manufacturers will have clear product labeling and provide good after-sales service. As long as the manufacturer's production capacity is guaranteed, the natural wholesale purchase price is also guaranteed.

Almost every household is using Ethernet cables, and even with the increasing use of wireless systems, the basic connectivity of Ethernet cables cannot be neglected. Moreover, this type of communication cable product must be used for decoration, and many power cable projects also need to use this type of communication cable product in bulk. So if you want to purchase wholesale, you must first pay attention to quality, and then measure the price, so that you can choose products with high cost-effectiveness. So how to determine the production quality in detail? Pay attention to the labeling status. Currently, the labeling for Category 3 cables is CAT3, but only 10M bandwidth can be used, which has basically been phased out in most cities. And Category 5 cable is the identifier of CAT5, with a bandwidth of 100M. If the bandwidth we use in daily life is within 100Mbps, then we can use CAT5 Ethernet cables. But if it is a higher bandwidth, then you need to choose CAT5E or CAT6 products, which can be used for gigabit networks, ensuring stability and transmission speed. Attention should be paid to the recognition of physical objects. Most Ethernet cables are used for a long time, and if we want to ensure their effectiveness, we cannot neglect the quality of the materials. Generally, there are four pairs of eight wires inside the five types of wires, and their quality can be determined directly by looking at the cross-section. And better network cable outer rubber is not easy to burn and has good insulation performance. Poor quality outer rubber is relatively easy to burn.     High quality Ethernet cables will not deform or soften even when used in high temperatures above 40 ° C. Moreover, the copper core material inside the high-quality network cable itself is quite good, with a certain degree of toughness and softness, but it is not easy to be pulled apart. Communication cables have different numbers of turns in cross-section, and if the number of turns is the same, it may cause signal interference. Therefore, when choosing, it is also important to pay attention to the comparison of the foundation. Although many businesses need to purchase Ethernet cables in bulk, only by clearly defining their quality can they measure the price situation. Nowadays, many businesses can provide online wholesale services, and measuring prices is relatively simple. As long as we cooperate with legitimate manufacturers, it is easy to choose products with high cost-effectiveness.

Precautions for laying and installing pre branched cables   Pre branch cable is a type of cable that is prefabricated by the factory during the production of the main cable according to the customer's design drawings. It is a new technological product in recent years. Compared with the original technology, it has excellent seismic resistance, air tightness, and water resistance. Pre branch cables are cables made by factories to prefabricate branch lines based on customer design drawings during the production of main cables. It is a new technology product in recent years, and the branch line factory pre manufactures it on the main cable. The size of the branch line section and the length of the branch line are determined according to design requirements, which greatly shortens the construction period, greatly reduces material and construction costs, and ensures the reliability of power distribution.   Pre branch cables are cables produced directly from the main and branch lines of cable factories after on-site measurement. No need to bring it to the site for branch joints, greatly saving project time and costs.   When a relay cable requires branching, branch cables can be used, especially in high-rise buildings. If ordinary cables are used without branch cables, a cable from the bottom to the top of the building needs to be decorated as the main line. In order to connect each floor of the distribution box, branch circuits are required. During on-site construction, it is necessary to connect branches on the main line. Laying branch cables on site is not only time-consuming and labor-intensive, but also has lower joint quality. Branch cables are prepared in advance in the factory, reducing the workload on the construction site and ensuring the quality of joints.   (1) Try to use front suspension when laying. When the construction site is limited or there are special requirements, reverse hoisting can also be used. Regardless of the setting, it is not allowed to release the branch line in advance in the process to prevent scratches when the branch body passes through the hole, and to avoid excessive mechanical external forces.   (2) When hoisting, it is necessary to use ropes with a cable weight of more than 4 times. After laying, the fixing fixtures should be installed from top to bottom first.   (3) The bending radius of the cable during laying and installation shall not be less than 25D.   (4) When fixing single core prefabricated branch cables, the use of metal clamps is prohibited.   (5) When connecting electrical measuring and measuring instruments to main and branch lines, it is necessary to use metal wire clamps and correctly select the metal type of the wire clamp.   Pre branch cables are mainly used for distribution relays in high-rise buildings. The main cable conductor has no joints (the joints are processed and enclosed at the branch points when leaving the factory), and the distribution of branch cables is similar to that of bus ducts. However, the cable has good seismic, sealing, and waterproof performance, occupies a small area, and is easy to install. The disadvantage is that quality faults need to be repaired on site, and the conditions are not interchangeable for specific engineering and cable processing. For example, a building has 24 distribution floors, each with a branch. The main line is divided into 3 lines (each line has 8 distribution layers and a current of 315A). Each layer has one cable with a current of 40A. 2. Specification of relay cable YJV-4 * 185+1 * 95. Specification of branch cable YJV-5 * 16. Separation length of 2m; 3. The standard floor height is 3m, and the length from the distribution room to the first floor is 80m; 4. (feeder cable 3 * 80m), finished pre branched cable 3 * 25m, support spacing of 3m, and 3 cable transition boxes.

The difference between low smoke and halogen-free cables and ordinary cables   A high-voltage line is a single component that connects two devices to transmit electrical signals, formed by connecting, twisting, or weaving two or more wires together. This high-voltage line has a wide range of applications and needs to be customized for various purposes. Its function is as large as that of wire products, used for transmitting electrical energy, electrical signals, and achieving electromagnetic energy conversion. High voltage power lines are usually composed of high-voltage wire cores used for transmitting electricity or electrical signals, and cover cotton used for protection and insulation. High voltage wires with only one core and smaller diameter are commonly referred to as wires. Some wires are also known as bare wires without insulation cover cotton. The high-voltage wire core in high-voltage lines is made of metal materials with good conductivity, usually copper (good conductivity) or aluminum (low cost). Low smoke and halogen-free cables refer to those made from non halogen (F Cl、Br、I、At)、 Environmentally friendly high-voltage lines made of rubber containing environmental substances such as lead, cadmium, chromium, and mercury will not produce toxic smoke at high temperatures. The prime pointer is designed according to the specified standards, with all prime values ≤ 50PPM and the hydrogen evolution air pressure content generated after high temperature<100PPM. Once a fire occurs, it may be burned down and unable to operate, but it can prevent the spread of the fire. Generally speaking, in the event of a fire on a high-voltage line, it can limit the high temperature to a local range without spreading, protecting other equipment and avoiding greater losses. According to the different flame-retardant materials of high-voltage lines, flame-retardant high-voltage lines are divided into those containing flame-retardant high-voltage lines and those without low smoke flame-retardant high-voltage lines.   What is a low smoke halogen-free cable? As the name suggests, low smoke refers to reducing the production of harmful substances during high-temperature processes; Su is a toxic air pressure that is harmful to the human body. Without Su, it means that toxic air pressure will not be released, usually in the event of a fire on a high-voltage line. Low smoke and no power high-voltage lines can also be referred to as environmentally friendly high-voltage lines. Low smoke and flame-retardant high-voltage wires are commonly used in hospitals and places with strict environmental hygiene requirements.   The insulation layer, cover cotton, outer cover cotton, and auxiliary materials (tape and filler) of low smoke halogen-free cables are entirely or partially made of flame-retardant materials containing polyethylene (PVC), thus having good flame retardant performance. However, high temperatures in high-voltage lines can release a large amount of smoke and acid air pressure. Acid air pressure can cause corrosive damage to surrounding electrical equipment. Rescue personnel need to wear gas masks to approach the scene and extinguish the fire.   When the high-voltage line is at high temperature, it can cause harm to the surrounding electrical equipment and rescue personnel, which is not conducive to firefighting and rescue work, thus causing serious secondary hazards. However, the insulation layer, cover cotton, outer cover cotton, and auxiliary materials (tape and filler) of low smoke and no cables are entirely or partially made of cross-linked polyethylene (XLPE) flame retardant materials, which not only have better flame retardancy, but also have no acid and air pressure emissions at high temperatures in high-voltage lines. The smoke emissions from high-voltage lines are also very small, and the smoke emissions are close to the recognized "low smoke" level.

The shielding layer can effectively shield external electromagnetic interference and ensure stable signal transmission. Moreover, the sheath layer is made of wear-resistant, bending resistant, and oil resistant materials, which can protect the cable from external mechanical damage and chemical corrosion.   The performance characteristics of servo cables are very prominent. It has high flexibility and can adapt to various complex motion trajectories and installation environments. At the same time, it also has excellent wear resistance and bending resistance, and can maintain stable performance even under frequent bending and friction. In addition, servo cables also have excellent anti-interference ability, which can effectively resist the impact of external electromagnetic interference on signal transmission.   In the field of industrial automation, servo cables are widely used. Whether it's machine tools, robots, or production lines, they all rely on the support of servo cables. It connects servo motors and servo drives to achieve precise position control, speed control, and force control, providing powerful power for industrial automation. However, the selection and use of servo cables also require attention to some issues. Firstly, it is necessary to select the appropriate cable model and specification based on the specific servo motor and driver to ensure the performance and stability of the cable. Secondly, during installation and use, it is important to avoid excessive stretching, bending, and compression of the cable to prevent damage. In addition, it is necessary to regularly inspect and maintain the cables to ensure they are in good working condition.   In summary, servo cables, as an important component of industrial automation, provide strong guarantees for the stable operation of servo systems with their unique structure and performance characteristics. With the continuous development of industrial automation, the application of servo cables will also become more and more widespread, and their role in the field of industrial automation will become increasingly important.
