How is the characterization of computer cable introduced?

I. How is the introduction of the characteristics of computer cable? Computer cables are cables used for electrical equipment, which are suitable for electronic computers and automation instruments with rated voltages of 500V and below that require high immunity to interference. According to the requirements of different environments and equipment, the cable insulation can be made of polyethylene, PVC, cross-linked polyethylene, fluoroplastic, silicone rubber and other materials. Computer cable precautions:1. Computer cable overload. This should be tried in most cases, if the load is too large, it is considered no problem, you can buy a small wire and cable model in advance.2. Computer cables should be avoided as much as possible from direct sunlight and man-made damage, it is recommended to use a safer conduit.3. Cables are laid directly in the cable trench, the range of control is relatively small, regularly check the cable trench installation is not humid, moisture on the cable is a huge destructive factor and a great safety risk.4. Even if cables are routed through conduits, the conduit data should be considered. Since metal pipes produce high temperatures in the hot sun, they can also cause great damage to cables. Characteristics of computer cable: 1. Insulation should be selected with antioxidant function and low density of PE. PE insulation material has high resistance, good voltage resistance, dielectric coefficient and dielectric loss is small, and the effect of temperature and frequency change a very small. Both to get to meet the functional requirements of the information transmission system, but also to ensure that the service life of the computer line.　　2, computer cable installation and laying temperature shall not be lower than 0 ℃.　　3, computer cable allowable bending radius: non-armored cable is very small, 6 times the outer diameter of the cable.
