Computer cable use; Suitable for power generation, metallurgy, petrochemical and other industrial and mining enterprises distributed system, electronic computer system, automation system signal transmission and testing instruments, instruments and other connections with multiple pairs of shield cables.

Computer cable conductor adopts tinned wire or oxygen free bare copper wire, J-edge polyethylene and polyvinyl chloride, shielding is divided into braided shield copper tape winding shield aluminum tape winding shield, good anti-interference effect. Usage characteristics: The operating temperature generally does not exceed 70℃. The height of the rear belt 105 does not exceed 105℃. Low ambient temperature: -40 ° C for fixed installation -15 ° C for non-fixed installation Rated voltage below 500V.

This product is suitable for the rated voltage of 500V and below for the high requirements of anti-interference electronic computer and automatic connection cable. Cable ground wire core J

The edge is made of K-type B-type polyvinyl with antioxidant properties. The J-edge of polyethylene has high resistance, good voltage resistance, small dielectric coefficient and small influence of dielectric loss temperature and variable frequency. It can not only meet the requirements of transmission performance, but also ensure the service life of the cable. 1

In order to reduce cross-talk and external interference between circuits, the cable adopts shielding structure. The shielding requirements of cables are based on different occasions: combined shield, combined shield of cables, combined shield after combined shield and so on.

Shielding material has round copper wire, copper belt, aluminum belt/plastic composite belt three. The shielding pair and the shielding pair have better J-edge performance, and the transmission quality of the signal will not be affected if there is potential difference between the shielding pair in use.
