Computer cable use; suitable for multi-pair shielded cables for power generation, metallurgy, petrochemical and other industrial and mining enterprise distribution systems, electronic computer systems, automation systems, signal transmission and connection of testing instruments, meters, etc.

Computer cable conductors are made of tinned wire or oxygen-free bare copper wire, J-edge polyethylene and polyvinyl chloride. Use characteristics: The working temperature generally does not exceed 70 °C, and the height of the belt 105 after the model does not exceed 105 °C. Low ambient temperature: Fixed installation -40℃ Non-fixed installation -15℃ The rated voltage is below 500V.

This product is suitable for electronic computers and automation connection cables with a rated voltage of 500V and below and high requirements for anti-interference.

Computer cables Computer cables are made of K-type B-type polyethylene with anti-oxidation properties. Polyethylene has high edge resistance, good withstand voltage, small dielectric coefficient, and the influence of dielectric loss temperature and frequency change is small, which can not only meet the requirements of transmission performance, but also ensure the service life of the cable. 1

In order to reduce mutual crosstalk and external interference between loops, the cable adopts a shielded structure. The shielding requirements of cables are adopted according to different occasions: combined shielding of twisted pairs, total shielding of cables composed of twisted pairs, total shielding after combined shielding of twisted pairs, etc.

There are three types of shielding materials: round copper wire, copper tape, aluminum tape/plastic composite tape. The shielding pair and the shielding pair have good J-edge performance. If the potential difference between the shielding pair and the shielding pair occurs in the cable in use, the transmission quality of the signal will not be affected.

technical parameter

The ambient temperature during laying should not be lower than: fixed laying -40℃, non-fixed laying -15℃

Small bending radius: no armor layer should be no less than 6 times the cable outer diameter, and the cable with armor layer should be no less than 12 times the cable outer diameter

At 20℃, the J-edge resistance should not be less than 2500MΩ·Km after stable charging with DC 500V voltage test for 1min

There should be no circuit breakers between each pair of shields and between the pair shields and the overall shield

The cable between the core and the core and the shield should withstand 50HZ, AC 2000V voltage test for 5min without breakdown
