Computer cable use; Suitable for power generation, metallurgy, petrochemical and other industrial and mining enterprises distribution system, electronic computer system, automation system signal transmission and detection instruments, meters and other connections with multiple pairs of shielded cable.

The conductor of computer cable is tinned wire or bare copper wire without oxygen, J-edge PE and PVC, and the shielding is divided into braided shielding copper tape winding shielding aluminum tape winding shielding, which has good anti-interference effect. Use characteristics: the working temperature generally does not exceed 70℃ model with 105 high does not exceed 105℃. Low ambient temperature: -40℃ for fixed installations -15℃ for non-fixed installations rated voltage below 500V.

This product is suitable for rated voltage 500V and below for high interference resistance of electronic computers and automatic connection cables. Cable ground wire core J

Edge with anti - oxidation performance of K type B polyvinyl. The j-edge of polyethylene has high resistance, good voltage resistance, small dielectric coefficient and the influence of medium loss temperature and variable frequency is also 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 is shielded. Cable shielding requirements are based on different occasions respectively: pair combination shielding, pair composition of cable total shielding, pair combination after total shielding and other methods.

Shielding materials are round copper wire, copper belt, aluminum belt/plastic composite belt three. Shielding pair and shielding pair have better j-edge performance. If potential difference between shielding pair and shielding pair occurs in the use of cable, the transmission quality of signal will not be affected.

Technical parameters

Ambient temperature for laying should not be lower than -40℃ for fixed laying and -15℃ for non-fixed laying

Small bending radius: no less than 6 times of cable diameter for unarmored layer, no less than 12 times of cable diameter for armored layer

The j-edge resistance should not be less than 2500M ω ·Km after stable charging at 20℃ with 500V DC voltage test for 1min

There should be continuous circuits between the pair shielding and between the pair shielding and the main shielding

The core of the cable and between the core and shielding should be subjected to 50HZ, AC 2000V voltage test for 5min without breakdown
