Classification of fire resistant computer cables

The computer cable ground wire core insulation is made of low density polyethylene with antioxidant properties. Polyethylene has high insulation resistance, good voltage resistance, small dielectric coefficient and the influence of dielectric loss temperature and variable frequency, which can not only meet the requirements of transmission performance, but also ensure the service life of the cable. In order to reduce cross-talk and external interference between circuits, the cable adopts a shielded structure. The shielding requirements of the cable are based on different occasions: the combined shield of the twisted cable, the total shield of the twisted cable, and the total shield after the combined shield of the twisted cable. The shielding material is round copper wire, copper strip, aluminum strip/plastic composite strip three kinds. The shielding pair and the shielding pair have good insulation performance, and the potential difference between the shielding pair will not affect the transmission quality of the signal.

Computer cable usage: This product is suitable for rated voltage 30/500v and below the anti-interference performance requirements of high electronic computers, testing instruments, meters connection. Conditions of use: long-term working temperature of cable conductor: PVC has 70℃, 105℃ two kinds; Polyethylene insulation is 70℃; Cross-linked PVC insulation at 90 ° C. The cable is allowed to be laid at an ambient temperature of -40 ° C to 50 ° C. The cable should be laid in an environment no lower than that of the cable with copper tape shielding structure at 0 ° C. The bending radius of the cable should be no less than 12 times the outer diameter of the cable.

Fire-resistant computer cable 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 shielded cables.

Refractory computer cable use range Use characteristics:
