Computer cable
The product rated voltage 500 V and the following for the interference of the high sex requirement electronic computer [1] and automation connectivity with cable. Cable wire core insulation is with antioxidant properties of the type K class B low density polyethylene. Polyethylene high insulation resistance, good withstand voltage, dielectric coefficient little and medium loss temperature and frequency variation of the influence of the small, not only can meet the requirements of the transmission performance, and can ensure the service life of the cable.
In order to reduce the loop of mutual crosstalk and external disturbance, the cable shielding structure. Cable shielding requirements according to different situations is were used to wring combination: insulation, and the composition of the cable to wring total shielding, to wring combination shielding total shielding and other methods after.
Shielding materials have round copper wire, copper strip, aluminum take/plastic composite with three. Shielding and shielding of to have good insulation and cable in use if to shield between appear to shield potentials, will not affect signal transmission quality.
