Product description:



A, product introductionThis product is suitable for rated voltage 500 v and below for the requirement of disruptive high electronic computer and automation connectivity cable.Ground cable core insulation is with antioxidant properties of K type B type low density polyethylene.Polyethylene high insulation resistance, good resistance to voltage, small dielectric coefficient and temperature and the influence of variable frequency dielectric loss is small, can not only meet the requirements of transmission performance, and can ensure the service life of the cable.In order to reduce the mutual crosstalk between circuit and external interference, cable adopts block structure.Cable shielding requirements according to different situations are: to shielding with combination, and the ground of the total of the cable shielding, after the pair shielding with combination method such as total shielding.Shielding materials have round copper wire, copper strip, aluminum strip/plastic composite with 3 kinds.Shield to shield has good insulation performance, cable in use when a potential difference between a shield to shield the, will not affect the quality of signal transmission.Second, the cable model, name and use range
