I. Introduction computer cable DJYVP 7 * 0.75
This product is suitable for rated voltage 500V and below for the anti-tampering requirements of high computer and automation connection cables. Ground cable core insulation K Class B low density polyethylene with antioxidant properties. Polyethylene insulation resistance and withstanding voltage, dielectric constant temperature and variable frequency of small and medium loss, not only meets the requirements of the transmission performance, and ensure that the cable life.
In order to reduce the circuit crosstalk and external interference, shielded cable structure. The cable shielding requirements are based on different occasions were used: shielded twisted pair combination of the total shielding twisted pair cable, shielded twisted pair combination after the total shielding method.
Shielding materials are round copper wire, copper strips, aluminum / plastic composite with three kinds. Shielded with the shield has good insulating properties, the cable in use shield between the shield on the potential difference will not affect the signal transmission quality.
