Description:
Fourth, Computer Cable Structure
1. Introduction:
This product is suitable for computer and automation connection cables with high requirement of anti-tampering and rated voltage 500V and below. Ground cable core insulation uses K Class B low density polyethylene with antioxidant properties. High polyethylene insulation resistance and withstanding voltage, small dielectric coefficient, dielectric constant temperature and variable frequency, not only meets the requirements of the transmission performance, but also 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: twisted combination shielding, twisted cable assembly shielding, twisted combination total shielding method.
Shielding materials are round copper wire, copper strips, aluminum / plastic composite strips. Shielded with good insulating properties, if there is potential difference, it will not affect the signal transmission quality.
