Overview:
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.
