Manufactur standard Transflash/Sd Extension Cable - Computer Cable – Sunshow

Product Introduction
This product is suitable for electronic computers and automation connection cables with a rated voltage of 500v and below that require high interference resistance.
Computer cable
The edge adopts K-type b-type low-density polyethylene with oxidation resistance. Polyethylene has high insulation resistance, good withstand voltage, low dielectric coefficient and low dielectric loss temperature and variable frequency. It can not only meet the requirements of transmission performance, but also ensure the service life of the cable.
In order to reduce the mutual crosstalk and external interference between loops, the cable adopts a shielded structure. Cable shielding requirements are adopted according to different occasions: pair-pair combined shielding, pair-twisted total shielding of the cable, total shielding after pair-pair combined shielding, etc.
There are three types of shielding materials: round copper wire, copper tape, aluminum tape/plastic composite tape. The shielding pair and the shielding pair have good insulation performance. If the potential difference between the shielding pair and the shielding pair occurs during the use of the cable, the signal transmission quality will not be affected.
