This product is suitable for electronic computers and automation connection cables with high anti-interference requirements for rated voltage of 500V and below. The insulation of the cable ground wire core adopts K-type B-class low-density polyethylene with chemical properties. Polyethylene has high insulation resistance, good voltage resistance, low dielectric constant, and minimal temperature and frequency effects on dielectric loss. It not only meets the requirements of transmission performance, but also ensures the service life of cables.
In order to reduce mutual crosstalk and external interference between circuits, the cable adopts a shielding structure. The shielding requirements for cables are based on different occasions, using methods such as twisted pair combination shielding, total shielding of twisted pair cables, and total shielding after twisted pair combination shielding.
There are three types of shielding materials: round copper wire, copper strip, and aluminum strip/plastic composite strip. Shielding pairs have good insulation performance, and if there is a potential difference between shielding pairs during cable use, it will not affect the quality of signal transmission.
