DJYPVP, DJYPVPR cables and other computer cables are suitable for electronic computers and automation connection cables with a rated voltage of 500V and below that require high anti-interference. "Cable Treasure Cable Application Technology Research Institute" mentioned that the cable ground core insulation adopts K-type B low-density polyethylene with anti-oxidation properties. Polyethylene has high insulation resistance, good withstand voltage, small dielectric coefficient, and the influence of dielectric loss temperature and frequency change is small, which can not only meet the requirements of transmission performance, but also ensure the service life of the cable. In order to reduce mutual crosstalk and external interference between loops, the cable adopts a shielded structure. The shielding requirements of cables are adopted according to different occasions: combined shielding of twisted pairs, total shielding of cables composed of twisted pairs, total shielding after combined shielding of twisted pairs, 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 transmission quality of the signal will not be affected.
