Computer cables such as DJYPVP and DJYPVPR are suitable for electronic computers and automation applications with rated voltages of 500V and below, requiring high levels of interference resistance. The cable's ground core insulation utilizes oxidation-resistant K-type B low-density polyethylene. Polyethylene offers high insulation resistance, good voltage resistance, low dielectric constant, and minimal dielectric loss due to temperature and frequency fluctuations. This not only meets transmission performance requirements but also ensures the cable's longevity.
To reduce crosstalk and external interference between circuits, the cables utilize a shielded structure. Shielding requirements vary depending on the application, with options including combined shielding of twisted pairs, overall shielding of the twisted pair cable, and overall shielding after combined shielding of twisted pairs.
Shielding materials include round copper wire, copper tape, and aluminum/plastic composite tape. Shielded pairs provide excellent insulation performance, ensuring that potential differences between shielded pairs during operation will not affect signal transmission quality. II. Cable Models, Names, and Applications
