Shielded cables for computers and instrumentation are classified as electrical equipment cables. They adopt a shielded structure to reduce mutual crosstalk between circuits and external interference. According to different application scenarios, the cables use selective shielding methods: shielded twisted pair combination, overall shielding for twisted-pair cables, and overall shielding after twisted pair combination shielding. Three types of shielding materials are available: round copper wire, copper strip, and aluminum-plastic composite strip.

They are suitable for connecting electronic computer networks and control systems with high anti-interference requirements, as well as detection devices and instruments that demand excellent anti-interference performance, with a rated voltage of 300/500V and below.
