Shielded cables for computer and instrumentation fall into the category of cables for electrical equipment. The cables adopt a shielded structure to reduce mutual crosstalk between circuits and external interference. Based on different application scenarios, the following shielding methods are selectively adopted for the cables: shielded twisted pair combination, overall shielding for twisted - paired cables, and overall shielding after twisted pair combination shielding. There are three types of shielding materials, namely round copper wire, copper strip and aluminum - plastic composite strip.

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