Shielded cables for electronic computers are insulated with high-voltage polyethylene with small dielectric constant. The use of twisted pairs, pairs of screens, total screen (or three-wire combination, group shielding, group screen total screen) and other structural forms, with small dielectric loss, transmission of the number of strong transmission capacity, good anti-jamming properties, etc., can reliably transmit weak analog signals, can be widely used in power generation, metallurgy, petroleum, chemical industry, textiles and other sectors of the detection and control of computer systems or automation devices, as well as the general industrial computers.
