Choose high-voltage polyethylene insulation with a low dielectric constant. Adopting structural forms such as twisted pair, screen pair, and total screen (or three wire twisted pair, group shielding, group screen total screen), it has the characteristics of low dielectric loss, strong signal transmission ability, and good anti-interference performance. It can reliably transmit weak analog signals or digital signals, and can be widely used in computer systems or automation instrument devices for detection and control in power generation, metallurgy, petroleum, chemical, textile and other departments, as well as general industrial computers. Related technical indicators: Refer to IEC189 and British BS5308 standards
