Brief description: Shielded cables for electronic computers are insulated with high-voltage polyethylene with a low dielectric constant. Adopting structural forms such as twisted pair, screen pair, and total screen (or three wire combination, 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 and can be widely used in computer systems or automation devices for detection and control in power generation, metallurgy, petroleum, chemical, textile and other departments, as well as general industrial computers.

flame retardantMeaning: Under specified test conditions, the specimen is burned, and after removing the ignition source, the flame spreads only within a limited range on the specimen and extinguishes on its own, which means it has the ability to prevent or delay the occurrence or spread of flames.

The combustion of wires, cables, and cables is caused by the generation of flammable gases through external heating. To achieve flame retardancy, it is necessary to suppress the three elements that cause combustion, namely flammable gases, heat, and oxygen. Therefore,Flame retardant wires and cablesThe commonly used method is to add halides and metal oxides containing halogens to the sheath material. From the perspective of flame retardancy, this is the * method. However, due to the presence of halides in these materials, a large amount of smoke and hydrogen halide gas are released during combustion, resulting in low visibility during a fire and greatly hindering the safe evacuation and firefighting of personnel. People are more likely to suffocate and die from toxic gases.

In addition, once hydrogen halide gas reacts with water in the air, it generates“Hydrogen halide acid”Severe corrosion of instruments, equipment, and buildings“Secondary disasters”.

At present, with the continuous improvement of technology, the problem of flame retardancy has further developed from halogen flame retardancy in the past to low halogen and halogen-free flame retardancy.
