A cross-linked polyethylene insulated low-smoke halogen-free flame-retardant computer cable

Abstract

The invention discloses a cross-linked polyethylene insulated low-smoke halogen-free flame-retardant computer cable, which comprises a waterproof protective sheath, a total shielding layer, a filler, an isolation layer, a phase-separated shielding layer, a polyester film tape, an insulating layer, and a cable core , a clamping block and a second magnetic ring, the inside of the waterproof protective cover is provided with a total shielding layer, the inside of the total shielding layer is provided with two fillers, and the inside of the total shielding layer is provided with two isolation layers, The insides of the two isolation layers are all provided with a phase-splitting shielding layer, and the sides of the two phase-separation shielding layers away from the isolation layer are all provided with polyester film strips, and the insides of the two described polyester film strips are all provided with There are two insulating layers, and the interior of the four insulating layers is equipped with cable cores; low-halogen low-smoke flame-retardant polyvinyl chloride not only has flame-retardant properties, but also has low smoke generation and low HCl gas volume during combustion. Features: The cable core is twisted with concentric layers, and the transmission parameters are stable, which can reduce electromagnetic coupling and improve anti-interference performance.

Description

technical field [0001] The invention belongs to the field of computer cables, in particular to a cross-linked polyethylene insulated low-smoke halogen-free flame-retardant computer cable. Background technique [0002] Computer cables require high rated power and good anti-interference performance. The traditional cable ground core insulation is made of low-density polyethylene material with anti-oxidation properties. At present, computer cables are widely used in power generation, metallurgy, petroleum, chemical industry and light textile departments. Therefore, it has higher requirements for its signal transmission ability and anti-interference ability, so that weak analog signals can be transmitted reliably; [0003] The existing computer cables still have certain defects in use. When installing the computer cables, because the length of the cables is relatively fixed, the cables cannot be spliced, so that the length of the cables cannot be conveniently controlled. When a ...

Problems solved by technology

[0003] Existing computer cables still have certain defects in use. When installing computer cables, the length of the cables is relatively fixed, and the cables cannot be spliced, so that the length of the cables cannot be conveniently controlled. When a certain section of the cable breaks , it is not convenient to quickly disassemble and replace it, and the wires inside the cable affect each other due to electrical properties, which does not play a good role in insulation and isolation, thereby reducing the efficiency of information transmission. Therefore, it is necessary to design a cross-linked polymer Vinyl insulated low smoke halogen free flame retardant computer cable
