Embodiment Construction

[0013] The present invention will be further described below in conjunction with accompanying drawing;

[0014] Such as figure 1 As shown, a low-smoke, halogen-free, flame-retardant and fire-resistant electronic computer cable includes a cable inner core and a cable outer layer. The cable inner core is made of a polyester tape 3 and a separate shielding aluminum-plastic composite tape 4 to extrude the insulating power core from the inside to the outside The insulated power core is formed by extruding polyethylene insulation layer 2 to wrap conductor 1; a ground wire 5 is arranged in separate shielding aluminum-plastic composite tape 4; the outer layer of the cable is extruded with flame-retardant mesh from inside to outside Shaped filling rope 6, PP wrapping tape inner lining 7, general shielding aluminum-plastic composite tape 8 and a low-smoke, halogen-free, flame-retardant and fire-resistant sheath layer 9 including a ground wire 5.

[0015] The number of cable inner core...

Abstract

A low-smoke halogen-free flame-retardant fireproof electronic computer cable disclosed by the present invention comprises a cable inner core and a cable outer layer. The cable inner core is formed by extruding a polyester tape and a separately shielding aluminum plastic compound tape on an insulating power wire core from inside to outside, the insulating power wire core is formed by extruding a polyethylene insulating layer on a conductor, and a ground wire is arranged in the separately shielding aluminum plastic compound tape. A flame-retardant netted filling tape, a PP wrapping tape lining layer, a total shielding aluminum plastic compound tape and a low-smoke halogen-free flame-retardant fireproof sheath layer containing a ground wire are extruded on the cable outer layer orderly from inside to outside. The cable of the present invention does not release a harmful gas and the smog when burning, does not cause a secondary disaster, is high in safety, is environment friendly, has no pollution, can be laid in various specific occasions, enables the service life of a product to be prolonged, and accords with an european union ROHS standard, thereby meeting the design requirements of being innovative in science and technology, being green environmental protection, being safe and having no pollution.

Description

technical field [0001] The invention relates to cables, in particular to a low-smoke, halogen-free, flame-retardant, fire-resistant electronic computer cable. Background technique [0002] In a fire scene, the cable is an extremely dangerous material for transmitting flames and expanding the scope of the fire. When the cable burns, it can produce a large amount of dense smoke, which makes rescue work difficult, and the dense smoke contains a large amount of halogen gas, which aggravates the rescue. hazard to personnel. According to the analysis of the causes of 1,464 people killed in 393 building fires in the United States, 1,062 people died of poisoning and lack of oxygen, accounting for 75.5% of the total number of deaths, and 359 people were directly burned to death by flames, accounting for only 24.4%. . A large amount of smoke and poisonous gas will knock people down, and they will be burned to death if they cannot leave the scene, which also makes it difficult to fig...
