Environmental-friendly cable

Abstract

The invention discloses an environmental-friendly cable, which comprises a cable core, a silicon rubber insulation layer, an inner protective layer and an outer protective layer, wherein the silicon rubber insulation layer is wrapped on the surface of the cable core; and the inner protective layer and the outer protective layer are wrapped on the surface of the silicon rubber insulation layer in sequence. Compared with the prior art, a fireproofing wrapping tape and a thin aluminum tape are adopted for the inner protective layer, thereby playing a role of protecting the cable, and achieving the fireproofing purpose; an outermost protective jacket is a wrinkled armor made of aluminum wires, thereby playing a flame retardant role; and meanwhile, a silicone rubber material is adopted for an insulation material of the cable, so that after being burned, the environmental-friendly cable is low in heat release rate, high in carbon forming rate, non-toxic and low in smoke and the like, so that real environment protection can be realized.

Description

technical field [0001] The invention relates to a telecommunication cable, in particular to an environment-friendly cable. Background technique [0002] With the enhancement of people's awareness of environmental protection and safety, wires with the characteristics of light weight, small size, low smoke, non-toxic, and fire prevention are very popular. Some of them are made by adding flame-retardant materials such as aluminum hydroxide and magnesium hydroxide, Some are by adding a little more flame retardant to the insulating material and filling material. Adding flame retardant material to the cable will reduce the electrical and mechanical properties of the cable. Adding too much flame retardant to the insulating material will cause its insulation performance to decline. It seems that these can not really meet people's demand for non-toxic, smoke-free, environmental protection and safety of cables.
