Flame-retardant flame-proof wrapping tape for cable

Abstract

The invention provides a flame-retardant flame-proof wrapping tape for a cable. The flame-retardant flame-proof wrapping tape comprises a plurality of conductors, inner insulating layers arranged on the corresponding conductors in a sleeving mode, outer insulating layers arranged on the corresponding inner insulating layers in a sleeving mode, and a cable connector connected with the side walls ofthe multiple conductors, wherein the multiple outer insulating layers prop against together. According to the flame-retardant flame-proof wrapping tape, the defects in the prior art are overcome; thedesign is reasonable, and the structure is compact; by virtue of a sheath, an armored layer and ceramic silicon rubber fireproof blocks, an effect of flame isolation is achieved, so that the cable isprevented from being damaged by flames; an elastic plate is driven to be bent through a compression spring, and the melted fireproof rubber particles are sprayed to the flame, so that a fire extinguishing effect can be achieved; and meanwhile, the elastic plate and a filling agent play a role in fire insulation and flame retardancy again, so that the fire-resistant, flame-retardant and fire-extinguishing effects are achieved through multiple measures, while very high practicability is realized.

Description

technical field [0001] The invention relates to the technical field of cable wrapping flame-retardant equipment, in particular to a flame-retardant and fire-proof wrapping tape for cables. Background technique [0002] According to statistics, about 60% of fire accidents are caused by electrical faults. As people's understanding of the danger of fire caused by wire and cable problems continues to deepen, the performance requirements for fire and flame retardancy of wire and cable are also gradually increasing. [0003] The cables are mainly distributed on the ground or in the wall, and the cable fires are mainly concentrated in the exposed cable joints. During operation, the cable joints are oxidized, heated and flow glue. The above factors can cause insulation breakdown, form a short circuit, and cause the cable to explode and catch fire; After long-term use, the cable joints are also prone to flashover and fire, causing the surface insulation of the cable head and the ins...
