Problems solved by technology

However, these flame-retardant cables will release a large amount of corrosive gas and dense smoke during combustion. The smoke blocks the line of sight and makes it difficult to escape from the fire scene; the toxic gas suffocates people and endangers human safety.

Embodiment Construction

[0013] A low-smoke, halogen-free and high flame-retardant power cable. The structure includes a wire 1, a flame-retardant insulation layer 2 is arranged on the outside of the wire 1, and a carbon fiber flame-retardant layer 3 is arranged on the outside of the flame-retardant insulation layer 2, and the outer side of the carbon fiber flame-retardant layer 3 A foam flame-retardant layer 4 is provided, and the carbon fiber flame-retardant layer 3 and the flame-retardant insulating layer 2 and the carbon fiber flame-retardant layer 3 and the foam flame-retardant layer 4 are connected by a cross-linking layer 5. The flame-retardant insulating layer 2 includes 100 parts by weight of EPDM rubber, 20 parts by weight of calcium carbonate, 7 parts by weight of dicyclopentadiene iron, and 3 parts by weight of acrylic resin. The carbon fiber flame-retardant layer 3 has a spatial network structure, the voids in the network structure are combined with dicyandiamine, the diameter of the carbon...

Abstract

The invention discloses a low-smoke-zero-halogen high-flame-retardance power cable which structurally comprises a guiding wire. A flame retardant insulation layer is arranged on the outer side of the guiding wire. A carbon fiber flame retardant layer is arranged on the outer side of the flame retardant insulation layer. A foam flame retardant layer is arranged on the outer side of the carbon fiber flame retardant layer. The carbon fiber flame retardant layer is connected with the flame retardant insulation layer through a cross-linking layer, and the carbon fiber flame retardant layer is connected with the foam flame retardant layer through a cross-linking layer. According to the low-smoke-zero-halogen high-flame-retardance power cable, power cable flame retardant capacity is improved, and meanwhile release of toxic smoke is lowered during burning.

Description

Technical field [0001] The invention relates to the technical field of cables, in particular to a low-smoke, halogen-free and high flame-retardant power cable. Background technique [0002] Traditional flame-retardant cables mainly use flame-retardant polyvinyl chloride, neoprene rubber, chlorosulfonated polyethylene and other halogen-containing materials as the cable sheath to achieve the purpose of suppressing flame spread. However, these flame-retardant cables will release a large amount of corrosive gas and dense smoke during combustion, and the smoke will block the line of sight and bring difficulties to escape from the fire scene; the toxic gas can suffocate people and endanger people's safety. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a low-smoke, halogen-free and high flame-retardant power cable, which can solve the deficiencies of the prior art, improve the flame-retardant ability of the cable and reduce th...
