Network strong-interference resistance armored signal transmission cable for mine safety detection

Abstract

The invention relates to a network strong-interference resistance armored signal transmission cable for mine safety detection, and belongs to the technical field of electric wires and cables. The network strong-interference resistance armored signal transmission cable for the mine safety detection comprises insulating wire cores, wherein conductors of the insulating wire cores are provided with insulating layers in an extruded mode, separated shields are weaved after pair twist is carried out on the insulating wire cores, a cable core is formed by the separated shields in a cabling mode, and a shielding layer, an inner protective layer, a corrosion preventing armor layer and a sheath are arranged on the cable core. The network strong-interference resistance armored signal transmission cable for the mine safety detection is reasonable and simple in structure, easy to produce and manufacture, low in cost and good in using performance, saves laying space, and is convenient to install. The network strong-interference resistance armored signal transmission cable for the mine safety detection has multiple functions, such as the function of voltage resistance, the function of strong interference resistance, the function of flame retardance and fire protection, the function of corrosion resistance, the waterproof function and the function of external-force impact resistance. The network strong-interference resistance armored signal transmission cable for the mine safety detection is an ideal cable for places of tunnels and pits.

Description

technical field [0001] The invention relates to a wire and cable, in particular to a network anti-strong interference armored signal transmission cable for mine safety detection. Background technique [0002] Network anti-strong interference armored signal transmission cables for mine safety detection are mainly used in tunnels and pits. In these occasions, due to environmental and work needs, most cables only undertake a single function when laying. After laying, the cable is flame-retardant in case of fire. The performance cannot meet the requirements of on-site disaster relief, especially the cables with poor flame retardancy will extinguish for a long time after burning, which will bring great difficulties to disaster relief work and cause greater disasters. In the past, improved material formulas were used to improve the resistance of insulating sheath materials. The impact performance and the flame retardancy of cables can only solve part of the problem. In these speci...

[0002] Network anti-strong interference armored signal transmission cables for mine safety detection are mainly used in tunnels and pits. In these occasions, due to environmental and work needs, most cables only undertake a single function when laying. After laying, the cable is flame-retardant in case of fire. The performance cannot meet the requirements of on-site disaster relief, especially the cables with poor flame retardancy will extinguish for a long time after burning, which will bring great difficulties to disaster relief work and cause greater disasters. In the past, improved material formulas were used to improve the resistance of insulating sheath materials. The impact performance and the flame retardancy of cables can only solve part of the problem. In these special environments, the impact resistance of cables and the high flame retardancy of cables have not been fundamentally resolved. As long as such problems occur, resources will be wasted and the Construction creates difficulties and major safety hazards
