Technical field
The utility model relates to Power-line technology fields, and in particular to a kind of low-smoke non-halogen flame-retardant cold resistant cable.
Background technique
Flame retardant cable is widely used in high-temperature service and the higher occasion of some temperature, flame retardant cable require resistance to height
Temperature, fire resisting fire protecting performance, in the case where providing experimental condition, sample is burned, and after removing test fire source, the sprawling of flame is only being limited
Determine in range, residual flame or it is residual burn within a limited period of time can self-extinguish cable.Basic characteristic is: in case of fire it is possible that
It is burned and cannot run, but the sprawling of the intensity of a fire can be prevented.Generally, burning can be limited in office just in case catching fire by electric wire
Within the scope of portion, sprawling is not generated, is kept other various equipment, is avoided bigger loss.Used in existing flame retardant cable
Material in there are fire retardants as fire proofing material, above-mentioned fire retardant generally selects the combustion-supporting material of Halogen or low halogen, resistance
Although combustion cloth itself is able to solve the pollution problem generated when above-mentioned cable fire, many cables are in cold region
In use, plastics and part rubber material have become embrittlement, cracking, or even there is natural cracking obscission, let alone into
Row cable laying is constructed.Common cable, which carries out construction laying in this condition, just will appear cable insulation and sheath cracking, conductor
It is exposed and be not available.This is just affected to project progress, brings difficulty to the life of the people.
Utility model content
The purpose of this utility model is to provide a kind of low-smoke non-halogen flame-retardant cold resistant cables, so that the cotton covered wire has well
Low temperature resistance.
In order to achieve the above purposes, the technical solution adopted by the utility model is:
A kind of low-smoke non-halogen flame-retardant cold resistant cable, including core, the core are arranged in the bayonet of bracket, the bayonet
It is provided with flame retardant coating outside, the gap filling between the flame retardant coating and bracket has heat-preservation cotton, support is provided with outside the flame retardant coating
Rubber layer, the support rubber layer are provided with fire retardant layer outside, and the fire-retardant layer of cloth peripheral hardware is equipped with silastic-layer.
Compared with prior art, the technical effect that the utility model has are as follows: above-mentioned core is fastened on the bayonet of bracket
It is interior, to realize effective fixation to core, flame retardant coating, support rubber layer and fire-retardant layer of cloth are arranged outside bracket and core, thus
It can ensure that fireproofing of cable performance, and be equipped with silastic-layer in fire-retardant layer of cloth peripheral hardware, which can effectively improve cable
Low temperature resistance, improve the service life of cable.
