Technical field
The utility model relates to a kind of power cable, relates in particular to a kind of one-step method silanes crosslinked low smoke and zero halogen category-A flame-retardant aluminium alloy electric power cable.
Background technology
Along with the development of the modernization of industry and the reinforcement of people's fire-fighting consciousness, particularly after " Fire Prevention Law " that China promulgates comes into force, all trades and professions have also had further raising to the attention degree of electric wire anti-flammability, important public places such as many modern office buildings, hotel, market, subway, railway station, residential building, decorate more and more luxurious, the combustible that uses is more and more, and this just requires circuit to adopt the good cable of fire resistance, in order to reduce fire damage.The sheath that present flame retardant cable adopts polyvinyl chloride to add the fire retardant manufacturing more carries out fire-retardant, but this method rises cable cost significantly; In addition, owing to contain a large amount of halogens in the fire retardant, electric wire will be emitted a large amount of poison gas, acid mist and flue gas when burning, these combustion products not only threat to life are complete, contaminated environment, also can cause the heavy corrosion of equipment and building, withdraw and rescue property for fire extinguishing, fire-extinguishing and lifesaving and personnel and cause very big obstacle.Therefore promoting people to research and develop the clean and environment-friendly power cable of low cigarette, Halogen, low toxicity, is the trend of current flame-retardant electric wire and cable development.
The utility model content
The purpose of this utility model provides a kind of one-step method silanes crosslinked low smoke and zero halogen category-A flame-retardant aluminium alloy electric power cable, to overcome present existing cable above shortcomings.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of one-step method silanes crosslinked low smoke and zero halogen category-A flame-retardant aluminium alloy electric power cable, comprise some cores, described core comprises conductor, is coated on the outer fire-resistant belt of conductor and is coated on the outer insulating barrier of fire-resistant belt, core is coated with fire-retardant belting layer, be provided with flame-retardant filler between fire-retardant belting layer and the core, described fire-retardant belting layer is coated with the aluminium alloy compound belt, the aluminium alloy compound belt is coated with fire-retardant inner cushion layer, fire-retardant inner cushion layer is coated with armour, and armour is coated with fire retardant jacket.
Further, described conductor is aluminum alloy materials.
Further, described fire-retardant belting layer and flame-retardant filler are low smoke and zero halogen category-A fire proofing.
Further, described insulating barrier adopts low density polyethylene (LDPE) adding liquid silane to carry out the crosslinked cross-linking polyethylene materials that forms.
Further, described fire retardant jacket adopts the flame-retardant material.
The beneficial effects of the utility model are: the fire proofing in this cable is nuisanceless, pollution-free, do not produce noxious substance in the use, when burning, do not produce thick smoke and toxic gas, non-environmental-pollution, both satisfied the requirement of electric, the mechanical performance of cable, have good flame-retardant performance again, safe and reliable, practical.
