Description
Technical field:
The utility model relates to a kind of cable, is specifically related to a kind of fire resistant flame retardant polyvinyl chloride butyronitrile composition polymer insulated cable.
Background technology:
In generating, metallurgical, chemical industry, as the cable that work electric line between priming electric equipment lays in the adverse circumstances such as harbour, because production environment temperature is high, cable is easily aging, reduce the useful life of cable design, improve cable replacement frequency, in production, cable running time under the time limit that cable frequency of utilization normally uses according to cable design and varying environment, empirically determine, in order to avoid cable breakage accident, increase coefficient of safety, cable value in useful life is less, replacement cycle is short, change frequent, waste a large amount of manpower and materials and financial resources, thus the replacement cycle is shortened, reduce cable cost, use manpower and material resources sparingly, enhance productivity and become this type of cable urgent problem, and how to improve the integrated performance index of such cable, as: fire-retardant, fire-resistant, good weatherability, soft, carry out the emphasis that the selection of material and architecture advances are industry work.
Utility model content:
The purpose of this utility model is to provide a kind of fire resistant flame retardant polyvinyl chloride butyronitrile composition polymer insulated cable, soft and have good oil resistance, corrosion resistance ageing-resistant performance, has fire-retardant and fire-resistance property concurrently simultaneously.Be applicable to the connecting line laid as work electric line between priming electric equipment in the frequent mobile environment such as generating, metallurgy, chemical industry, harbour.
In order to solve the problem existing for background technology, the utility model is by the following technical solutions:
A kind of fire resistant flame retardant polyvinyl chloride butyronitrile composition polymer insulated cable, include conductor, described conductor is formed by multiply bare copper conductor is stranded, insulating barrier is extruded with outside described conductor, be surrounded with lapping layer outside described insulating barrier and form insulated wire cores, tension bar is enclosed with in described lapping layer, the stranded formation cable core of insulated wire cores described in four, belting layer is surrounded with outside described cable core, screen is woven with outside belting layer, be provided with many drain wires between described screen and belting layer, outside described screen, be extruded with oversheath.
Described insulating barrier is made up of flame-proof polyvinyl chloride butyronitrile composite polymeric materials.
Described belting layer is made up of fire-resisting ceramic silicone rubber band material.
Described lapping layer is double-deck, and lapping layer material is one side synthetic mica tape, described tension bar be located at lapping layer two-layer between.
Described oversheath is made up of flame-proof polyvinyl chloride butyronitrile composite polymeric materials.
In the utility model, conductor adopts strands naked copper copper five class conductor, and five class conductors have the characteristic of structurally flexible than a class, two class conductors, while stranded conductor can improve the pliability of conductor, compared with single conductor, not easy fracture, coefficient of safety is high; The flame-proof polyvinyl chloride butyronitrile composite polymeric materials that insulating barrier and jacket material adopt, this kind of material has good flexibility, cold resistance, resistance to bend(ing), excellent percentage elongation, grease resistance, anti-flammability, outstanding resistance to ozone and weatherability is resistance to worn, tearing strength is high is a kind of desirable mobile device cable insulation and sheath material; Band adopts fire-resisting ceramic silicone rubber band material, makes cable band when flame combustion form ceramic flame retardant coating, effective starvation, guarantee cable fire requirement, lapping layer is double-deck, and lapping layer material is one side synthetic mica tape, has stronger fire resistance.
The beneficial effects of the utility model: the utility model is soft and have good oil resistance, corrosion resistance ageing-resistant performance, be applicable to the field such as generating, metallurgy, chemical industry, have fire-resistant and flame-retarding characteristic simultaneously concurrently, be applicable to very much the connecting line laid as work electric line between priming electric equipment in the frequent mobile environment such as harbour.
