Abstract
The utility model relates to a multi-core twisted conductor fireproof cable comprising a cable conductor. The cable conductor is wrapped in a continuously-extruded aluminum sleeve. The continuously-extruded aluminum sleeve is wrapped in a wrapping layer 2. The wrapping layer 2 is wrapped in a filling layer. The filling layer is wrapped in a wrapping layer 3. The wrapping layer 3 is wrapped in an extruded layer. The cable conductor comprises a plurality of groups of twisted wires. Each group of twisted wires comprises two twisted metallic wires and is wrapped in a wrapping layer 1. The wrapping layer 1 comprises a plurality of mica tape layers. The multi-core twisted conductor fireproof cable uses the mica tape and ceramic silicone rubber as the wrapping layers so as to achieve production cost less than that of a conventional magnesium oxide fireproof cable. The multi-core twisted conductor fireproof cable is provided with the continuously-extruded aluminum sleeve in order to achieve a supporting effect and prevent the cable from easily fracturing. The cable comprises three wrapping layers and one glass fiber filling layer so as to completely guarantee fireproof, fire-resistant, high-temperature-resistant, and insulated performance of the cable.
Description
Technical field
The utility model relates to a kind of multicore stranded conductor fireproof cable.
Background technology
Cable is in actual life, to need a large amount of a kind of power transmission devices that use, and can carry out the long-distance transmissions of electric power, brings great convenience to people's work, life.Along with expanding economy, building develops to high level, the accelerating development of the increase of various electric installations and power grid construction, and disaster hidden-trouble also increases thereupon, has increased the danger level of breaking out of fire.According to statistics, in many fire incidents, the fire being caused by electric wiring reaches 80%.Fire not only can cause a large amount of economic losses, also can produce a large amount of poisonous and hazardous gas in cable combustion process, causes environmental pollution.
Utility model content
The purpose of this utility model is to provide a kind of multicore stranded conductor fireproof cable, to overcome prior art above shortcomings.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of multicore stranded conductor fireproof cable, comprises cable conductor, and described cable conductor is provided with outward and extrudes continuously aluminium cover, the described outer lapping layer two that is provided with of aluminium cover that extrudes continuously, described lapping layer two is outer is provided with packed layer, and described packed layer is provided with lapping layer three outward, and outer being provided with of described lapping layer three extrudes layer; Described cable conductor comprises some groups of stranded conductors, and described every group of stranded conductor comprises two mutual stranded plain conductors, and described every group of stranded conductor is all enclosed with lapping layer one outward.
Further, described lapping layer one comprises some stratus master tapes.
Further, described lapping layer two and lapping layer three form by ceramic silicon rubber.
Further, described packed layer is made up of glass fibre.
Further, described in, extruding layer is made up of low smoke and zero halogen material.
The beneficial effects of the utility model are: adopt mica tape and ceramic silicon rubber as lapping layer, cost of manufacture is lower than existing magnesium oxide fire-resisting cable; Be provided with and extrude continuously aluminium cover, can play a supporting role, prevent that cable is bent easily; Cable comprises three layers of lapping layer and layer of glass packed layer, fully ensures fireproofing of cable, fire-resistant, high temperature resistant and insulating properties.
