Abstract

The utility model discloses a torsion-resistant, fireproof and flame-retardant flexible cable which comprises a plurality of sets of conductors. A composite fireproof layer and an insulated layer are successively coated outside each set of conductors, and an insulated wire core is formed. The composite fireproof layer is composed of the following components successively from inner part to outer part: a mica tape, a fireproof inorganic short-fiber adhesive layer and a coiled layer. A slipping layer is coated outside each insulated wire core. A plurality of insulated wire cores are intertwisted for forming a cable core. A glass fiber tape is coated outside the cable core. An inner sheath which is formed through interweaving is coated outside the glass fiber tape. An outer sheath is coated outside the inner sheath. A filling layer is provided between the cable core and the glass fiber tape. The torsion-resistant, fireproof and flame-retardant flexible cable has the following advantages: simple structure, better torsion resistance, better fireproof and flame-retardant performance, good slipping performance between the insulated wire cores, high convenience in bending, no easy deformation, prolonged service life, and high use safety.

Description

A kind of warp resistance fire resistant flame retardant flexible cable
Technical field
The utility model relates to the electric wire field, is specially a kind of warp resistance fire resistant flame retardant flexible cable.
Background technology
Along with the fast development of power industry, urban construction, all trades and professions are more and more higher to the requirement of cable.The employing that traditional cable is more the poor structure of thermal insulation flame resistant not.Therefore; when breaking out of fire; the not flame resistant baking of this class cable is difficult to isolated flame, so flame these protective layers that are easy to ablate; make cable directly be subject to the calcination of flame; cause cable can not work because of short circuit, and the anti-twist scarce capacity of common cable, be difficult for bending; be subjected to distortion, bending to affect easily and deform, cause shorten the useful life of cable.
The utility model content
The purpose of this utility model provides a kind of warp resistance fire resistant flame retardant flexible cable, to solve traditional anti-twist scarce capacity of cable in the prior art, be difficult for bending, fire resistance is not good, is twisted easily, bends the problem that causes cable shortening in useful life and be short-circuited with the flame calcination that affects during use.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of warp resistance fire resistant flame retardant flexible cable, include the array conductor, it is characterized in that: every group of conductor all is coated with composite fire layer and insulating barrier outward successively, and formation insulated wire cores, described composite fire layer is followed successively by mica tape from inside to outside, fire-resistant inorganic short fiber adhesive-layer and lapping layer, every eradication edge core is coated with glide lamella, the stranded formation cable core of several insulated wire cores, described cable core is coated with glass fiber tape, described glass fiber tape is coated with the inner sheath that interlacing consists of, described inner sheath is coated with oversheath, is provided with packed layer between described cable core and the glass fiber tape.
Described a kind of warp resistance fire resistant flame retardant flexible cable is characterized in that: described fire-resistant inorganic short fiber adhesive-layer adopts polycrystal alumina or polycrystalline mullite short fiber to make.
Described a kind of warp resistance fire resistant flame retardant flexible cable is characterized in that: described glide lamella is the macromolecule material film layer of low-friction coefficient.
Described a kind of warp resistance fire resistant flame retardant flexible cable is characterized in that: described oversheath adopts acrylonitrile-butadiene rubber to make.
The beneficial effects of the utility model are:
The utility model is simple in structure, and inner sheath adopts the design of interlacing, and the interlacing structure has larger extending space, has effectively promoted the anti-twist ability of cable; Adopt the design of composite fire layer and glass fiber tape, for cable provides double-deck refractory protection, effectively promoted the fire resistance of cable, guaranteed the use safety of cable when being subjected to high temperature sintering; Employing, conveniently bends so that have good slipping property between each insulated wire cores in the design of insulated wire cores outer cladding glide lamella, and not yielding, has prolonged the useful life of cable.
