Abstract

The utility model discloses a high temperature resistant and warp resistant flexible cable, comprising a plurality of groups of conductors. Each group of conductors is wrapped by a composite fireproof layer, an insulating layer and a slip layer in sequence to form an insulation core; a first mica tape, a fireproof inorganic short fiber bonding layer and a winding and cladding layer are wrapped outside the composite fireproof layer in sequence from interior to exterior; a plurality of insulation cores are intertwisted to form a cable core; the cable core is covered with a second mica tape and an inner sheath formed by intersection braiding; an outer sheath is wrapped outside the inner sheath; and a filling layer is arranged between the cable core and the second mica tape. According to the high temperature resistant and warp resistant flexible cable, a good warp resistant capability is provided, bending is convenient, the service life is long, the composite fireproof layer and the second mica tape are employed, duel-layer fireproof protection is provided for the cable, the high temperature resistance of the cable is effectively enhanced, and the usage safety when the cable is burned at high temperature is guaranteed.

Description

A kind of high temperature resistant warp resistance flexible cable
Technical field
The utility model relates to the electric wire field, is specially a kind of high temperature resistant warp resistance 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 relatively poor structure of thermal insulation, not flame resistant, high temperature.Therefore; in breaking out of fire or when being subjected to temperatures involved; 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 subjected 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 influence easy deformation, cause shorten the useful life of cable.
The utility model content
The purpose of this utility model provides a kind of high temperature resistant warp resistance flexible cable, not good to solve cable resistance to elevated temperatures traditional in the prior art, cause cable short circuit easily and cisco unity malfunction when being subjected to the flame calcination, and anti-twist scarce capacity, be difficult for bending, be subjected to distortion, bending to influence easy deformation, the problem that useful life is short.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of high temperature resistant warp resistance flexible cable, include the array conductor, it is characterized in that: every group of conductor all is coated with composite fire layer, insulating barrier and glide lamella outward successively, and formation insulated wire cores, described composite fire layer is followed successively by first mica tape, fire-resistant inorganic short fiber adhesive-layer and lapping layer from inside to outside, the stranded formation cable core of several insulated wire cores, described cable core is coated with the inner sheath that second mica tape and interlacing constitute outward successively, described inner sheath is coated with oversheath, is provided with packed layer between described cable core and second mica tape.
Described a kind of high temperature resistant warp resistance 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 high temperature resistant warp resistance flexible cable is characterized in that: described glide lamella is the macromolecule material film layer of low-friction coefficient.
Described a kind of high temperature resistant warp resistance 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, adopts the design of composite fire layer and second mica tape, for cable provides double-deck high temperature resistant protection, has promoted the resistance to elevated temperatures of cable effectively, has guaranteed the use safety of cable when being subjected to high temperature sintering; Employing coats the design of glide lamella outside insulating barrier, make and have good slipping property between each insulated wire cores, convenient bending, and inner sheath adopts the design of interlacing, the interlacing structure has bigger extending space, promote the anti-twist ability of cable effectively, prolonged the useful life of cable.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of high temperature resistant warp resistance flexible cable, include array conductor 1, every group of conductor 1 outer composite fire layer, insulating barrier 5 and glide lamella 6 of all being coated with successively, and formation insulated wire cores, the composite fire layer is followed successively by first mica tape 2, fire-resistant inorganic short fiber adhesive-layer 3 and lapping layer 4 from inside to outside, the stranded formation cable core of several insulated wire cores, cable core is coated with the inner sheath 8 of second mica tape 7 and interlacing formation outward successively, inner sheath 8 is coated with oversheath 9, is provided with packed layer 10 between cable core and second mica tape 7.
Fire-resistant inorganic short fiber adhesive-layer 3 adopts polycrystal alumina or polycrystalline mullite short fiber to make, and glide lamella 6 is the macromolecule material film layer of low-friction coefficient, and oversheath 9 adopts acrylonitrile-butadiene rubber to make.
