Abstract
The utility model discloses a tensile flexible cable resistant to high temperature and warp. The flexible cable comprises a plurality of conductors. Each conductor is successively wrapped in a composite fireproof layer, an insulating layer, and a sliding layer so as to form an insulating wire core. The composite fireproof layer comprises a first mica tape, a fireproof inorganic short fiber adhesive layer, and a wrapping layer from inside to outside. The multiple insulating wire cores and reinforcing steel cores are twisted to form a cable core. The cable core is successively wrapped in a second mica tape and an inner sheath formed by crossed weaving. The inner sheath is wrapped in an outer sheath. A filling layer is disposed between the cable core and the second mica tape. The flexible cable has simple structure, a good tensile capability, a warp resistant capability, and a long service life and is easy to bend. The design of the composite fireproof layer and the second mica tape provides double-layer protection resistant to high temperature for the cable, effectively enhances the capability resistant to high temperature of the cable, and guarantees the using security of the cable suffering from high temperature burning.
Description
Technical field
The utility model relates to the electric wire field, is specially the high temperature resistant warp resistance flexible cable of a kind of tensile type.
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 subject to the calcination of flame; cause cable can not work because of short circuit, and the resistance to tension of common cable and anti-twist scarce capacity, be difficult for bending; Tensile, distortion and bending affect easy deformed damaged, cause shorten the useful life of cable.
The utility model content
The purpose of this utility model provides the high temperature resistant warp resistance flexible cable of a kind of tensile type, not good to solve cable resistance to elevated temperatures traditional in the prior art, cause easily cable short circuit and cisco unity malfunction when being subjected to the flame calcination, and resistance to tension and anti-twist scarce capacity, be difficult for bending, the problem that useful life is short.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of tensile type is 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 the first mica tape, fire-resistant inorganic short fiber adhesive-layer and lapping layer from inside to outside, several insulated wire cores and the stranded rear formation cable core of reinforcement steel core, described cable core is coated with the inner sheath that the second mica tape and interlacing consist of outward successively, described inner sheath is coated with oversheath, is provided with packed layer between described cable core and the second mica tape.
The high temperature resistant warp resistance flexible cable of described a kind of tensile type is characterized in that: described fire-resistant inorganic short fiber adhesive-layer adopts polycrystal alumina or polycrystalline mullite short fiber to make.
The high temperature resistant warp resistance flexible cable of described a kind of tensile type is characterized in that: described glide lamella is the macromolecule material film layer of low-friction coefficient.
The high temperature resistant warp resistance flexible cable of described a kind of tensile type 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 the second mica tape, for cable provides double-deck high temperature resistant protection, has effectively promoted the resistance to elevated temperatures of cable, has guaranteed the use safety of cable when being subjected to high temperature sintering; Employing is in the design of insulating barrier outer cladding glide lamella, so that have good slipping property between each insulated wire cores, convenient bending; Adopt the design stranded with strengthening steel core of several insulated wire cores, effectively promoted the resistance to tension of cable, and the design of inner sheath employing interlacing, the interlacing structure has larger extending space, effectively promote the anti-twist ability of cable, prolonged the useful life of cable.
