Abstract

The utility model discloses a tensile, fireproof, flame-retardant and termite-resistant flexible cable. The cable comprises a plurality of conductors, and a composite fireproof layer, an insulating layer and a slip layer are successively wrapped outside each conductor, so that insulating cores are formed. Each composite fireproof layer successively comprises, from inside to outside, a first mica tape, a fireproof inorganic short fiber viscose glue layer and a taped layer. The insulating cores and the reinforced steel cores are intertwisted to form a cable core. A second mica tape is wrapped outside the cable core. An inner sheath, a nylon protective layer and an outer sheath are successively wrapped outside the second mica tape. A filling layer is arranged between the cable core and the second mica tape. The cable of the utility model has a simple structure, exhibits good tensile performance, is equipped with the composite fireproof layers and the second mica tape so as to be protected by two fireproof layers, is effectively promoted in terms of fireproof performance and is effectively prevented from being bitten by termites. Moreover, the insulating cores exhibit excellent slip performance among each other, so that the cable is convenient to bend, is not liable to deform and is prolonged in terms of the service life.

Description

The termite-proof flexible cable of a kind of tensile type fire resistant flame retardant
Technical field
The utility model relates to the electric wire field, is specially the termite-proof flexible cable of a kind of tensile type fire resistant flame retardant.
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 structure of thermal insulation difference, not flame resistant calcination.Therefore; when breaking out of fire, the not flame resistant baking of this class cable is difficult to isolated flame; therefore flame these protective layers that are easy to ablate; make cable directly be subjected to the calcination of flame, cause cable can not work, and common cable is bitten easily by termite because of short circuit; the resistance to tension deficiency; difficult bending is stretched and bending influences easy deformation, causes shorten the useful life of cable.
The utility model content
The purpose of this utility model provides a kind of fire resistant flame retardant cable, not good to solve cable fire resistance traditional in the prior art, cause cable short circuit easily and cisco unity malfunction when being subjected to the flame calcination, and bitten by termite easily, the resistance to tension deficiency, difficult bending is stretched and bending influences easy deformation, the problem that useful life is short.
For achieving the above object, the technical solution adopted in the utility model is:
The termite-proof flexible cable of a kind of tensile type fire resistant flame retardant, include the array conductor, it is characterized in that: every group of conductor all is coated with the composite fire layer outward successively, insulating barrier and glide lamella, and formation insulated wire cores, described composite fire layer is followed successively by first mica tape from inside to outside, fire-resistant inorganic short fiber adhesive-layer and lapping layer, several insulated wire cores constitute cable core with the stranded back of reinforcement steel core, described cable core is coated with second mica tape, described second mica tape is coated with inner sheath outward successively, nylon overcoat and oversheath are provided with packed layer between the described cable core and second mica tape.
The termite-proof flexible cable of described a kind of tensile type fire resistant flame retardant is characterized in that: described fire-resistant inorganic short fiber adhesive-layer adopts polycrystal alumina or polycrystalline mullite short fiber to make.
The termite-proof flexible cable of described a kind of tensile type fire resistant flame retardant is characterized in that: described glide lamella is the macromolecule material film layer of low-friction coefficient.
The termite-proof flexible cable of described a kind of tensile type fire resistant flame retardant 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 the composite fire layer and second mica tape, for cable provides double-deck refractory protection, promoted the fire resistance of cable effectively, has guaranteed cable safe in utilization when being subjected to high temperature sintering; Employing coats the design of glide lamella outside insulating barrier, make to have good slipping property between each insulated wire cores, convenient bending, and not yielding; Adopt the nylon overcoat design preferably of hardness and surface flatness, prevented that effectively cable from suffering biting of termite; Adopt several insulated wire cores and strengthen the stranded design of steel core, promoted the resistance to tension of cable effectively, prolonged the useful life of cable.
