Abstract

The utility model discloses a warp resistant fireproof tensile flexible cable, comprising a plurality of groups of conductor, wherein each group of conductor is orderly wrapped with a mica tape, a lapped wrapping layer and an insulating layer to form an insulating wire core, each insulating wire core is wrapped with a slippage layer, a plurality of insulating wire cores and a reinforcing steel core are intertwisted to form a cable core, the cable core is wrapped with a glass fiber tape, the glass fiber tape is wrapped with an inner sheath formed through cross weaving, the inner sheath is wrapped with an outer sheath, and the gap between the cable core and the glass fiber tape is filled with a filling layer. The warp resistant fireproof tensile flexible cable is simple in structure, good in warp resistance, tension resistance and fireproof property, good in slippage property among various insulating wire cores, convenient to bend, and uneasy to deform, enables the service life of the cable to be prolonged, and ensures the use safety of the cable.

Description

The fire-resistant tension flexible cable of a kind of warp resistance

Technical field

The utility model relates to the electric wire field, is specially the fire-resistant tension flexible cable of a kind of warp resistance.

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 ability of common cable and resistance to tension deficiency, 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 the fire-resistant tension flexible cable of a kind of warp resistance, not enough to solve the anti-twist ability of cable traditional in the prior art and resistance to tension, 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:

The fire-resistant tension flexible cable of a kind of warp resistance, include the array conductor, it is characterized in that: every group of conductor all is coated with mica tape, lapping layer and insulating barrier outward successively, and formation insulated wire cores, every eradication edge core is coated with glide lamella, several insulated wire cores and the stranded rear formation cable core of reinforcement steel core, 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.

The fire-resistant tension flexible cable of described a kind of warp resistance is characterized in that: described glide lamella is the macromolecule material film layer of low-friction coefficient.

The fire-resistant tension flexible cable of described a kind of warp resistance 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; Employing arranges the design of mica tape outside conductor, effectively promoted the fire-resistance property of cable; Adopt the design stranded with strengthening steel core of several insulated wire cores, effectively promoted the resistance to tension of cable; 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, has ensured the use safety of cable.
