Abstract
The utility model discloses a warp resistant fireproof 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 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 flexible cable is simple in structure, good in warp 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
Technical field
The utility model relates to the electric wire field, is specially the fire-resistant 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 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 the fire-resistant flexible cable of a kind of warp resistance, 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:
The fire-resistant 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 the formation insulated wire cores, 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, and described inner sheath is coated with oversheath, is provided with packed layer between described cable core and the glass fiber tape.
The fire-resistant 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 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; 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.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the fire-resistant flexible cable of a kind of warp resistance, include array conductor 1, every group of conductor 1 outer mica tape 2, lapping layer 3 and insulating barrier 4 of all being coated with successively, and consist of insulated wire cores, every eradication edge core is coated with glide lamella 5, the stranded formation cable core of several insulated wire cores, cable core is coated with glass fiber tape 6, and glass fiber tape 6 is coated with the inner sheath 7 that interlacing consists of, inner sheath 7 is coated with oversheath 8, is provided with packed layer 9 between cable core and the glass fiber tape 6.
Glide lamella 5 is the macromolecule material film layer of low-friction coefficient, and oversheath 8 adopts acrylonitrile-butadiene rubber to make.
