Abstract

The utility model discloses a torsion-resistant fireproof anti-rat flexible cable. The cable comprises multiple conductors, and each conductor is successively wrapped in a mica tape, a taped covering and an insulating layer to form an insulating core; each insulating core is wrapped in a slip layer; the multiple insulating cores are stranded to form a cable core; the cable core is wrapped in a glass fiber tape; the glass fiber tape is wrapped in a cross-braided inner sheath; the inner sheath is successively wrapped in a nylon protective layer and an oversheath; and a filing layer is arranged between the cable core and the glass fiber tape. The torsion-resistant fireproof anti-rat flexible cable is simple in structure, has better torsion-resistant capability and fireproof characteristics, possesses good slipping property among the insulating cores, is convenient to bend and not easy to deform, is effectively prevented from being bitten by the rats, prolongs service life, and ensures use safety.

Description

The fire-resistant protection against rodents flexible cable of a kind of warp resistance
Technical field
The utility model relates to the electric wire field, is specially the fire-resistant protection against rodents 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 structure flame resistant not of thermal insulation difference.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 mouse because of short circuit; anti-twist scarce capacity; be difficult for bending, be subjected to distortion, bending to influence easily and deform, cause shorten the useful life of cable.
The utility model content
The purpose of this utility model provides the fire-resistant protection against rodents flexible cable of a kind of warp resistance, traditional cable is bitten by mouse easily in the prior art to solve, anti-twist scarce capacity, be difficult for bending, fire resistance is not good, is twisted, bends the problem that causes cable shortening in useful life and be short-circuited with the flame calcination that influences during use easily.
For achieving the above object, the technical solution adopted in the utility model is:
The fire-resistant protection against rodents 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, 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 constitutes, described inner sheath is coated with nylon overcoat and oversheath outward successively, is provided with packed layer between described cable core and the glass fiber tape.
The fire-resistant protection against rodents 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 protection against rodents 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 bigger extending space, has promoted the anti-twist ability of cable effectively; Employing is provided with the design of mica tape outside conductor, promoted the fire-resistance property of cable effectively; Adopt the nylon overcoat design preferably of hardness and surface flatness, prevented that effectively cable from suffering biting of mouse; Employing coats the design of glide lamella outside insulated wire cores, make to have good slipping property between each insulated wire cores, and convenience bends, and not yielding, has prolonged the useful life of cable, has ensured the safe in utilization of cable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the fire-resistant protection against rodents 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 formation 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, glass fiber tape 6 is coated with the inner sheath 7 that interlacing constitutes, be coated with nylon overcoat 8 and oversheath 9 successively outside the inner sheath 7, be provided with packed layer 10 between cable core and the glass fiber tape 6.
Glide lamella 5 is the macromolecule material film layer of low-friction coefficient, and oversheath 9 adopts acrylonitrile-butadiene rubber to make.
