Abstract
The utility model discloses a warp-resistant, fireproof, mouse-prevention and tensile cable. The cable comprises a plurality of conductors, and a mica tape, a taped layer and an insulating layer are successively wrapped outside each conductor, so that insulating cores are formed. The insulating cores and reinforced steel cores are intertwisted to form a cable core. A glass fiber tape is wrapped outside the cable core, an inner sheath formed by intersected braiding is wrapped outside the glass fiber tape, and a nylon protective layer and an outer sheath are successively wrapped outside the inner sheath. A filling layer is disposed between the cable core and the glass fiber tape. The cable of the utility model has a simple structure, exhibits excellent warp-resistant and tensile properties, is effectively prevented from being bitten by mice and is prolonged in terms of the service life. Through a design of the mica tape outside each conductor, the cable is effectively promoted in terms of fireproof performance and is guaranteed to be safe to use.
Description
Technical field
The utility model relates to the electric wire field, is specially the fire-resistant protection against rodents tension of a kind of warp resistance cable.
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; be difficult to isolated flame, so flame these protective layers that are easy to ablate, make cable directly be subjected to the calcination of flame; cause cable can not work because of short circuit; and common cable is bitten by mouse easily, and anti-twist ability and resistance to tension deficiency are twisted the useful life that also can shorten cable with stretch effects for a long time.
The utility model content
The purpose of this utility model provides the fire-resistant protection against rodents tension of a kind of warp resistance cable, traditional cable is bitten by mouse easily in the prior art to solve, anti-twist ability and resistance to tension deficiency, fire resistance is not good, be subjected to distortion after long-time the use easily, stretch, and flame calcination influence and the problem that causes cable to shorten and be short-circuited useful life.
For achieving the above object, the technical solution adopted in the utility model is:
The fire-resistant protection against rodents tension of a kind of warp resistance cable, 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, several insulated wire cores constitute cable core with the stranded back of reinforcement steel core, and described cable core is coated with glass fiber tape, and 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 tension of described a kind of warp resistance cable is characterized in that: described conductor is zinc-plated soft copper conductor.
The fire-resistant protection against rodents tension of described a kind of warp resistance cable is characterized in that: described oversheath adopts silicon 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; 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; Adopt the nylon overcoat design preferably of hardness and surface flatness, prevented that effectively cable from suffering biting of mouse; Employing is provided with the design of mica tape outside conductor, promoted the fire-resistance property of cable effectively, can stand nearly 800 ℃ flame temperature for a long time, 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 tension of a kind of warp resistance cable, 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 constitute insulated wire cores, several insulated wire cores constitute cable core with reinforcement steel core 5 stranded backs, cable core is coated with glass fiber tape 6, glass fiber tape 6 is coated with the inner sheath 7 that interlacing constitutes, and is coated with nylon overcoat 8 and oversheath 9 successively outside the inner sheath 7, is provided with packed layer 10 between cable core and the glass fiber tape 6.
Conductor 1 is zinc-plated soft copper conductor, and oversheath 9 adopts silicon rubber to make.
