Abstract

The utility model discloses a warp-resistant, fireproof and mouse-prevention power cable. The cable comprises a plurality of conductors, and a composite insulating layer and a mica tape are successively wrapped outside each conductor, so that insulating cores are formed. Each composite insulating layer, from inside the outside, successively includes a taped semi-conduction nylon belt, a polyvinyl chloride insulating layer and a semi-conduction shielding layer. The insulating cores are intertwisted to form a cable core, and a non-woven fabric taped belt is wrapped outside the cable core. An inner sheath formed by intersected braiding is wrapped outside the taped belt, 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 taped belt. The power cable has a simple structure, exhibits good insulating and warp-resistant performance, is prevented from being bitten by mice and is long in service life. Through a design of the mica tapes outside the composite insulating layers, the power cable is effectively improved in terms of fireproof performance, can be burnt by flames under a high temperature for a long period of time and is guaranteed to be safe to use.

Description

The fire-resistant protection against rodents power 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 power 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 existing power insulating performance of cable is not good; fire resistance is relatively poor; 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, have potential safety hazard, and common power cable is bitten by mouse easily; anti-twist scarce capacity is twisted the useful life that influences easy shortening cable for a long time.
The utility model content
The purpose of this utility model provides the fire-resistant protection against rodents power cable of a kind of warp resistance, traditional power cable is bitten by mouse easily in the prior art to solve, insulation property are not good, fire resistance is relatively poor, the warp resistance scarce capacity, be subjected to distortion to influence easy shortening cable useful life for a long time, cable was influenced by the flame calcination easily and causes decreasing insulating when fire took place, and had the problem of potential safety hazard.
For achieving the above object, the technical solution adopted in the utility model is:
The fire-resistant protection against rodents power cable of a kind of warp resistance, include the array conductor, it is characterized in that: every group of conductor all is coated with composite insulation layer and mica tape outward successively, and formation insulated wire cores, described composite insulation layer is followed successively by wrapped semiconductive nylon tape from inside to outside, polyvinyl chloride insulation layer and semiconductive shielding layer, the stranded formation cable core of several insulated wire cores, described cable core is coated with the nonwoven fabrics twining package tape, described twining package 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 twining package tape.
The fire-resistant protection against rodents power cable of described a kind of warp resistance is characterized in that: described oversheath adopts flame-proof polyvinyl chloride to make.
The beneficial effects of the utility model are:
The utility model is simple in structure, adopts the design of composite insulation layer, has promoted the insulation property of power cable effectively; 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 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 composite insulation layer, promoted the fire-resistance property of cable effectively, can stand the thermal-flame calcination for a long time, has ensured the safe in utilization of power 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 power cable of a kind of warp resistance, include array conductor 1, every group of conductor 1 outer composite insulation layer and mica tape 5 of all being coated with successively, and formation insulated wire cores, composite insulation layer is followed successively by wrapped semiconductive nylon tape 2 from inside to outside, polyvinyl chloride insulation layer 3 and semiconductive shielding layer 4, the stranded formation cable core of several insulated wire cores, cable core is coated with nonwoven fabrics twining package tape 6, twining package 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 twining package tape 6.Oversheath 9 adopts flame-proof polyvinyl chloride to make.
