Abstract
The utility model discloses a tension-and-torsion-resistant fireproof anti-rat power cable. The power cable comprises multiple conductors, and each conductor is successively wrapped in a composite insulation layer and a mica tape to form an insulating conductor core, wherein the composite insulation layer successively includes a semi-conductive nylon tape, a polyvinyl chloride insulation layer and a semi-conductive shielding layer from inside to outside; the multiple insulating cores are stranded with strengthening steel cores to form a cable core; the cable core is wrapped in non-woven fabric taped covering; the taped covering is wrapped in a cross-braided inner sheath; the inner sheath is successively wrapped in a nylon protective and an oversheath layer; and a filling layer is arranged between the cable core and the oversheath layer. The tension-and-torsion-resistant fireproof anti-rat power cable has better insulation performance, torsion resistance and tension resistance; the cable is prevented from being bitten by the rats; service life of the cable is long; the mica tapes are arranged outside the composite insulation layers to effectively improve fireproof performance of the cable; the cable can bear long-term high-temperature firing; and use safety of the power cable is ensured.
Description
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 tensile type 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 and has potential safety hazard; anti-twist ability and resistance to tension deficiency are twisted the useful life that shortens cable with stretch effects easily 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 tensile type 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, warp resistance ability and resistance to tension deficiency, be subjected to distortion, stretch effects to shorten cable useful life easily 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 tensile type 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, several insulated wire cores constitute cable core with the stranded back of reinforcement steel core, 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 tensile type 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 several insulated wire cores and strengthen the stranded design of steel core, promoted the resistance to tension 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 tensile type 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, several insulated wire cores constitute cable cores with reinforcement steel core 6 stranded backs, cable core is coated with nonwoven fabrics twining package tape 7, twining package tape 7 is coated with the inner sheath 8 that interlacing constitutes, be coated with nylon overcoat 9 and oversheath 10 successively outside the inner sheath 8, be provided with packed layer 11 between cable core and the twining package tape 7.Oversheath 10 adopts flame-proof polyvinyl chloride to make.
Claims (2)
