Abstract
The utility model discloses a tensile fireproof power cable comprising a plurality of conductors, each of which is sequentially wrapped by a composite insulation layer and a mica tape to form an insulation wire core. Each of the composite insulation layers is sequentially, from inside to outside, wrapped by a semiconductor nylon band, a polyvinyl chloride insulation layer, and a semi-conductive shielding layer in a coiled manner. The plurality of insulation wire cores and reinforced steel cores are intertwisted together to form a cable core, which is wrapped by a non-woven fabric wrapping tape. The wrapping tape is wrapped by a sheath layer, and a filling layer is disposed between the cable core and the wrapping tape. The utility model is advantageous in that the structure is simple, the design of the composite insulation layer is adopted, therefore the insulation performance of the power cable can be effectively improved; the design of intertwisting the plurality of the insulation wire cores and the reinforced steel cores is adopted, therefore the tensile ability of the cable can be effectively improved; the design of arranging the mica tape on the outer side of each of the composite insulation layers is adopted, therefore the fireproof performance of the cable can be effectively improved, the cable can bear the long-time burning of the high temperature fire, and the use safety of the power cable can be guaranteed.
Description
Technical field
The utility model relates to the electric wire field, is specially a kind of tension fireproof power 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.Existing power cable insulation performance 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, so flame these protective layers that are easy to ablate; make cable directly be subject to the calcination of flame; have potential safety hazard, and the resistance to tension of power cable is not enough, the useful life of cable is easily shortened in long-time Tensile impact.
The utility model content
The purpose of this utility model provides a kind of tension fireproof power cable, not good to solve power cable insulation performance traditional in the prior art, fire resistance is relatively poor, resistance to tension is not enough, cable useful life is easily shortened in long-time Tensile impact, cable was affected by the flame calcination easily and causes decreasing insulating when fire occured, and had the problem of potential safety hazard.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of tension fireproof power cable, 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, polyvinyl chloride insulation layer and semiconductive shielding layer from inside to outside, several insulated wire cores and the stranded rear formation cable core of reinforcement steel core, described cable core is coated with the nonwoven fabrics twining package tape, described twining package tape is coated with restrictive coating, is provided with packed layer between described cable core and the twining package tape.
Described a kind of tension fireproof power cable is characterized in that: described restrictive coating 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 effectively promoted the insulation property of power cable; Adopt the design stranded with strengthening steel core of several insulated wire cores, effectively promoted the resistance to tension of cable; Employing arranges the design of mica tape outside composite insulation layer, effectively promoted the fire-resistance property of cable, can stand for a long time the thermal-flame calcination, has ensured the use safety of power cable.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of tension fireproof power cable, include array conductor 1, every group of conductor 1 outer composite insulation layer and mica tape 5 of all being coated with successively, and consist of insulated wire cores, composite insulation layer is followed successively by wrapped semiconductive nylon tape 2, polyvinyl chloride insulation layer 3 and semiconductive shielding layer 4 from inside to outside, several insulated wire cores and reinforcement steel core 6 stranded rear formation cable cores, cable core is coated with nonwoven fabrics twining package tape 7, and twining package tape 7 is coated with restrictive coating 8, is provided with packed layer 9 between cable core and the twining package tape 7.Restrictive coating 8 adopts flame-proof polyvinyl chloride to make.
