Abstract
The utility model discloses an antistatic stretch-proofing cable, which is composed of a polyperfluorinated ethylene propylene outer sheath, a tinned copper wire braided shielding layer and a cable core, wherein the cable core is formed by extruding a fluororubber insulating layer on three power wire cores; each power wire core is formed by extruding a ceramic powder polyvinyl chloride inner insulating layer on three insulated wire cores; drainage wire cores are arranged in the insulating wire cores; a tensile-resistant steel wire rope is arranged among the three power wire cores; and the cable core is sequentially wrapped with the tinned copper wire braided shielding layer and the polyperfluorinated ethylene propylene outer sheath. The antistatic stretch-proofing cable can be used for high-voltage line and power line laying cables, has excellent electrical performance and excellent anti-interference performance, is antistatic, and is high in structural strength.
Description
Technical field
The utility model relates to field of cables, relates in particular to a kind of antistatic stretch-proof cable.
Background technology
At present, phase conductor, overhead ground wire and the power cable of optical cable and power transmission line are complex as a whole to structure, it is optical cable, this structure has ground wire and the dual-use function of communicating by letter concurrently, and power department is for improving the security reliability of optical cable transmission circuit, and preferably electric power special optical cable is laid along high-voltage line power line, but common cable can not be effectively anti-interference, and tensile strength is low, a little less than antistatic performance, main cause is that the structure and material of cable designs, selects also unreasonable.Therefore, need to provide a kind of new technical scheme to solve the problems referred to above.
Utility model content
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of antistatic stretch-proof cable.
The utility model takes following technical scheme to realize: a kind of antistatic stretch-proof cable, it is comprised of perfluoroethylene-propylene oversheath, tinned copper wire woven shield and cable core, and described cable core is by fluorubber insulating barrier, to extrude three power cores to form; Described power core is by ceramic powders polyvinyl chloride internal shield, to extrude three insulated wire cores to form; In described insulated wire cores, be provided with drainage core; In the middle of described three power cores, be provided with tension steel wire rope; Described cable core is coated with tinned copper wire woven shield and perfluoroethylene-propylene oversheath outward successively.
Described insulated wire cores is to be formed by the wrapped aluminium alloy conductor of polyvinyl chloride insulation layer.
The utlity model has in sum following beneficial effect: this cable is applicable to high-voltage line power line cable laying, superior electrical property, interference free performance are excellent, and have antistatic, the feature that structural strength is high.
Accompanying drawing explanation
Fig. 1 is the utility model cross-sectional structure schematic diagram;
Wherein: 1, perfluoroethylene-propylene oversheath; 2, tinned copper wire woven shield; 3, fluorubber insulating barrier; 4, ceramic powders polyvinyl chloride internal shield; 5, drainage core; 6, aluminium alloy conductor; 7, polyvinyl chloride insulation layer; 8, tension steel wire rope.
Embodiment
As shown in Figure 1, a kind of antistatic stretch-proof cable, it is comprised of perfluoroethylene-propylene oversheath 1, tinned copper wire woven shield 2 and cable core, and described cable core is by fluorubber insulating barrier 3, to extrude three power cores to form; Described power core is by ceramic powders polyvinyl chloride internal shield 4, to extrude three insulated wire cores to form; In described insulated wire cores, be provided with drainage core 5; In the middle of described three power cores, be provided with tension steel wire rope 8; Described cable core is coated with tinned copper wire woven shield 2 and perfluoroethylene-propylene oversheath 1 outward successively.
Described insulated wire cores is to be formed by the wrapped aluminium alloy conductor 6 of polyvinyl chloride insulation layer 7.
Compared with the prior art, the utility model beneficial effect is embodied in: this cable is applicable to high-voltage line power line cable laying, and superior electrical property, interference free performance are excellent, and have antistatic, the feature that structural strength is high.
The above is the utility model embodiment, and the equivalence of doing according to structure, feature and principle described in the utility model application range therefore all changes or modifies, and is included in the utility model patent claim.
