Abstract
The utility model discloses an anti-dragging and double-shielding cable for aluminum alloy conductors, comprising aluminum alloy conductors, and a belting layer, an inner shielding layer, an insulation layer, an outer shielding layer, and a protection sleeve, with the latter five coating the aluminum alloy conductor in order. Four sets of aluminum alloy conductors are provided, and are uniformly disposed in the belting layer. The center of the belting layer is provided with a ground wire core. The internal part of the insulation layer is provided with three drainage wires. A metal layer is disposed between the outer shielding layer and the protection sleeve, and is formed in a manner that high-density annealed steel wire coats and encircles low-smoke and halogen-free polyolefin flame retardation material. The anti-dragging and double-shielding cable for aluminum alloy conductors is advantageous in that the shielding performance and the conductive performance of the cable are good; the cable can be widely applied in fields like power generation, metallurgy, petrochemical industry, and others; the cable is capable of resisting dragging, oil, corrosion and high temperature, and is low in producing cost.
Description
Technical field
The utility model belongs to field of cables, relates in particular to the anti-screened cable that pulls of a kind of aluminium alloy conductor.
Background technology
At present, along with socioeconomic development, electric wire consumption increases rapidly, and the quality requirement of cable is also constantly improved.Such as the cable using in the fields such as field such as generating, metallurgy, chemical petroleum, high temperature resistant to cable, acid and alkali-resistance, anti-oxidant, anti-pulling, the requirement of the aspects such as oil resistant and shielding properties is all high especially.The manufacturing cost of same cable can not be ignored, general cable conductor adopts copper manufacture more, internal copper resource worsening shortages and copper cost are relatively high, only meet the manufacture of cable and use many-sided requirement, just can better meet the actual service condition of cable.
Utility model content
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide one, and to have electric conductivity excellent, the anti-screened cable that pulls of aluminium alloy conductor of advantages of good shielding performance advantage.
The utility model takes following technical scheme to realize: the anti-screened cable that pulls of a kind of aluminium alloy conductor, it is mainly by aluminium alloy conductor and is wrapped in successively the belting layer outside aluminium alloy conductor, internal shield, insulating barrier, outer shielding layer and protective sleeve composition, described aluminium alloy conductor is four groups, evenly be extruded in described belting layer inside, described belting layer center is provided with a ground connection core, described insulating barrier inside is provided with three drainage threads, between described outer shielding layer and described protective sleeve, be provided with metal level, described metal level holds low-smoke halogen-free polyolefin fire proofing by high density annealed wire and forms.
Described ground connection core is by multiply nickel plating aluminium wire outsourcing annealed wire, stack stranded forming to the right up and down.
Described internal shield is to be formed by the braiding of albronze silk outsourcing annealed wire, and described outer shielding layer is tinned copper wire mesh grid.
Described protection jacket layer is made up of steel-tape armouring polytetrafluoroethylmaterial material.
The utlity model has in sum following beneficial effect: the utlity model has good shielding properties, conduct electricity very well, be widely used in the fields such as generating, metallurgy, chemical petroleum, anti-pulling, oil resistance anticorrosion erosion also possesses the advantages such as high temperature resistant, low cost of manufacture simultaneously.
