Abstract
The invention discloses a dragging-resistant double-shielded cable with aluminum alloy conductors. The cable is mainly composed of the aluminum alloy conductors, a taping layer, an inner shielding layer, an insulating layer, an outer shielding layer and a protective sleeve. The number of the aluminum alloy conductors is four. The four aluminum alloy conductors are evenly distributed in the taping layer in an extruded mode. A grounded cable core is arranged in the center of the taping layer. Three current guiding wires are arranged in the insulating layer. A metal layer is arranged between the outer shielding layer and the protective sleeve. The metal layer is formed by wrapping around low-smoke halogen-free polyolefin flame retardant materials through high-density annealed wires. The cable has high shielding performance and good conductivity, thereby being widely applied to the fields of power generation, metallurgy, chemical engineering, petroleum and the like. Meanwhile, the cable further has the advantages of being resistant to dragging, resistant to oil and high temperature, capable of preventing corrosion, low in manufacturing cost and the like.
Description
Technical field
The invention belongs to field of cables, relate 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.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide one, to have electric conductivity excellent, the anti-screened cable that pulls of aluminium alloy conductor of advantages of good shielding performance advantage.
The present invention 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 present invention has following beneficial effect in sum: the present invention has good shielding properties, conducts electricity very well, and is widely used in the fields such as generating, metallurgy, chemical petroleum, anti-pulling, and oil resistance anticorrosion erosion also possesses the advantages such as high temperature resistant, low cost of manufacture simultaneously.

embodiment
As shown in Figure 1, the anti-screened cable that pulls of a kind of aluminium alloy conductor, it is mainly by aluminium alloy conductor 1 and is wrapped in successively the belting layer 3 outside aluminium alloy conductor 1, internal shield 5, insulating barrier 6, outer shielding layer 7 and protective sleeve 9 form, described aluminium alloy conductor 1 is four groups, evenly be extruded in described belting layer 3 inside, described belting layer 3 centers are provided with a ground connection core 2, described insulating barrier 6 inside are provided with three drainage threads 4, between described outer shielding layer 7 and described protective sleeve cover 9, be provided with metal level 8, described metal level 8 holds low-smoke halogen-free polyolefin fire proofing by high density annealed wire and forms.
Described ground connection core 2 is by multiply nickel plating aluminium wire outsourcing annealed wire, stack stranded forming to the right up and down.
Described internal shield 5 is to be formed by the braiding of albronze silk outsourcing annealed wire, and described outer shielding layer 7 is tinned copper wire mesh grids.
Described protection jacket layer 9 is made up of steel-tape armouring polytetrafluoroethylmaterial material.
The permission bending radius of this cable is the outside diameter of cable 12 times; Cable permission work maximum temperature is 95 DEG C; The shielding rejection coefficient of this cable is less than 0.7; Can stand to exchange 50HZ, 3.5Kv/5min voltage and not breakdown.
The above is embodiments of the invention, and the equivalence of doing according to structure, feature and principle described in the present patent application scope therefore all changes or modifies, and is included in patent claim of the present invention.
