Utility model content
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide the corrosion-resistant moistureproof power cable of a kind of insulation.
The utility model is taked following technical scheme to realize: the corrosion-resistant moistureproof power cable of a kind of insulation, and it comprises cable body, and described cable body comprises conductor, insulating barrier, screen and oversheath, and described cable body inside is provided with multiple conductor; Described conductor outer wrapping one deck protective sleeve; Described protective sleeve and conductor form cable core jointly; Described cable core be outside equipped with multiple aluminium alloy flexible pipe and cable core tangent; One deck insulating barrier is set outside described cable core; Described insulating barrier, between cable core and aluminium alloy flexible pipe, gap portion is provided with packed layer; One deck screen is extruded outside described insulating barrier; Described screen is extruded with block water wrapped belt and metal armor layers from inside to outside respectively; The described wrapped belt inside that blocks water is provided with multiple drainage thread; Described metal armor layers closely extrudes one deck corrosion-resistant coating outward; One deck oversheath is extruded outside described corrosion-resistant coating.
Above-mentioned one insulate corrosion-resistant moistureproof power cable, and to be that multiply tinned copper wire is stranded form described conductor.
Above-mentioned one insulate corrosion-resistant moistureproof power cable, and described insulating barrier is inorganic thin film, PVC coating or rubber are made.
Above-mentioned one insulate corrosion-resistant moistureproof power cable, and described packed layer is that non-wet materials polypropylene mesh split fibre is made.
Above-mentioned one insulate corrosion-resistant moistureproof power cable, and described insulating barrier, screen are identical with the twining package tape thickness that blocks water.

The utility model has following beneficial effect in sum: the utility model cable has the advantages such as the good and long service life of reasonable in design, moisture effect, the described twining package tape that blocks water not only can play the effect of radial waterproof and the infiltration of anti-chemical solution, can also play cable and run the cushioning effect of expanding with heat and contract with cold in overshoot.
Accompanying drawing explanation
Fig. 1 is the utility model cross-sectional structure schematic diagram;
Wherein: 1, cable body; 2, conductor; 3, protective sleeve; 4, packed layer; 5, aluminium alloy flexible pipe; 6, insulating barrier; 7, screen; 8, block water wrapped belt; 9, drainage thread; 10, metal armor layers; 11, corrosion-resistant coating; 12, oversheath.
Embodiment
As shown in Figure 1, the corrosion-resistant moistureproof power cable of a kind of insulation, it comprises cable body 1, and described cable body 1 comprises conductor 2, insulating barrier 6, screen 7 and oversheath 12, and described cable body 1 inside is provided with multiple conductor 2; Described conductor 2 outer wrapping one deck protective sleeve 3; Described protective sleeve 3 and conductor 2 form cable core jointly; It is tangent with cable core that described cable core is outside equipped with multiple aluminium alloy flexible pipe 5; One deck insulating barrier 6 is set outside described cable core; Described insulating barrier 6, between cable core and aluminium alloy flexible pipe 5, gap portion is provided with packed layer 4; One deck screen 7 is extruded outside described insulating barrier 6; Described screen 7 is extruded with block water wrapped belt 8 and metal armor layers 10 from inside to outside respectively; Described wrapped belt 8 inside that blocks water is provided with multiple drainage thread 9; Described metal armor layers 10 is outer closely extrudes one deck corrosion-resistant coating 11; One deck oversheath 12 is extruded outside described corrosion-resistant coating 11.
Described conductor 2 forms for multiply tinned copper wire is stranded, thus makes conductor 2 have good corrosion resistance, and has the advantages such as large, the high temperature resistant and strong anti-oxidation of loaded current; The outer protective sleeve 3 arranged of described conductor 2 effectively protection conductor 2, prevents conductor 2 because there is situation about rupturing by external force; Described packed layer 4 is made for non-wet materials polypropylene mesh split fibre, conductor 2 effectively can be protected can not to bend because being subject to external force and occur situation about losing, and improves twisting resistance and the crushing resistance of cable, effectively protects cable; Described aluminium alloy flexible pipe 5 has good stretch-resistance, substantially increases the elasticity of cable body 1, makes it under various angle, also there will not be fracture; Described insulating barrier 6 is made for inorganic thin film, PVC coating or rubber, effectively raises the insulation effect of cable; Described screen 7 not only increases the ability of the shielded signal of cable, and effectively adds the useful life of cable and water-fast and weatherability; The described wrapped belt 8 that blocks water not only can play the effect of radial waterproof and the infiltration of anti-chemical solution, can also play cable and run the cushioning effect of expanding with heat and contract with cold in overshoot; The drainage thread 9 that described lapping layer 8 inside that blocks water is arranged is conducive to the grounding of cable, ensure that the continuity of screen 7; Described metal armor layers 10 can not only improve the shielding properties of cable further, also can protect insulating barrier 6 and the conductor 2 of cable inside, greatly reduce the moisture absorption of cable and the performance of oxidation, ensures the long-term shield effectiveness efficiently of cable; Described corrosion-resistant coating 11 can prevent acid-base solution to the corrosion of cable, substantially prolongs the useful life of cable; Described oversheath 12 adopts butyronitrile polyvinyl chloride elastomeric material to make, thus higher temperature can be born, and harmful Substances Pollution environment can not be produced in hot environment, thus make its environmental-protecting performance more excellent, meet present the advocated environmental protection concept of people.
The above is the utility model embodiment, therefore all equivalences done according to structure, feature and the principle described in the utility model application range change or modify, and are included in the utility model patent claim.
