Abstract
The utility model discloses and in a kind of wind power generation distortion resistant, press soft power cable, comprise 3 main insulation cores and 3 ground cores, 3 main insulation cores are by being disposed with semiconducting rubber conductor shield, ethylene-propylene rubber insulated layer, strippable semi-conductive rubber insulation screen formation outside leading body and outside thereof; Three ground cores form by the semiconducting rubber screen in earthing conductor and outside thereof; 3 ground cores are placed in 3 main insulation core outsides and are twisted into together cable core, and cable core center adopts unvulcanised semiconducting rubber packing to form packed layer, and cable core is respectively equipped with ethylene-propylene rubber sheath and neoprene rubber external sheath layer outward.The warp resistance of the utility model conductor is superior, overall structure midium voltage cable local discharge test need to improve again the warp resistance of cable, the filling of cable, inner/outer sheath double-layer coextrusion technique are once extruded into an integral body, make cable there is excellent warp resistance performance and ageing resistace, meet the needs of high-power wind power generation.
Description
technical field:
The utility model relates to power cable, relates in particular in a kind of wind power generation distortion resistant and presses soft power cable, specifically for 12/20kV wind power generation distortion resistant, presses soft power cable.
background technology:
At present, wind power generation has been that installed capacity is the power generating industry of the 3rd share after thermoelectricity and water power in China, one of important field in Ye Shi China new forms of energy.1kV and the soft power cable of following warp resistance are widely used in wind turbine generator.
Along with high-power blower more than 2MW is being developed and tried out to wind-powered electricity generation industry, be characterized in that electricity that generally blower fan sends is transferred to lower-class line from cabin through tower bucket after need to directly boosting again, therefore designing and pressing soft power cable in warp resistance is vital to high-power blower.
utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide in a kind of wind power generation distortion resistant and presses soft power cable, meets the needs of high-power wind power generation.
The technical solution of the utility model is as follows:
In wind power generation distortion resistant, press soft power cable, comprise 3 main insulation cores and 3 ground cores, it is characterized in that: 3 described main insulation cores are by being disposed with semiconducting rubber conductor shield, ethylene-propylene rubber insulated layer, strippable semi-conductive rubber insulation screen formation outside leading body and outside thereof; Three described ground cores form by the semiconducting rubber screen in earthing conductor and outside thereof; 3 described ground cores are placed in 3 main insulation core outsides and are twisted into together cable core, and cable core center adopts unvulcanised semiconducting rubber packing to form packed layer, and cable core is respectively equipped with ethylene-propylene rubber sheath and neoprene rubber external sheath layer outward.
In described wind power generation distortion resistant, press soft power cable, it is characterized in that: described leading body adopts the zinc-plated soft copper conductor of 5 class, adopt regular stranded formation after first synnema.
In described wind power generation distortion resistant, press soft power cable, it is characterized in that: cable core is outer without filling, without twining package tape, and between cable core, gap, ethylene-propylene rubber sheath and neoprene rubber external sheath layer adopt double-layer coextrusion technique to be once extruded into an integral body.
The utility model has the advantages that:
1, cable conductor adopts 5 class multiply tinned copper conductors, adopts regular stranded structure after first synnema, has improved the warp resistance of cable conductor;
2, cable conductor adopts 3+3 structure, with the ground core of semi-conductive screen, is placed in metallic shield but also the ground connection that midium voltage cable had not only been made on main insulation core side, has not only met midium voltage cable local discharge test needs but also has improved the warp resistance of cable.
3, the filling of cable, inner/outer sheath adopt second the third glue rubber and neoprene rubber oversheath double-layer coextrusion technique to be once extruded into an integral body, make cable have excellent warp resistance performance and ageing resistace.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
embodiment:
Referring to accompanying drawing:
In wind power generation distortion resistant, press soft power cable, comprise 3 main insulation cores and 3 ground cores, 3 main insulation cores are by being disposed with semiconducting rubber conductor shield 2, ethylene-propylene rubber insulated layer 3, strippable semi-conductive rubber insulation screen 4 formations outside leading body 1 and outside thereof; Three ground cores form by the semiconducting rubber screen 6 in earthing conductor 5 and outside thereof; 3 ground cores are placed in 3 main insulation core outsides and are twisted into together cable core, and cable core center adopts unvulcanised semiconducting rubber packing to form packed layer 7, and cable core is respectively equipped with ethylene-propylene rubber sheath 8 and neoprene rubber external sheath layer 9 outward.
Leading body 1 adopts the zinc-plated soft copper conductor of 5 class, adopts regular stranded formation after first synnema, has improved the warp resistance of cable conductor.
Cable core is outer without filling, without twining package tape, and between cable core, gap, ethylene-propylene rubber sheath 8 and neoprene rubber external sheath layer 9 adopt double-layer coextrusion techniques to be once extruded into an integral body, make cable have excellent warp resistance performance and ageing resistace.
