Abstract
The utility model relates to a kind of shielding high-voltage shield cable, comprise cable core and insulating sleeve, it is characterized in that in sheath, there is three-phase electricity cable core, every phase cable core has insulating sleeve I in one deck outward, outer one deck conductive rubber I that is with of interior insulating sleeve I, this conductive rubber layer I has one deck to be wound around metallic conduction silk outward, and the periphery that the cable core of three facies tract sheath I adds after turning round also has insulating sleeve II, conductive rubber layer II, conductive wire, outer insulation jacket in one deck successively.
Description
Technical field
The utility model relates to cable, is specially a kind of shielding high-voltage shield cable.
Background technology
Now from low pressure to high-voltage transmission, have greatly the trend that replaces aerial exposed electric wire from underground jacketed cable, high-voltage transmission cable application is more and more wider.In the use procedure of high-voltage transmission jacketed cable, often in sheath between phase line, between cable and external environment occur that local electrophoresis blows out phenomenon (an ablation cable cover(ing) is put in part), in order to overcome this phenomenon, be usually filling conductive plastic establish a parallel ground connection zero line and contact with conductive plastic between cable jacket and inner sheath, blow out to shield electrophoresis.But the problem that this design exists is: ground connection zero line is not distributed between interior oversheath equably, still there iing electric capacity to blow out phenomenon away from the opposite side of conduction zero line.
Summary of the invention
The purpose of this utility model is: overcome the defect that still has electrophoresis to blow out in prior art, a kind of improved shielding high-voltage shield cable is provided.
The technical solution of the utility model is: a kind of shielding high-voltage shield cable, comprise cable core and insulating sleeve, in sheath, there is three-phase electricity cable core, every phase cable core has insulating sleeve I in one deck outward, outer one deck conductive plastic I that is with of interior insulating sleeve I, this conductive plastic layer I has one deck to be wound around conductive wire outward, and the periphery that the cable core of three facies tract sheath I adds after turning round also has insulating sleeve II, conductive plastic layer II, conductive wire, outer insulation jacket in one deck successively.
Particularly,, there is filler plastic cement adding turn round between gap between described threephase cable in-core insulating sleeve I, and filler plastic cement performance is general, and cost is lower.
Between described three-phase electricity cable core and interior insulating sleeve, be also provided with one deck and be wound around plastic band, its effect is in the time constructing or reclaim waste and old cable, easily makes cable core peel off out from sheath.
The design is by improving the distribution of conductive wire in sheath, when use, conductive wire in sheath is drawn out to earth connection and connects, can more effectively shield between three-phase electricity and cable external environment between spark, and then the electrophoresis that effectively solves high-tension cable is blown out problem.
Brief description of the drawings
Fig. 1 is the utility model shielding high-voltage shield cable section structure schematic diagram.
In figure, 1. outer insulation jacket, 2. conductive wire, 3. conductive plastic II, 4. interior insulating sleeve II, 5. packed layer, 6. conductive wire, 7. conductive plastic I, 8. interior insulating sleeve I, 9. adhesive tape, 10. cable core.
Embodiment
A kind of shielding high-voltage shield cable, comprise cable core and insulating sleeve, in sheath, there is three-phase electricity cable core 10, outside every phase cable core 10, there is insulating sleeve I8 in one deck, outer one deck conductive plastic I7 that is with of interior insulating sleeve I8, the periphery that the cable core that this conductive plastic layer I7 has one deck to be wound around conductive wire 6, three facies tract sheath I outward adds after turning round also has insulating sleeve II4, conductive plastic layer II3, conductive wire 6, outer insulation jacket 1 in one deck successively., can there be filler plastic cement adding turn round between gap between described threephase cable in-core insulating sleeve I, and filler plastic cement performance is general, and cost is lower; Between described three-phase electricity cable core and interior insulating sleeve, be also provided with one deck and be wound around plastic band, its effect is in the time constructing or reclaim waste and old cable, easily makes cable core peel off out from sheath.
