Abstract
A waterproof type division conductor used for power cables comprises an aluminium strand block 1, a waterproof yarn 2, waterproof power 3, an insulation pedion waterproof belt 4, a waterproof rope 5, a semiconductor waterproof binding belt 6, wherein five aluminium strand blocks are twisted into a ring, and the waterproof yarn 2, the waterproof power 3, the insulation pedion waterproof belt 4 and the center filling waterproof rope 5 are added evenly between the layers and the single wire gap inside the aluminium strand block 1 and between each aluminium strand block 1; the semiconductor waterproof binding belt 6 are overlapped on the outside of the aluminium strand block 1 in the ring shape. According to the utility model, copper is replaced by aluminium, thereby saving copper and reducing energy consumption; also effectively preventing the cable conductor from wetting and flooding, effectively restraining water-tree of the cable, increasing reliability and service life of the cable, providing a novel product for the manufacturing field of the power cable.
Description
Technical field: the utility model relates to mechanical manufacturing field, exactly belongs to the electric wire mechanical manufacturing field.
Background technology: at present, in China's electric power system to the application of heavy in section power cable more and more widely, the basic copper milliken conductors that all adopt of heavy in section power cable conductor, the conductor cost accounts for more than 70% of whole cable cost.Along with the develop rapidly that China's electric power network is built, power cable need use a large amount of copper materials, and China's copper resource is seriously deficient, is again precious strategic materials, and bauxite resource enriches relatively.So conductor material for copper, can be alleviated this contradiction with aluminium greatly.In addition, power cable in actual applications since its to lay environment more abominable, cable needs frequent short-term or long period of soaking in water, measure or the measure of blocking water are damaged if cable conductor does not block water, cable can locally be intake, cause the insulation electrical and the mechanical performance of this cable sharply to descend, cause potential safety hazard.
The utility model content: the purpose of this utility model just provides a kind of power cable aluminium milliken conductor that can block water.The utility model is made up of aluminium thigh piece, water blocking yarn, water-proofing powder, insulation single face waterstop, waterproofing rope, the semiconductive strapping that blocks water, with five aluminium thigh pieces strand built in rounded together, evenly interpolation water blocking yarn and water-proofing powder between the layer of each aluminium thigh piece inside and layer, single line slit; Use insulation single face waterstop between each aluminium thigh piece at interval; Simultaneously, waterproofing rope is filled at the rounded center of aluminium thigh piece and aluminium thigh piece strand system; At the rounded overlapping wrapped semiconductives of outer surface of five the aluminium thigh pieces strand system strapping that blocks water.Conductor adopts the annealed aluminium single line, evenly adds water blocking yarn, water-proofing powder, center between the layer of each aluminium thigh piece inside and layer, the single line slit and fills waterproofing rope and the outer wrapped semiconductive strapping adding material water-proof material that blocks water, to reach the purpose that conductor blocks water.On the one hand, the utility model conductor for copper, is saved China's very deficient copper resource at present with aluminium greatly, realizes energy saving purposes.On the other hand, the utility model conductor adopts that novel stop water can effectively prevent to install at cable, lays, the operating into water phenomenon of making moist, effectively suppress the generation of underground cable insulation water tree, significantly improve the reliability and the useful life of mesohigh, extra-high-tension cable, the tremendous economic of avoiding greatly causing because of cable fault is lost, and has the great social and economical meaning to promoting the healthy sustainable development of national economy.
Description of drawings: the utility model specification comprises a width of cloth accompanying drawing, and the drawing of this accompanying drawing is described as follows:
Fig. 1, the utility model structural representation
Among the figure: 1 is aluminium thigh piece, and 2 is water blocking yarn, and 3 is water-proofing powder, and 4 are insulation single face waterstop, and 5 is waterproofing rope, and 6 are the semiconductive strapping that blocks water.
The utility model execution mode: the utility model is made up of aluminium thigh piece 1, water blocking yarn 2, water-proofing powder 3, insulation single face waterstop 4, waterproofing rope 5, the semiconductive strapping 6 that blocks water, by five aluminium thigh pieces 1 strand built in rounded together, evenly interpolation water blocking yarn 2 and water-proofing powder 3 between the layer of aluminium thigh piece 1 inside and layer, single line slit; Use insulation single face waterstop 4 between aluminium thigh piece 1 and the aluminium thigh piece 1 at interval; The center filling waterproofing rope 5 that aluminium thigh piece 1 is rounded with aluminium thigh piece 1 strand system; In the rounded overlapping wrapped semiconductive of outer surface of five aluminium thigh pieces 1 strand system strapping 6 (see figure 1)s that block water.Wherein, aluminium thigh piece 1 adopts annealed aluminium single line strand system to form, and aluminium single line tensile strength is 125N/mm
2, aluminium single line percentage elongation is 8%; Water blocking yarn 2 is to follow the aluminium single line to twist in aluminium thigh piece 1; Water-proofing powder 3 adheres between the aluminium single line in the slit.
