Abstract
The utility model relates to a cable for a wind-power generator, and the inner layer of the cable comprises a conducting core, wherein the designing mode of concentrically coating a copper layer on an aluminum core is adopted by the conducting core, copper and aluminum interfaces are closely fused together, an insulating layer is coated outside the conducting core, a belting layer is coated outside the insulating layer, and a fluoroplastic jacket is arranged outside the belting layer. The cable for the wind-power generator has the beneficial effects that: a copper-coated aluminum core is used as the conducting core for replacing a pure copper core, so that the production cost is lowered, resources are saved, and meanwhile, the cable for the wind-power generator is favorable to inhibiting the price of copper.
Description
Technical fieldThe utility model relates to a kind of wind-driven generator cable, belongs to field of cables.
Background technologyIndustries such as generation current factory, transformer station, smelting and petrochemical industry, very big to the demand of control cable, especially for the extraordinary high-temperature anticorrosion cable of environment occasion such as anticorrosion, high temperature resistant.Wires and cables industry has been developed the high temperature resistant control cable of fluoroplastic insulation fluoroplastics sheaths and the high temperature resistant control cable of silicon rubber insulation silicone rubber jacket in succession, has satisfied the demand of above industry to high temperature resistant control cable preferably; Because World Economics and fast development of Chinese economy, supply falls short of demand in global copper market, and China uses copper big country in addition, and is powerful to the demand situation of copper, and the internal copper demand is very outstanding greater than the contradiction of supplying with, and causes the copper price to rise.Because it is higher that copper material accounts for the production cost of such cable, therefore cause the material cost of this cable significantly to increase, the operated pressure of enterprise is big.
Summary of the inventionIn view of the defective that prior art exists, it is few that the purpose of the utility model provides a kind of copper consumption, the wind-driven generator cable that cost is low.
For realizing above-mentioned purpose; The technical solution that the utility model adopted is: a kind of wind-driven generator cable, and its internal layer comprises conductive cores, said conductive cores is employed in the design that coats the copper layer on the aluminium core with one heart; And copper aluminium interface is closely merged; Be coated with insulating barrier in conductive cores, insulating barrier is outer to be coated by belting layer, and belting layer is outward the fluoroplastics sheath.
Said insulating barrier adopts perfluoroethylene-propylene to process.
A kind of wind-driven generator cable, its beneficial effect is: conductive cores replaces the fine copper core with copper-covered aluminum-core, reduces production costs, and economizes on resources, and helps suppressing the copper valency simultaneously.
