Abstract

A cable used for a wind generator. The core of the cable comprises a conductive core. A design method of concentrically cladding a copper layer on an aluminum core, with the copper-aluminum interface closely fused together is used to form the conductive core. The outside of the conductive core is clad with an insulating layer; the outside of the insulating layer is clad with a wrapping tape layer, and a fluorine plastic sheath is arranged outside the wrapping tape layer. The cable used for a wind generator has the benefit effects of reducing production cost, saving resources, and simultaneously helping to curb the price of copper, by using a copper clad aluminum core to substitute a pure copper core in the conductive core.

Description

A kind of cable for wind-driven generator

?

Technical fieldThe present invention relates to a kind of cable for wind-driven generator, belong to field of cables.

Background technologyThe industries such as generation current factory, transformer station, smelting and petrochemical industry, very big to the demand of control cables, especially for the Special high-temperature anti-corrosion cable of the environment occasion such as anticorrosion, high temperature resistant.Wires and cables industry has been developed the high temperature resistance control cable of fluoroplastic insulation fluoroplastic sheath and the high temperature resistance control cable of silicon rubber insulation silicone rubber jacket in succession, has satisfied preferably above industry to the demand of high temperature resistance control cable; Because the fast development of World Economics and China's economic, supply falls short of demand in global copper market, and China uses copper big country in addition, and is powerful to the Requirement of copper, and the internal copper demand is very outstanding greater than the contradiction of supplying with, and causes the copper price increase.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 large.

Summary of the inventionIn view of the defective that prior art exists, it is few to the purpose of this invention is to provide a kind of copper consumption, the cable for wind-power generator that cost is low.

For achieving the above object, the technology used in the present invention solution is: a kind of cable for wind-driven generator, its internal layer comprises conductive cores, described conductive cores adopts on the aluminium core the with one heart design of coated copper layer, 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.

Described insulating barrier adopts perfluoroethylene-propylene to make.

A kind of cable for wind-driven generator, its beneficial effect is: conductive cores replaces the fine copper core with copper-covered aluminum-core, reduces production costs, and economizes on resources, and is conducive to simultaneously suppress the copper valency.
