Abstract

The invention discloses an aluminum alloy torsion cable for wind power generation and a crimping method, the aluminum alloy torsion cable comprises an aluminum alloy torsion cable and a connecting terminal, and the aluminum alloy torsion cable comprises a main wire core conductor, a reinforced non-woven fabric layer, a waterproof adhesive layer, an insulating layer, a metal wire braided shielding layer, an inner protection layer and an outer protection layer which are sequentially arranged from inside to outside; and the connecting terminal comprises a copper-aluminum terminal, an aluminum alloy bolt and a gasket. .The cable is provided with the terminal, is convenient to install, is high in cost performance, is directly fastened through the aluminum alloy bolt during connection, is buffered through the gasket, increases the compactness, improves the tensile strength, is simple and reasonable in overall structure, can completely or partially replace a conventional copper torsion cable, reduces the weight of the cable, and improves the electrical performance and torsion resistance of the cable The tensile and load bearing characteristics of the aluminum conductor are also improved, and terminal crimping is facilitated; the cable has good waterproof performance and shielding performance; and the processing technology is simple and feasible, and the wire harness crimping of the aluminum alloy torsion cable can be rapidly realized.

Description

technical field [0001] The invention belongs to the technical field of wind power cables, in particular to an aluminum alloy torsion cable for wind power generation and a crimping method. Background technique [0002] With the introduction of the national carbon emission policy, clean energy such as wind power has developed rapidly. The introduction of wind power subsidies in 2020 will put a greater test on the cost of wind power generation. How to reduce the cost of cables without reducing the reliability of wind turbine power transmission is a problem that wind power mainframe manufacturers and cable companies need to face together. Our country has always been rich in aluminum and low in copper. Substituting aluminum for copper can not only greatly reduce costs, but also reduce the impact of fluctuations in foreign markets, thereby driving the domestic market. [0003] Wind power torsion cables require frequent rotation of the random cabin, and the cables must bear the t...
