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...
