The proposal of “carbon peak” and “carbon neutral” goals has accelerated the development of new wind and solar energy. In 2021, onshore wind power subsidies will be refunded, which will also intensify the demand for cost reduction of wind power, resulting in a rapid increase in the application of aluminum alloy cables. In addition, the introduction of new foreign technologies has promoted the rapid advancement of domestic wind power cost reduction programs.
The application of aluminum alloy cables in wind power has mature domestic cases, mainly in the fixed laying section of the tower. The introduction of new foreign technologies has further expanded the application of aluminum cables. The use of 8030 aluminum alloy conductors and the design of category 5 conductors make it possible to apply aluminum alloy cables in the torsion section.
By benchmarking the performance of foreign aaac conductors, the aluminum conductor adopts the same stranding process as the copper cable. Because the aluminum wire is lighter, the advantage of the aluminum cable is more obvious from the point of view of flexibility.
Reducing this cost saving is the eternal theme of the sustainable development of enterprises. The weight of the aluminum alloy conductor is reduced, and the load-bearing requirements of the sheath are simultaneously reduced, and the thickness of the sheath is also reduced in response, so the loss is smaller. Using aluminum alloy torsion cable design, the cable can be designed as a whole laying plan, which reduces the design of intermediate joints and can further reduce risks and costs.
Wind power has always been the main force in the development of new energy. How to ensure the long-term fast and efficient operation of wind turbines is the direction that wind power mainframe companies have been pursuing. Development of aluminum alloy cables has reduced the cost of wind turbine cables, reduced the risk of cable decline due to its own weight, and promoted the rational application of my country’s aluminum resources.
