[0002] In the field of wind power generation, aluminum alloy cables for wind power are key components that connect various parts of wind turbine generators and transmit electrical energy to the grid. Their performance directly affects the stability and reliability of the entire wind power system.

[0003] Currently, most existing aluminum alloy cable harnesses adopt a simple stranded conductor and single sheath design in terms of structure. Under frequent torsion conditions, they are prone to breakage, surface wear and cracking, resulting in shortened cable life and increased failure rate, which seriously affects the safe operation and economic benefits of wind power systems.

[0004] Therefore, the problem mentioned above is solved by using torsion-resistant aluminum alloy cable harnesses for wind power. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned shortcomings in the existing technology by proposing a torsion-resistant aluminum alloy cable harness for wind power.

[0014] 1. This utility model, by providing a conductor layer for transmitting electrical energy or signals, maintains conductive continuity and mechanical flexibility during bending and torsion; by providing a shielding layer, which is extruded onto the conductor to form a smooth interface, effectively homogenizing the electric field distribution and eliminating local electric field concentration caused by burrs and gaps on the conductor surface, greatly improving long-term electrical durability and resistance to electrical breakdown; by providing an insulating layer to isolate the conductor layer and prevent short circuits, while the highly elastic material can withstand tension and compression during torsion; and by providing an inner lining layer, which is made of high-wear-resistant polyamide 12, which has excellent mechanical strength, toughness and low coefficient of friction, it provides a strong and smooth platform for the armor layer, allowing the armor wires to slide slightly during torsion without abrading the internal structure, while effectively transferring and dispersing torsional stress to the armor layer.

[0015] 2. This utility model features an armor layer made of high-strength galvanized ultra-high-strength steel wire, providing uniform mechanical protection and high flexibility. During torsion, the braided mesh expands and contracts like a spring, absorbing and releasing torsional stress to protect the internal core wires.
