Copper Busbar For Wind Power

Ultra-high conductivity, low loss and high efficiency:
Utilizing 99.99% high-purity electrolytic copper / TU2 oxygen-free copper, with a conductivity of ≥ 98% IACS and a resistance as low as 0.0172μΩ・m, it reduces line loss by 15%-20% and enhances power generation efficiency. The rated current-carrying capacity of the hard copper busbar is up to 6300A, while the flexible copper busbar is suitable for 6000A large current transmission.

Resistant to vibration and weathering, suitable for wind power conditions:
The hard copper bars have a tensile strength of ≥ 280 MPa, and can operate stably within the temperature range of -40℃ to 150℃; The flexible laminated structure can absorb vibrations of 10-50Hz and an acceleration of 15g in the nacelle, counteracting thermal expansion and contraction stress, and preventing bolt loosening and deterioration of the contact surface.

Corrosion-resistant and durable, with long-term maintenance-free:
Surface treated with tin plating / silver plating / spray coating, resistant to salt spray for ≥ 2000 hours, wind and sand abrasion up to 10,000 cycles, IP65 protection, suitable for harsh environments such as high humidity at sea and sand dust on land.

Customized adaptation, easy installation:
Supports customization of cross-section (such as 40mm×8mm, 125mm×5mm, etc.), length, punching, insulation coating, etc.; The contact pressure of the crimping terminal is ≥ 500N, and the installation efficiency is increased by 40%.

Onshore wind power: IGBT module connection of converter, wiring inside the nacelle, grid connection cabinet bus system

Offshore wind power: Conductive connection of generator stator/rotor, DC bus of offshore converter, anti-corrosion grid connection equipment

Other adaptations: Wind power energy storage supporting cabinet, grid connection station bus bar

Q: Why is silver-coated copper busbars preferred for offshore wind power?
A: The silver coating offers better oxidation resistance and lower contact resistance, making it suitable for high-salt spray environments and extending the service life by 30%.

Q: How to select between flexible copper busbars and hard copper busbars?
A: For dynamic connections (such as between the generator and the converter), choose flexible copper busbars to absorb vibrations; for static current collection (such as the busbars of the grid connection cabinet), choose hard copper busbars to ensure current carrying capacity and rigidity.
