Tranect manufactures copper electrical connectors and power distribution components for onshore and offshore wind turbine applications. Our products are used wherever high current, low resistance electrical connections are required whilst accommodating vibration, thermal expansion and mechanical movement.
From turbine generators and converters through to transformers, switchgear and substation connections, we design and manufacture custom copper components that provide reliable long-term performance in demanding operating environments.
Whether you require a one-off prototype or production quantities, every component is manufactured in the UK to your drawings or designed in collaboration with your engineering team.
Electrical Challenges in Wind Turbines
Wind turbines present a unique combination of electrical and mechanical demands.
Electrical connections must withstand:
- Continuous vibration from rotating machinery.
- Thermal expansion caused by varying electrical loads.
- High fault currents.
- Outdoor environments with significant temperature variation.
- Corrosive coastal and offshore atmospheres.
- Long service intervals where reliability is critical.
Rigid electrical connections can introduce unwanted mechanical stresses into equipment. Flexible copper connectors allow movement while maintaining a low resistance electrical path, reducing stress on switchgear, transformers and power electronics.
Flexible Laminated Copper Connectors
Tranect designs and manufactures flexible laminated copper busbars for high current applications.
Our laminated connectors consist of multiple thin copper foils diffusion welded or resistance welded into solid contact palms, providing excellent electrical conductivity whilst remaining highly flexible.
Typical applications include:
- Generator connections
- Converter and inverter connections
- Transformer terminals
- LV and MV switchgear
- Power converter cabinets
- Battery energy storage interfaces
- Grid connection equipment
Copper Busbars
Tranect manufactures custom copper busbars for low and medium voltage power distribution systems used throughout wind energy installations.
Busbars can be supplied:
- Plain copper
- Tin plated
- Silver plated
- Formed and bent
- Drilled and machined
- Fully assembled where required
Using CNC machining and precision fabrication, we manufacture busbars to customer drawings or develop complete designs from electrical and mechanical requirements.
Earthing and Lightning Protection
Effective earthing is essential for wind turbine safety and equipment protection.
Tranect manufactures flexible copper braids and earth straps used for:
- Turbine tower earthing
- Nacelle bonding
- Door bonding
- Lightning protection systems
- Transformer earth connections
- Switchgear bonding
- Cable tray bonding
Copper braid provides a highly flexible, low resistance earth connection capable of withstanding continual vibration without fatigue failure.
Our goal is to offer broad capabilities, competitive pricing, exceptional quality and outstanding service to each and every customer.
