Main Gearboxes
NGC manufactures both serial-produced and fully-custom gearboxes for multi-megawatt wind applications installed onshore and offshore.
Each gearbox design is precisely calculated based on real-world operating conditions and installed load spectrums to ensure optimized torque density, capacity, efficiency, and reliability.
In addition, performance tests, including an accelerated life test (HALT) and low-temperature test (CCV), are performed to further simulate the actual operating conditions.
Proven product reliability and our commitment to customer satisfaction are why NGC’s gearbox solutions are qualified by leading turbine manufacturers domestically and abroad.

Pitch & Yaw Drives
NGC is a globally-leading supplier of multi-megawatt pitch and yaw drives. As with our main gearboxes, our pitch and yaw drives are designed to withstand demanding, real-world operating conditions, including low temperatures, variable wind speeds, and high-altitude installations.
Our manufacturing, assembly, and testing processes are strictly controlled to ensure that our products exceed all expectations.
