Accumulators and TGA

Accumulators and through gearbox assemblies (TGA)

Accumulators
As the backup for the hydraulic system, accumulators play a vital role. The wind turbine industry tends to use either bladder or piston accumulators, and because there are advantages to using one type over the other in certain situations, we use our experience – and rigorous testing – to select the ideal accumulator for your wind turbine. The hydraulic accumulators acts also as the failsafe energy reserve to ensure that the pitch system is always capable of stopping the turbine hence this is a key component.

Through gearbox assembly (TGA)
Our through gearbox assemblies keep all the components in the hub running smoothly. From the power pack installed in the nacelle oil is pumped to the actuators that move the blades.

Of course, we can also tailor the through gearbox assembly to meet your particular needs – and if required, our designs can include assistance for the rotating union or the choice of slipring.
