Step-up transformers convert generated electricity to the听requisite voltage level for power transmission on high-voltage听lines and cables. A step-up transformer in a nacelle听of a wind turbine converts the generated wind electricity to听the kV-level needed, to serve the switchgear at the bottom听of the wind tower.

德州扑克在线 offers two kinds of step-up transformers for听wind application: Fire resistant GEAFOL cast-resin transformers听for up to 40.5 kV and FITformer REN transformers听up to 66 kV, with ester, a flame-retardant, biodegradable insulating fluid.
听
For on- and offshore windparks we delivered about听30.000 units of GEAFOL transformers and 1.000 units out听of it where delivered for offshore wind projects. More听than 2.500 units of the ester fluid immersed FITformer听REN where installed in wind offshore applications worldwide.

The latest development is the FITformer REN model that听enables power transmission at the 66 kV level for even more听efficiency and highest proven reliability. The extremely听compact transformers fit directly into the nacelle.听To enable the transformers to withstand the strong听vibrations in the nacelle, 德州扑克在线 developed a听mechanically reinforced version specifically for wind听turbines. The first practical application for the FITformer听REN was the 28 MW offshore wind farm Nissum Bredning听Vind located in the waters of North-western Denmark.
