Product Overview

Nacelle top-mounted oil-immersed transformers are specially developed for offshore wind power applications. The unit adopts low-flammability insulating oil and is mounted on the nacelle top of offshore wind turbines with two installation options: suspension mounting and foot mounting. Its low-voltage side connects to 1.5kV low-voltage switchgear to provide wind turbine side protection, stepping up the 1140V alternating current output from the converter to 35~110kV. The high-voltage side is cabled to high-voltage cabinets for grid-side protection, completing power boosting and grid connection for wind turbines.
