35kV 해상 풍력 터빈용 건식 변압기

SCSB-F-7400/35
This product is the first batch of self-developed dry-type transformers for offshore wind turbine towers that have achieved grid-connected operation. It predominantly employs air-water cooling for heat dissipation. The transformer indirectly exchanges heat with the external air through a cooling system. Its function is to step up the 690V or 1140V electrical energy generated by the wind turbine and convert it to 35kV, which is then transmitted to the wind farm step-up station via submarine cables.

Product Advantages
The shell has a high level of protection and efficient heat dissipation.
Strong resistance to corrosion and vibration.
The structure is compact, meeting the requirements for space utilization.
F1-level flame retardant performance, meeting climate C4 and environmental E4 standards.
Special cooling method, optimizing dedicated cooling air ducts.
Application scenario
This product is primarily utilized in offshore wind power projects and is capable of withstanding the harsh climatic and environmental conditions at sea.
