Hitachi Energy delivers 1st 66 kV transformer with ester for offshore wind

Hitachi Energy has achieved a major milestone by delivering the first 66 kV transformer with natural ester insulation, designed specifically for offshore wind applications. This groundbreaking transformer, which uses biodegradable and environmentally friendly natural ester instead of traditional mineral oil, represents a significant advancement in sustainable energy solutions for the offshore wind industry.

The 66 kV transformer is a critical component for efficient power transmission from offshore wind farms to the mainland. By using natural ester, which is non-toxic and renewable, the transformer enhances safety and reduces the environmental impact of wind energy operations. This innovative solution also helps wind farm operators meet stringent environmental regulations while improving performance and reducing fire risks.

Hitachi Energy’s latest innovation demonstrates its ongoing commitment to supporting the global energy transition toward more sustainable and renewable power sources. As the demand for clean energy grows, this transformer plays a crucial role in enabling the expansion of offshore wind projects around the world.
