Hitachi Energy liquid-filled, pressure-compensated subsea transformers are rated for depths up to 3,000 meters.
They reduce the high-voltage to levels that can be used by pumps, motors, and compressors while providing reliable performance and cost benefits.
Deep sea equipment sets a high benchmark in terms of technology and solutions. Hitachi Energy started developing the technology in the mid-1980s and introduced the first subsea transformer in 1999. Hitachi Energy subsea transformers are engineered to provide superior performance and cost benefits for subsea rotating equipment far from a power supply. Over the last decade, we have supplied around twenty subsea transformers.
Hitachi Energy remains the world’s leading manufacturer of subsea transformers capable of delivering reliable power underwater with minimal losses.
Subsea Transformers product scope:
- Voltage: up to 145 kV AC
- Current: up to 900 A
- Water depth: up to 3000 meters
