Transformers for solar and wind plants

Renewable energy

Transformers for solar and wind plants

Step-up transformers for solar and wind plants and energy storage systems: they raise inverter output voltage to 6, 10 or 35 kV. Designed for variable and intermittent generation. The dry-type design with non-combustible epoxy insulation eliminates the risk of oil leaks and fire.
