Product Overviews
Resin-insulated dry-type transformers feature high safety, flame retardancy and zero pollution, and can be installed directly at load centers. They are maintenance-free and easy to install, with low overall operating cost and power loss. Thanks to excellent moisture resistance, the transformers operate reliably at 100% relative humidity, and can be restarted without pre-drying after shutdown.With low partial discharge, low noise and outstanding heat dissipation, they can run at 150% rated load under forced air cooling. A complete temperature protection & control system is equipped to ensure secure operation, delivering high operational reliability.
