20kV Cast Resin Dry-Type Power Transformer iec 60076

 

The 20kV Cast Resin Dry-Type Power Transformer is a high-performance high-voltage power distribution equipment, designed for medium and high-voltage power grid transmission and distribution scenarios. Adopting advanced epoxy resin vacuum casting technology, the winding is integrally cast, which effectively improves the insulation strength, moisture resistance, dust resistance and corrosion resistance, ensuring stable operation in harsh environments.

 

 

Rated at 20kV voltage level, the transformer adopts a reasonable structural design, with optional F/H insulation class and AN/AF air cooling mode. It features no insulating oil, zero risks of oil leakage, fire and environmental pollution, and has the advantages of low noise, compact structure, small floor space and easy maintenance, which can greatly reduce the difficulty and cost of installation and operation.
