25kVA-0.4/0.69kV Transformer Oil Tank

Oil Tank:

1. The oil tank is a transformer housing containing the iron core, winding and transformer oil.

2. The corrugated tank structure is fully sealed, and the corrugated will expand and compress with the increase of oil, isolating the transformer from the atmosphere and preventing oil deterioration and moisture. After oil removal, rust removal and phosphating treatment, the surface of corrugated oil tank is coated with rainproof paint. Moisture and salt spray.
