500 kVA-33/6.6kV Transformer Manufacturing Process
500 kVA-33/6.6kV Transformer Winding
Winding:
1.Our windings are made of high quality copper.
2.Both High Voltage (HV) and Low Voltage (LV) windings are done using Coil Winding Machines. The Copper strips/wires used in winding are meticulously selected for its quality to give the best output. The Copper strips/wires are paper covered and acts as insulators.
500 kVA-33/6.6kV 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.
