Three Phase 630kVA 33kV Oil Immersed Transformer

Oil type transformer (also called as oil-immersed transformer or oil-filled transformer) is suitable for outdoor. Voltage for customized: 6kV, 10kV, 11kV, 13.2kV, 15kV, 20kV, 33kV, 35kV, etc.

• New structure and reasonable design. Optimize the insulation technology, improve the mechanical strength and anti short circuit ability. The core is made of high quality cold rolled silicon steel, the surface coating paint, with low loss and noise. The appearance is fancy, with easy and reliable operation.
• Adopting the corrugated tank sealing structure to prevent the transformer from the contact with air and water, reducing the degree of aging of the oil and extending the service life of the transformer. 
• The product structure is for the outdoor type, and the transformer has a pressure release safety devices. When a transformer failure pressure is too high, it can safely release reliably through the pressure relief valve to prevent the expansion of the accident.
