This 630KVA 10KV Three Phase Oil Immersed Transformer produced by our factory uses very high-quality silicon steel sheets as the material for its core. The transformer windings are made of new materials, and they are combined into the body using new technologies. This significantly reduces the no-load loss and load loss of the transformer. Thus, it becomes more energy-efficient and cost-effective.
This 630KVA 10KV Three Phase Oil Immersed Transformer has eliminated the design of the oil storage tank, reducing the operation and maintenance methods of the transformer.It is also highly suitable for countries and regions with large temperature differences, minimizing the oil leakage risk of oil-immersed transformers. It adopts a corrugated oil tank to replace the traditional oil pipe structure, which not only boosts the heat dissipation efficiency of the 630kVA 10kV oil-immersed transformer but also enhances its operational stability. The exterior of the transformer tank is also treated with a moisture-resistant and anti-corrosion coating process to ensure product integrity during long-distance transportation.
This model is widely used in:
Industrial plants
