We at SVT we have an extensive product range of Hermetically Sealed type transformers with Corrugated Radiator Panels from range of 25 KVA to 5,000 KVA up to 33 KV voltages. Hermetically sealed oil transformers are normally manufactured with a sealed tank equipped with fins that allow the expansion at the temperature variations. The tightness of the tank is up to 0.5 Bar. This type of transformer is the most widely used in the world.
In the hermetically sealed transformer, the oil does not come into contact with the air and its electrical properties are therefore not compromised, ensuring a long life span of the transformer. The transformer oil is also used for cooling the inside coils to the outside of the transformer. The transformer tank is sealed hermetically to prevent air coming into and contact with the oil inside the transformer. We adhere to IS 2026 and BEE Standards.
Features and Benefits
- The hermetically sealed oil transformers are normally manufactured with a sealed tank equipped with fins that allow the expansion at the temperature variations
- In the hermetically sealed transformer, the oil does not come into contact with the air and its electrical properties are therefore not compromised, ensuring a long life span of the transformer
- The transformer has low maintenance as there is no need for testing the oil or the insulation for a period of 10 years. This reduces the life cycle cost of the Transformer.
