10kv 100kVA Oil Immersed Transformer Main Characteristics:

1. Designed by patented technology and software with premium performance.
2. Core is made of high quality cold-rolled grain-oriented silicon steel sheet which produced in step-lap technology.
3. Winding is using high strength enameled wire or paper-insulated wire or copper belt, which offers uniform distribution of ampere-turns, reasonable insulation structure with high ability to withstand short-circuit.
4. Oil tank is corrugated type with high corrosion resistance. Tank surface pre-treatment liquid and coating powder adopts international top brands. The tank is degreasing, pickling, phosphorated, electrophoresis by automatic production lines, then power spray coating and heat-solidify.
5. The active part applies core free-hanging structure. The gasket is made of high-quality acrylate rubber which can inhibit ageing caused by sun and heat.
 

10kv 100kVA Oil Immersed Transformer Applications

1. Building Infrastructure and Industrial: Airports, hospitals, factories, shopping malls, hotels, commercial and residential towers.
2. Utility: Generation, transmission, distribution substations, water and waste water treatment plants.
3. Oil and Gas: Oil and gas plants, petrochemical plants and refineries.
