Description: The Factory Three Phase Copper Oil Type Distribution Electric Transformer 33kv 630kva is a high-quality transformer designed for efficient power distribution. With a power capacity of 630kva and an output voltage of 33kv, this transformer is suitable for various industrial applications. It is built with durable copper materials and features oil-immersed technology for reliable performance. Whether you need a transformer for a high voltage application or for use in an induction furnace, this product is a versatile and cost-effective solution. Trust in the quality and performance of this three-phase transformer for your power supply needs.

Oil-immersed transformer is based on oil as the main insulation means of transformer, and relies on oil as the cooling medium, such as oil-immersed self-cooling, oil-immersed air cooling, oil-immersed water cooling and forced oil circulation. The main components of the transformer are iron core, winding, fuel tank, oil pillow, breathing apparatus, explosion-proof tube (pressure relief valve), radiator, insulation sleeve, tap changer, gas relay, thermometer, oil purifier and so on.
