Product Description

Oil-immersed transformers leverage oil as the core insulator and cooling agent. Depending on the cooling technique, they are categorized into oil-immersed self-cooling, oil-immersed air cooling, oil-immersed water cooling, and forced oil circulation. The pivotal components encompass the iron core, winding, fuel tank, oil pillow, breathing apparatus, explosion-proof tube (pressure relief valve), radiator, insulation sleeve, tap changer, gas relay, thermometer, and oil purifier.
