Product Description
This series of products are more advanced in design and have been greatly improved in material , stucture and technology . High and low pressure clamps are made of steel strip or upper beam and side beam , forming a strong frame structure to enhance the damping force of iron core and its resistance to transportation impact.Strong short drcuit resistance , beautiful appearance , reliable operation , low loss , low noise , reach the advanced level of similar products abroad .
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.
