Fully sealed structure, transformer body in the oil tank, can be used in the site environment is worse place, such as cement, steel, coal and other industries.

In terms of appearance design, the large and bulky plate radiator is abandoned, and the spiral plate forced oil circulating water cooler with mature structure is used instead. Its volume is small, weight is light, cooling efficiency is high, two sets of oil pumps are standby for each other; its insulation level is high, partial discharge is small, and product life is long; it can be decomposed and recycled after environmental protection life, laying a solid foundation for building circular economy. Due to the problems of volume and heat dissipation, the dry-type rectifier transformer for variable-frequency speed regulation is difficult to make when the capacity is more than 10000 KVA, and this transformer is more suitable for making large capacity transformer. Our company has made 17000 / 6 oil immersed transformer.
