fully sealed oil-immersed power transformer

The oil tank adopts a fully sealed structure. Compared with ordinary oil-immersed transformers, the fully sealed distribution transformer eliminates the oil conservator. The corrugated fins of the oil tank replace oil pipes as cooling and heat dissipation elements. The corrugated oil tank is manufactured from high-quality cold-rolled thin plates on a dedicated production line. The fins expand and contract with the volume of transformer oil, thereby isolating the transformer from the atmosphere, preventing and slowing down oil deterioration and insulation moisture absorption, enhancing operational reliability, and requiring no maintenance under normal operation.

The product features high efficiency and low loss, saving significant amounts of electricity and operating costs, resulting in substantial social benefits. It is a new technology product that should be promoted.

The transformer body adopts a new insulation structure, improving its short-circuit withstand capability; the core is made of high-quality cold-rolled silicon steel sheets; the high-voltage windings are all made of high-quality oxygen-free copper wire and employ a multi-layer cylindrical structure; all fasteners are treated with special anti-loosening measures.
