Oil-immersed Transformer has the ability to withstand thermal shock, overload capacity, high flame retardant, fire resistance, low loss, low partial discharge capacity, and low noise, are free of hazardous gases, and is environmentally friendly. Insensitive to humidity, small, no cracking, easy to maintain.

Therefore most suitable fire protection requirements high load fluctuation and dirty wet harsh environments. Such as airports, power plants, metallurgical operations, hospitals, high-rise buildings, shopping centers, densely populated areas as well as petrochemical, nuclear power plants, nuclear submarines and other special environment.
