SCOPE of application


Because of the need of fire prevention, oil-immersed transformer is usually installed in a single

transformer room or outside, which has the characteristics of large volume, low cost, simple

maintenance, good heat dissipation, strong overload capacity and wide adaptability to the


In operation of oil-immersed transformer, the heat of winding and iron core is first transmitted

to oil, and then to cooling medium through oil. oil-immersed transformer equipment uses oil as

the main insulation means of transformer, oil-immersed transformers are widely used in power

plants, steel plants, railwaysand other large-scale mechanical manufacturing industries.

oil-immersed transformers rely on oil as cooling medium. It is suitable for power system of

petrochemical, electric power, light textile, metallurgy,machinery, building materials, coal, mine,

city construction, civil aviation, port and other industries and enterprises, as rated frequency 50HZ

rated capacity 30 ~ 1600KVA, rated voltage 10KV on high voltageside, low voltage side rated

voltage 0.4 kv power distribution.
