Product Details

Rated capacity: 10-2500kVA

Voltage combination:

High: 38.5KV 35KV

Low: 0.4kV

Low loss and noisy

Compared with normal oil immersed power transformer has no oil storage box and adopts the corrugations on the oil tank as its heat-radiation parts

Oil tank is made by fine cold-rolled steel on an exclusive production-line

Corrugations can expand or contract according to the change of oil volume

Thus the inner space of transformer can be isolated from the air

which can reduce the aging speed of oil and prevent the insulation materials from damping

Oil-immersed transformer possesses a reliable operation and is free from maintenance
