500kva Distribution Step up Transformer 120v to 240v

Main feacture

• 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
