S9 series three phase oil immersed power transformer (range from 30KVA to 2000KVA) are suitable for 10KV, 50HZ distribution system. It can be widely used in residence, street, factory, countryside lighting and power use.
Compared to general oil-immerse transformer, Full sealing power transformer canceltheoilconservator. Use bellows instead the oil pipe or as cooling radiator. The coil core assemble and oil is fully isolatedrom the atmosphere, the bellow may flexible expand or shrink along with the transformer oil volume change influenced by temperature. The oil preservation system ffectivelypreventsairandmoisturepermeate, retard aging rate of oilpaper insulation to prolong service life of transformer. So it is aintenance free. Full sealing power transformer has pressure relief valve.
