Product structure
The product is made up of transformer room, H. V room and L. V room.
The performance of the transformer meet the type of SM9 or S11M.
The H. V side adopts type V or T load switch and two poles fuse to protect and use current-limiting fuse to protect circuit, the breaking capacity is big. Plug-in type fuse is used to protect the secondary side overload and short circuit of transformer.
Both load switch and fuse are installed in transformer room and make use of transformer insulation liquid as insulation medium and heat-eliminating medium.
The ingoing on H. V side adopts H. V cable plug and total insulated in the H. V room.

The outgoing on L. V side for that normal product adopts directly outgoing. It can be added L. V measuring and shunt outgoing if customer requires.
The structure of box-body is total-sealed and adopts steel plate welding, beading three sides heat-eliminating. It features of strong antiseptic ability and beautiful appearance after treated by special technology.
The H. V room is isolated from L. V room and has the following components: Load switch, tap changer of transformer, H. V ingoing pin and plug-in type fuse.
The box-body equips has: Oil level thermometer, oil level gauge, pressure release valve, oil drain valve and oil sample valve. L. V outgoing terminals and L. V measuring system which is required to equip by users.
