Introduction of the structure
This series transformer is epoxy resin casting type insulation structure, the core of fold type, core column on the suit the primary and secondary windings, the primary winding and secondary winding are concentric, around the same skeleton, the whole coil, external use epoxy resin casting forming secondary winding wire through two built-in nut on the casting body for a.x derivation. A winding lead by the two high pressure on the casting body terminal WeiOu derivation A.X
