This model voltage transformer is semi-casting type, with small size and good climate adaptability. The iron-core of the

transformer applies core type side-iron structure, and made of high-quality silicon steel plate by cold rolling and exposing in the air, the primary winding, secondary winding and residual voltage winding wound onto theiron-core concentrically and cast with epoxy resin, the three phases cast and fixed together, the primary winding and terminal A is fully insulated and terminal N is not  fully insulated. The wiring please refers to Diagram 1.

It has two types: type A and type B according to insulation, type A is installed on the side and the insulation hole is on theiron- core clamp, type B has a base for installation.
