Type designation???phase 3 6 10kV Transformer/ 3 phase transformer/ variable transformer

Structure? ?phase 3 6 10kV Transformer/ 3 phase transformer/ variable transformer

This model variable transformer 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 the iron-core concentrically and cast with epoxy resin, the three phases cast and fixed together, the primary winding and terminal A are 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 installation, type A is installed on the side and the installation hole is on the iron-core clamp, type B has a base for installation.
