JSZW3-3,6,10 type voltage transformer is semi-closure casting with epoxy resin,which maingly used for measuring voltage or electric energy and protecting relay in power system with frey 50Hz and rated voltage 3kv,or 6KV,or 10Kv and the neural point is not effectively grounded. These products have two different types according to installation method:type A and type B.

This model voltage transformer semi-casting type,with small size and good climate adaptability.T

He 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 terminalA are fully insulated and terminal N is not fully insulated. The wiring please reffers to Diagran 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.
