epoxy resin casting
voltage transformer, epoxy resin casting and full-enclosed construction, is widely used for measuring current, electric energy and relay protection in the single phase or three phase power system with the frequency of 50Hz or 60Hz and rated voltage of 10kV or 11 kV.
The core adopts advanced cold-rolled silicon steel sheet. Primary winding high voltage outgoing terminals lead out by high tension fuse, secondary winding outgoing terminals from transverse side of the product. The product has the feature of high reliability and free of maintenance etc.
