Indoor Single-Phase Single-Phase Metallic Coating Touch Proof Type MV Voltage Transformer
1. Introduction:
Voltage transformer is fully enclosed cast insulation structure, the primary and secondary winding, the toroidal core are all encapsulated in the epoxy resin casting body to improve the filterability and moisture resistance. The product plug part is designed to conform to the 2 # inner cone (EN 50181). The overall structure is designed to be fully shielded surface. It is used indoor for measuring voltage, electric energy and protective relaying in single-phase or three-phase AC circuit with the frequency 50Hz or 60Hz and highest voltage for equipment 36kV.
