JSZW 2A-12R MV Voltage Transformer 12kV Three-Phase Voltage Transformer High Reliability
1.Product Introduction:
Voltage transformer with fully enclosed cast insulation structure, the primary and secondary windings and toroidal core all encapsulated in epoxy casting body, using elbow-type plug to increase the outer insulation creepage distance and resistance contamination and moisture performance. It is used indoor for measuring voltage, electric energy and protective relaying in three-phase AC circuit with the frequency 50Hz or 60Hz and highest voltage for equipment 12M
The primary cone accords with IEEE 386-2006 figure 7.
