Description:
The types of voltage transformers are full en-closed structure of outdoor cast-resin insulation.They have much merit, such as: electric arc resistance, ultraviolet ray and aging resistance,long creepage distance,little partial discharge and large caliber of resistance to over-voltage.They are used for metering electric energy; voltage control and relay protection in the electric system up to rated frequency 50Hz or 60Hz and rated voltage 24kV The transformers can be executed according to the standards IEC61869-1&3.
