Transformator

J---Voltage Transformer D---Single-phase Z---Pouring insulation X---With the remaining winding 11---Design numbez F---Measurement and monitoring of separate --20 ---Voltage kV G---Improved Design Third, the structure profile This series of voltage transformer is epoxy resin insulated fully enclosed structure, resistance to contamination and moisture, also applies to the tropical regions. The transformer size, light weight, small amount of partial discharge, anti-voltage capability, suitable for any position, any orientation.

Pay attention to: 1, secondary winding must not use short-circuit and overload operation. 2, JDZX11-20, JDZXF11-20 for the semi-insulating structure, can only sense pressure test; switch cabinet for frequency tests, transformer and switchgear should be disconnected.
