Description
Standard HV voltages are 15.75 kV, 20 kV, 21 kV and 22 kV. The LV winding is built for 800/462, 690/398, 420/242 or 400/231 V to match the inverter output. Cooling is AN or AN/AF with fans. Cast insulation works without a liquid dielectric, so the transformer needs no oil monitoring. Standards are IEC 60076-11 and EN 50708.
