The JDZ-36 is a 36kV indoor single-phase voltage transformer featuring epoxy resin casting and double-pole insulation. It is widely used in isolated neutral systems for measuring voltage, electric energy, and protective relaying, operating at frequencies of 50Hz or 60Hz, with an insulation voltage rating of 36kV (up to 40.5kV).
This transformer incorporates an advanced cold-rolled silicon steel sheet iron core to ensure high accuracy and low losses. The high-voltage primary winding lead is routed from the top of the transformer, while the secondary winding lead exits from the transverse side. It meets international standards IEC 60044-2 and IEC 61869-1 & 3, and supports a load power factor of cosΦ=0.8 (lagging), ensuring reliable and efficient indoor operation.
