The JDZ10-12R is a 12kV indoor single-phase voltage transformer featuring epoxy resin casting and a fully enclosed structure. It is widely applied in single-phase or three-phase AC power systems for voltage measurement, electric energy metering, and protective relaying at rated frequencies of 50Hz or 60Hz, with a highest equipment voltage of 12kV.
This transformer utilizes an advanced cold-rolled silicon steel sheet core to ensure low magnetism and high accuracy. The high-voltage primary winding lead is routed from the top, while the secondary winding lead exits from the transverse side, enabling efficient wiring. With features such as high reliability and maintenance-free performance, it complies with IEC 60044-2 and IEC 61869-1 & 3 standards.
