The JDZ10-12QC is a 12kV indoor single-phase epoxy resin voltage transformer featuring epoxy resin casting and double-pole insulated fully enclosed construction. It is designed for indoor use to measure voltage, electric energy, and provide protective relaying in electrical systems operating at 50Hz or 60Hz, suitable for equipment rated at 7.2kV or 12kV.
This transformer is characterized by high reliability, a low magnetism core, and a large creepage distance on its external insulation, enhancing resistance to pollution. Maintenance-free in operation, it supports a load power factor of cosΦ=0.8 (lagging) and complies with IEC 60044-2 and IEC 61869-1 & 3 standards.
