The JDZ10-12QB 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.
This transformer offers high reliability with a low magnetism core and features a large creepage distance on the external insulation, enhancing its resistance to pollution. It is maintenance-free and supports a load power factor of cosΦ=0.8 (lagging). The product complies with IEC 60044-2 and IEC 61869-1 & 3 technical standards, suitable for equipment rated up to 12kV.
