The JDZ10-12C 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 applications to measure voltage, electric energy, and provide protective relaying in electrical systems operating at 50Hz or 60Hz, with equipment voltage ratings up to 12kV.
This product offers high reliability with a low magnetism core, ensuring accurate measurement and stable operation. Its external insulation has a large creepage distance to resist pollution, and the transformer is maintenance-free. It supports a load power factor of cosΦ=0.8 (lagging) and complies with IEC 60044-2 and IEC 61869-1 & 3 standards.
