The JDZX10-12 is a 12kV indoor single-phase voltage transformer designed for use in single-phase or three-phase AC circuits. It is used to measure voltage, electric capacity, and provide protective relaying in systems operating at 50Hz or 60Hz, with a highest equipment voltage of 12kV.
The transformer features a fully enclosed epoxy resin casting structure with low magnetic density and a large creepage distance for external insulation. These features ensure high reliability and pollution resistance. The product is maintenance-free and complies with IEC 60044-2 technical standards, supporting a load power factor of cosΦ=0.8 (lagging).
