The JDZ9-12Q is a 12kV indoor single-phase epoxy resin voltage transformer featuring epoxy resin casting and double-pole insulation. It is designed for installation inside switchgear cabinets to measure voltage, electric energy, and provide protective relaying in single-phase or three-phase AC circuits with rated frequencies of 50Hz or 60Hz.
This transformer offers high reliability and a low magnetism core, ensuring accurate voltage measurement and stable operation. Maintenance-free by design, it supports a load power factor of cosΦ=0.8 (lagging) and complies with IEC 60044-2 and IEC 61869-1 & 3 technical standards. It is suitable for equipment with voltage ratings up to 12kV in indoor environments.
