The JSZV8-12R is a 12kV indoor three-phase voltage transformer with epoxy resin casting and fully enclosed construction. Equipped with built-in fuses, it is designed for measuring voltage, electric energy, and protective relaying in electrical systems operating at 50Hz or 60Hz, with a maximum equipment voltage rating of 12kV.
This transformer offers high reliability, a low magnetism core for improved accuracy, and a large creepage distance to ensure excellent external insulation. It is maintenance-free and complies with international standards IEC 60044-2 and IEC 61869-1 & 3, making it suitable for stable and safe operation in indoor power systems.
