The JDZX9-12G is a 12kV indoor single-phase voltage transformer designed for use in single-phase or three-phase AC circuits. It is used to measure electric capacity, voltage, and provide protective relaying in systems with rated frequencies of 50Hz or 60Hz, for equipment operating up to 12kV.
Constructed with a fully enclosed epoxy resin casting design, this transformer features low core magnetism density and a large creepage distance, enhancing insulation and resistance to pollution. It delivers high reliability and requires no maintenance. The product conforms to IEC 60044-2 and IEC 61869-1 & 3 technical standards, supporting a load power factor of cosΦ=0.8 (lagging).
