The JDZX10-17.5 and JDZX10-24 are 24kV indoor single-phase epoxy resin voltage transformers designed for use in single-phase or three-phase AC circuits. They are used for measuring electric capacity, voltage, and providing protective relaying in systems operating at 50Hz or 60Hz.
These transformers feature a fully enclosed epoxy resin casting with low magnetic density cores and a large creepage distance for superior external insulation. They offer high reliability, are maintenance-free, and comply with IEC 60044-2 and IEC 61869-1 & 3 standards, ensuring safe and stable indoor operation.
