The JDZX18-24R Voltage Transformer is designed with a full epoxy resin casting and fully enclosed construction, ideal for indoor installation in switch cabinets. It is used for measuring current, electric energy, and for protective relaying in single-phase or three-phase AC circuits. Operating at 50Hz or 60Hz, the transformer supports systems with a highest voltage of 17.5/24kV, making it suitable for a range of medium-voltage applications.
This product features a high-performance iron core made from advanced cold-rolled silicon steel sheets. The high-voltage output of the primary winding is positioned at the top of the unit, while the secondary winding output is placed on the side for convenient wiring and integration. Its robust structure ensures reliable, long-term service in demanding power system environments.
