The JDZ18-10R Voltage Transformer features a fully enclosed epoxy resin casting construction, ensuring high insulation performance and excellent environmental resistance. Designed for indoor applications, it is used for measuring voltage, electric energy, and providing protective relaying in single-phase or three-phase AC circuits. The transformer operates at 50Hz or 60Hz and is suitable for systems with a maximum equipment voltage of 12kV.
With its low magnetism iron core, the JDZ18-10R minimizes energy loss and enhances measurement accuracy. The product also offers a large creepage distance on the external insulation surface, improving resistance to dirt and moisture. Its compact, maintenance-free structure makes it ideal for reliable and long-term performance in medium-voltage switchgear systems.
