The JDZV18-10R Voltage Transformer adopts an epoxy resin casting and fully enclosed construction, offering excellent insulation and environmental protection. Designed for indoor applications, it is used for measuring voltage, electric energy, and providing protective relaying in single-phase or three-phase AC circuits. Operating at a frequency of 50Hz or 60Hz, it supports systems with a highest voltage rating of 12kV.
This voltage transformer features high reliability, low magnetic flux density in the core to reduce energy loss, and a large creepage distance that enhances external insulation. With a compact, durable, and maintenance-free design, it is ideal for long-term operation in medium-voltage indoor switchgear systems.
