Outline & Mounting Dimensions

JDZ10 Single Phase

TheJDZ10‑3, 6, 10 (A, B) Single‑Phase Fully Enclosed Fully Insulated Casting Voltage Transformer (HT PT)is a compact, high‑voltage transformer designed for accurate voltage measurement and safe isolation in medium‑voltage power systems. It steps down primary high‑voltage signals (3 kV, 6 kV, or 10 kV) to a standardized low‑voltage secondary output, enabling safe connection to meters, relays, and protection devices.

This fully enclosed and fully insulated casting transformer is encapsulated in epoxy resin, providing excellent moisture resistance, mechanical strength, and long‑term insulation performance, making it suitable for harsh industrial environments and indoor switchgear installations. It is widely applied in industrial power distribution, commercial buildings, substation metering, and protection schemes, where reliable and stable voltage sensing is critical.

As a specializedmanufacturer and supplierof high‑voltage transformers, we offerOEM/ODM, custom configurations, low MOQ, and wholesale pricingforindustrial users, commercial users, electrical contractors, and distributors. Our products are produced in modern factories and shipped through a network ofwholesalers and dealers, ensuring fast delivery and technical support for bulk projects.
