Outline & Mounting Dimensions
TheLZZBJ9‑10 10kV indoor cast resin current transformeris a high‑voltage measurement device designed for medium‑voltage indoor switchgear and distribution systems. It steps down primary current into a safe, standardized secondary current, enabling accurate metering, protection, and monitoring of electrical circuits in industrial and commercial facilities.
This current transformer usescast resin insulationto provide excellent dielectric strength, moisture resistance, and long‑term stability, making it suitable for transformer substations, ring‑main units, and compact switchgear. It is widely applied in power distribution, industrial plants, data centers, and commercial buildings where reliable current sensing and protection are required.
Manufactured to international standards, the LZZBJ9‑10 10kV current transformer features a compact design, low-loss core, and low phase angle error for high measurement accuracy. It supports multiple transformation ratios and mounting configurations, and can be customized for special requirements.
Available through a global network ofsuppliers, manufacturers, wholesalers, and dealers, this unit offersOEM/ODM support, low MOQ, and wholesale pricing, making it ideal forindustrial users, commercial users, electrical contractors, and distributorswho need reliable, factory‑direct indoor current transformers for medium‑voltage systems.
