LMZC4-10 air-insulated ring main unit dedicated high-voltage 10KV core-penetration current transformer with current ratios of 50/75/5

Piercing-core current transformers (also known as high-precision current transformers) are suitable for energy metering in AC power systems ranging from 10KV to 35KV. They offer high-accuracy limiting protection and current measurement. This series of current transformers is specifically designed for metering and high-limit protection of incoming cables in ring main units and switchgear rooms, serving as an alternative to high-voltage busbar type metering transformers (LZZBJ, LFS series). The product is compact, with high metering accuracy (0.2S class), and is classified as a full-condition product capable of operating in various environments. It is a maintenance-free product that can reduce equipment space, lower costs, and improve reliability. It is applied in fully insulated and sealed compact systems such as Safeplus.SM6, 8DH, FB, GA/GE, SS, FIT, etc. Based on different current ratios, accuracy levels, and rated loads, this series of transformers is divided into several models. Specific parameters are detailed in the corresponding parameter tables for each model.
