The LZZBJ10-24 current transformer is a 24kV indoor single-phase device featuring epoxy resin casting insulation and a fully enclosed support structure. The primary and secondary windings, along with the annular magnetic core, are securely embedded within the epoxy resin body, ensuring excellent insulation, mechanical stability, and durability.
Designed to be lightweight and support omni-directional installation, this CT can reliably operate in harsh indoor environments, including those with humidity and pollution. It is widely used for current measurement, energy metering, and protective relaying in electrical systems with a rated frequency of 50 or 60Hz and equipment voltage up to 24kV. The product meets IEC 60044-1 and IEC 61869-1 & 2 standards.
