The LZZBJ9-36 current transformer is a 36kV indoor single-phase unit featuring epoxy resin casting insulation and a fully enclosed support construction. The primary and secondary windings, along with the annular core, are securely encapsulated within the epoxy resin body, providing robust electrical insulation and mechanical strength.
Designed with a large creepage distance on the outer insulation surface, the LZZBJ9-36 effectively withstands pollution and humidity, ensuring reliable operation in harsh indoor environments. It is widely used for measuring electric capacity, current, and for protective relaying in 36kV power systems. The product complies with IEC 60044-1 and IEC 61869-1 & 2 standards.
