The LDZC-10 Phase-Sequence Through-Core Current Transformer features fully enclosed secondary windings within flame-retardant plastic shells. Its primary bushing or cable passes conveniently through the inner hole, while the bottom includes installation inserts for secure and straightforward fixation. This compact and efficient design is ideal for current measurement, signal collection, and protective relaying within medium voltage cable power systems.
Designed for indoor use, the transformer supports rated secondary currents of 5A or 1A and withstands power frequency voltages up to 3kV. It operates reliably at frequencies of 50Hz or 60Hz and complies with IEC 60044-1 and IEC 61869-1 & 2 standards, ensuring safety and performance.
