The LDZB6-12 current transformer is a 12kV indoor single-phase device featuring epoxy resin casting insulation and a fully enclosed support structure. Its design integrates the primary and secondary windings with the annular magnetic core into a compact resin-molded body, ensuring high dielectric strength and excellent mechanical reliability.
With its lightweight construction and support for omni-directional installation, the LDZB6-12 is ideal for compact switchgear applications. It performs reliably in harsh indoor environments, including high humidity and pollution. The unit is widely used for current measurement, energy metering, and protective relaying in systems operating at 50Hz or 60Hz, and complies with IEC 60044-1 standards.
