The LZZX-12Q current transformer is a 12kV indoor single-phase unit featuring a fully enclosed epoxy resin casting insulation structure. The design encapsulates both the primary and secondary windings, as well as the annular magnetic core, within a robust and compact resin body, ensuring excellent insulation performance and structural integrity.
With features such as lightweight construction and omni-directional installation, the LZZX-12Q is ideal for modern indoor power distribution systems. It is capable of withstanding harsh environmental conditions including humidity and pollution. The unit is widely applied for current measurement, energy metering, and protection in systems operating at 50–60Hz with a maximum voltage of 12kV.
