Description

 

The LZZBJ9-10kV current transformer (CT) is an epoxy resin-cast indoor instrument transformer designed for 10kV medium-voltage power systems. It is widely used for current measurement, energy metering, and relay protection in industrial substations, switchgear cabinets, and power distribution panels.

Thanks to its compact design, excellent electrical insulation, and strong environmental adaptability, the LZZBJ9-10kV CT is a reliable choice for modern industrial automation and protection systems.

Current Transformer LZZBJ9-10 is made indoor cast-resin insulated totally enclosed structure.

It’s designed for current power measurement and relay protection in AC power system with rated frequency 50Hz, rated voltage 10kV and below.

The LZZBJ9-10kV CT plays a critical role in electrical measurement and protection in the following applications:

  • Medium-voltage switchgear (metal-clad, metal-enclosed)
  • Industrial distribution cabinets (10kV)
  • Power monitoring and SCADA systems
  • Smart substations and ring main units (RMUs)
  • Motor control centers and generator protection
  • Transformer protection systems
  • Industrial automation and relay protection panels
