The HYJL-12 high voltage metering cabinet (box), also referred to as a floor-type metering box, is designed for AC three-phase 50Hz power systems with a rated voltage of 10kV. It is used for high-voltage cable incoming and electric energy metering at the user side, and can be installed in industrial parks, residential communities, and industrial or mining areas. The floor-type structure allows operators to open the cabinet door for meter reading and local circuit breaker switching, making operation and maintenance more convenient.
