Abstract
A gas-insulated switchgear apparatus comprising two power-receiving units with a cable head on power-receiving side, a wattage metering unit, and two lead-out units with a cable head on lead-out side. The two power-receiving units are arranged on one side of the wattage metering unit, and the two lead-out units on the other side. The gas-insulated switchgear apparatus is thus simplified, electrical connection facilitated between the units, and the floor space of the whole apparatus reduced.
