Product Description
Product Overview
HCM-12 (24) SF6 fully insulated, fully enclosed, common box compact medium voltage series ring main unit (hereinafter referred as RMU). The switchgear and main busare sealed in a shell filed with SF6 gas, which is fully insulated, fully sealed, expandable and easy to combine. Each SF6 insulated gas box can be arbitrarily expanded on the left and right sides . The explosion-proof channelat the bottom of the gas tank is equlpped with an explosion-proof dlaphragm to prevent the damage ofhigh-pressure gas to people, cables and other switchgear in the substation effectively.
