Secondary switchgear 8DJH 24

medium-voltagegas-insulatedcircuit breaker

The 8DJH 24 is a gas-insulated switchgear using F-gas-free Clean Air. It delivers proven reliability and a maintenance-free design for medium-voltage systems. Siemens’ 8DJH 24 blue GIS is a gas-insulated medium-voltage switchgear for secondary power distribution systems up to 24 kilovolts. It uses Clean Air, an insulating medium that consists of natural elements free of fluorinated greenhouse gases (F-gases), to enable safe, sustainable operations. The gas-insulated switchgear’s blue switch, a three-position switch-disconnector with a vacuum interrupter in the secondary path, does not produce any toxic decomposition during the switching process. This allows the dielectric strength of the gas to remain constant throughout the entire service life for environmentally friendly disposal at the end of its lifecycle. The 8DJH 24 blue GIS provides reliability and simplicity in a smart, innovative design. It has been an integral part of the secondary medium-voltage portfolio at Siemens for more than ten years.
