8DJH Secondary Distribution Gas Insulated Switchgear
Basic Info
Model No.: 8DJH
Product Description
8DJH Secondary Distribution Gas Insulated Switchgear
8DJH secondary distribution gas insulated switchgear is the world's current voltage class in the most compact structure of the product, light weight, small volume, high economy.Due to these characteristics, our 145kV GIS meets all environmental requirements for high voltage combination appliances.Because noise and electric field emission are particularly low, it can be installed in very sensitive environments such as residential areas and urban centers.
