Home / Arrangement of small busbars in 10kV high-voltage switchgear
A sectionalizer allows the station to be split into two separate parts and the parts to be disconnec.
Common characteristic features of switchgear installation Because of its small size and outstanding compatibility with the environment, SF6-insulated switchgear (GIS) is gaining con-stantly on other
