The XGN49-40.5 C-GIS Gas Insulation Cabinet Metal-clad Switchgear is safe to use, not affected by climate, easy to install, less maintenance, less space occupied, etc.
1. Introduction of XGN49-40.5 C-GIS Gas Insulation Cabinet Metal-clad Switchgear
XGN49 Series & XGN75 Series indoor gas insulated metal-enclosed switchgear (hereinafter referred to as “switchgear” or “C-GIS”) is a kind of composite apparatus which seals all the main circuit switches in a metal enclosure and uses SF6 gas as arc-extinguishing and insulation medium. XGN49-40.5 C-GIS Gas Insulation Cabinet Metal-clad Switchgear is suitable for three-phase AC single-bus and double-bus power systems with rated voltages of 12-40.5 kV, such as power plants, substations, rail transit, factories and box type substations, used for controlling, accepting and distribution the energy.
The XGN49-40.5 C-GIS Gas Insulation Cabinet Metal-clad Switchgear is safe to use, not affected by climate, easy to install, less maintenance, less space occupied, etc. XGN49-40.5 C-GIS Gas Insulation Cabinet Metal-clad Switchgear is especially suitable for use in harsh working environment, such as humid, dusty, Sandy and high altitude areas.
