Gis Gas Insulated metal-clad Switchgear
1. Product Introduction
XGN49 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. It 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 switchgear is safe to use, not affected by climate, easy to install, less maintenance, less space occupied, etc. It is especially suitable for use in harsh working environment, such as humid, dusty, Sandy and high altitude areas.
