Fire-Rated Switchgear
Which places require Fire-Rated Switchgear?
Fire-Rated Switchgear (also known as Fire-Resistant Switchgear or Fire-Resistant Distribution Cabinets) are specially designed electrical enclosures. Their core function is to maintain the normal operation of internal electrical equipment for a specified duration (typically 30 minutes, 60 minutes, 90 minutes, or 120 minutes) during a fire, while preventing flames and hot gases from propagating through the enclosure to other areas. This provides critical time for personnel evacuation, firefighting operations, and the continued operation of essential equipment.

Gas-Insulated Switchgear (GIS)
Gas-Insulated Switchgear (GIS) for High-Altitude Applications
For Gas-Insulated Switchgear (GIS), since the main live circuits are enclosed within sealed, gas-filled compartments and external connections utilize solid insulation, the insulation performance is unaffected by atmospheric pressure. The primary consideration for GIS at high altitudes is the mechanical strength of the gas enclosure (gas compartment).
