The gas insulated electrical gear includes at least one tank which is filled with a dielectric, gas and which is provided with a rupture disk which ruptures in the event of the dielectric gas in the tank reaching an excessive pressure so as to allow the gas to be exhausted from the tank. The rupture disk is protected against attack from the environment outside the tank by being placed inside the enclosed cabinet having an atmosphere in which temperature and humidity are controlled. The cabinet can be the low voltage and/or mechanical control supporting cabinet fitted to the electrical gear.
