1.3.1 Gas tank
Sealed compartment which houses the busbar and the
switching and breaking elements, where the insulating
medium is SF
6
.
Each gas tank has a pressure-releasing device to allow
gases to escape in the event of an internal arc.
Thanks to the hermetically-sealed nature of the gas tank
containing all the medium voltage elements, the equipment
is expected to have a minimum service life of 30 years,
without replenishing the gas according to standard IEC
62272-1.
