Gas tank
This is a sealed compartment, made of stainless steel and
sealed for life, which houses the switching and breaking
switchgear, with gas as insulating medium.
Depending on the function for which the cubicle was
designed, it may contain the following components:
• Busbar disconnector.
• Grounding disconnector.
• Internal busbar and connections.
• Vacuum interrupter.
• Switch - disconnector.
• Fuse holders.
Connection to the busbar is possible via upper bushings.
Connection to the medium voltage cables is made with the
lower bushings.
The gas pressure is tested, in each cubicle visually by means
of a pressure switch with a volt-free contact, allowing it to
be used as a remote alarm or blocking/trip for the position.
