sf6 switchgear joints for Maintenance

Finally, SF6 switchgear must have a tank design capable of withstanding pressure differences caused by temperature variations. This can substantially increase the weight of switchgear. Solidly insulated reclosers were developed during the 1990s as a competitive response to the problems affecting SF6 switchgear.
