Power factor testing of sf6 gas circuit breakers | TD Guardian

The insulating material used in the manufacture of modern insulating gas gas circuit breakers is synthetic, which have no capacitor characteristics and have no ability to absorb moisture. The main insulating materials are Synthetic filament wound epoxy insulating tubes, Hollow core insulators (porcelain or composite), and the sf6 gas gas itself. All sf6 gas breakers are sealed and incorporate a molecular sieve type desiccant to maintain moisture to extremely low levels.
