bid for sf6 switchgear manufacturers in Brazil

Gas Insulated Switchgear technology uses sulfur hexafluoride (SF6) gas which has a superior dielectric properties used at moderate pressure for phase to phase and phase to ground insulation. In GIS, the high voltage conductors, circuit breaker interrupters, switches, current transformers, voltage transformers, and lightning arresters are encapsulated in SF6 gas inside grounded metal enclosures.

01/06/20058. SF6 gas leakage SF6 breakers (live and dead tank) typically have a combination of static seals (O rings and gaskets) as well as dynamic seal assemblies where the mechanism energy is transferred through to the interrupter assembly. Over time, seals degrade due to environmental conditions and exposure and will need to be replaced.
