sf6 Disposal for substation

Apr 28, 2008 · Although SF6 is non-toxic and non-flammable on its own, when used as a circuit-interrupting medium it can produce a number of dangerous and toxic decomposition products. This calls for special precautions when working on any SF6-filled equipment. Even more serious is the issue of disposal at the end of equipment life.

  • Gas-Insulated Substations - GIS

    A gas-insulated substation (GIS) uses a superior dielectric gas, SF6, at moderate pressure for phase-tophase and phase-to-ground insulation. The high voltage conductors, circuit breaker interrupters, switches, current transformers, and voltage transformers are in SF6 gas inside grounded metal enclosures. The atmospheric air insulation used in a conventional, air-insulated substation (AIS) requires meters of air insulation to do what SF6 can do in centimeters.
