  • Sulfur Hexafluoride (SF6) discovered in 1900 by Henri Moissan
  • In 1937 it was discovered that SF6 possessed a much higher dielectric strength than air
  • Major supplier Allied Signal (Silver Bottle) began processing SF6 gas in 1948

Electrical Applications

  • Circuit Breakers 345-500 kV
  • Puffer Breakers – SF6 used in place of air, oil or vacuum
  • Switches 7.5-35 kV
  • Gas Insulated Transmission Lines
  • Mini Substations; space requirements are as little as 10-20% of air-insulated substations

Non-electrical Applications

  • Magnesium Casting
  • Aluminum Degassing
  • Leak Detection
  • Particle Accelerators (Universities)
  • Window Pane Insulation
  • Nike-Air Shoes

SF6 Characteristics

Sulfur Hexafluoride has a unique combination of physical and electrical properties:

  • Chemical Inertness
  • Thermal Stability
  • Non-toxicity
  • Excellent Heat Transfer
  • Non-flammability
  • High dielectric/breakdown strength
  • Non-corrosive
  • Ability to regenerate

SF6 a Greenhouse Gas

Sulfur Hexafluoride is a fully fluorinated compound (FFC), and since FFC’s have lifetimes of up to 50,000 years in the atmosphere, these powerful greenhouse gases can add a lot to global warming if emissions are allowed to continue to grow.

For example, SF6 has almost 25,000 times more global warming potential than CO2!!
