hexafluoride system Hi-pot

Partial Discharge Hi-Pot Testing can be arranged and supervision provided. Sulfur Hexafluoride (SF6) is widely used in the electric industry. It is a very stable molecule, which makes it superior to other previously used mediums due to its insulation properties, dielectric strength, and arc quenching abilities.

    Jul 18, 2018 · Apart from that, the Sulphur Hexafluoride also has a dielectric strength that is much higher than that of an air circuit breaker. This allows it to break or interrupt currents of a much larger voltage. If that isn’t enough, the Sulphur Hexafluoride gas allows for silent operation. Typically, other circuit breakers tend to emit some noise.
