SF6: The Perfect Gas for the El Paso Utilities Industry


SYOXSA, Inc. seen as a key provider of dielectric gases – also called insulating gases – for the El Paso electrical utilities industry. Such gases are used most often to either avoid or quickly tamp down electrical discharges, for which their dielectric attributes render them perfect. The most important of these gases and the one most sought from us is sulfur hexafluoride (SF6).

Utilities use SF6 to electrically insulate high-voltage transformers, sulfur hexafluoride circuit breakers, switchgear, and other equivalent sorts of devices.

Where SF6 circuit breakers are concerned, they’re pretty much singularly taking the place of oil-filled circuit breakers (OCBs), which, due to the fear of their containing now-banned, environmentally toxic polychlorinated biphenyls (PCBs), have fallen out of favor.

The predominant use of SF6 under pressure in gas-insulated switchgear is due to its manifesting a dielectric strength significantly higher than air or dry nitrogen (the latter one more gas used almost universally by our utilities industry customers).

One important perk of SF6’s high electronegativity and density is that it permits the utilities industry to reduce the size of electrical gear. This makes it possible to install such gear in more-manageable indoor environments, instead of air-insulating it outdoors. Gas-insulated devices placed indoors is, of course, less likely to be affected by climate and pollution. What’s more, a controlled environment also helps assure greater system trustworthiness and longevity.
