SafePlus Secondary Gas Insulated Switchgear | ABB US uses SF6 (Sulfur hexafluoride) as an insulation and quenching medium. The SF6 is contained in a welded, stainless steel, sealed-for-life enclosure with an operating lifetime better than 30 years. The leakage rate is less than 0.1% per year! The switchgear is type tested according to ANSI/IEEE C37.20.3, C37.58, C37.54, and UL listed.
SF6 gas - WIKA United Kingdom plant safety of SF 6 gas-insulated switchgear is reduced significantly through low concentrations of decomposition products. These decomposition products arise during operation through arcing in moist or impure SF 6 gas. In order to detect even the smallest leakages or to warn ahead of gas emissions, we have a range of high-quality gas ...
US6004377A - System for collecting and refining SF6 gas ... 6 gas is collected from the inside of a gas insulated machine during maintenance and inspection and is refined. Compositions of the refined SF 6 gas are analyzed and confirmed to be reusable at the site. In the process of SF 6 gas collecting and refining, acidic gases are neutralized and removed by a dry method using filters and the refined SF 6 gas is collected in a collecting tank.

Efacec Launches New Switchgear at CIRED | T&D World transformers are a critical component of today's electricity systems. They "step down" the voltage from the primary distribution system to levels that can be used by residential and commercial customers. Like other electrical devices, transformers only function for so long. An average transformer can function between 25 to 40 years.
