sf6 gas: sf6 gas insulated circuit breakers are the main type of breaker installed in transmission networks today and the only current style of breaker being manufactured for EHV applications. Sulphur hexafluoride (sf 6) is an inert, heavy gas with good dielectric and arc extinguishing properties. The dielectric strength of the gas increases with pressure.
[email protected]4/11/2020The good news is that through the collective RD of experienced switchgear manufacturers and other experts, today power utilities have several alternatives to gaz sf6. There are three main alternative approaches to gaz sf6 replacements in play today: based on 3M Novec 5110 Insulating Gas which is a C5-Fluoroketone; based on 3M Novec 4710 which is a C4
