insulating gas Transmitter - Draeger

Increased safety, cost reduction and climate protection. When insulating switchgear or transformers, sulfur hexafluoride (sf6 gas) is used. Since it is technically almost impossible to hermetically seal these systems, emissions can escape into the environment. Gas detection systems from Dräger make it possible to detect even the smallest leaks at an early stage and initiate corrective measures.Get price

Precision plasma etching of Si, Ge, and Ge:P by insulating gas with

The impact of the O2 content in insulating gas-O2 gas mixtures on the etch rate and sidewall profile of silicon (Si), germanium (Ge), and phosphorous doped germanium (Ge:P) in reactive ion etching has been studied. The characteristics of etch rate and sidewall profile are greatly affected by the O2 content. Below 50% of O2 content, a large variation in Ge etch rates is found compared to that of Si, but for O2 content above 50% the etch rates follow relatively the same trend.Get price

Aug 06, 2020In 2019, Siemens launched the UK’s first ‘clean air’ insulated switchgear. It was the first time that clean air has been used instead of insulating gas to insulate 145kV circuit breakers in the UK. It uses a gas mix similar to the air we breathe, made up of nitrogen (80%) and oxygen (20%), as a carbon free alternative to sf 6. Get PriceGet price
