Eco-efficient alternatives to insulating gas: Continuing the AirPlus

May 30, 2019 · At CIRED 2019, the world’s most important conference for medium-voltage technologies in distribution grids, ABB continues the success story of its eco-efficient insulation gases. ABB’s AirPlus™ technology is a revolutionary technology from ABB, and an alternative to sulfur hexafluoride (SF 6) gas. Four years ago, at CIRED 2015 in Lyon, France, ABB announced the world’s first eco-efficient AirPlus switchgear at the Oerlikon substation of Swiss utility ewz.

Sustainable Alternatives to sf 6 Gas within MV and HV

Aug 03, 2018 · Be part of the chalenge: propose a solution! The challenge is aimed at finding alternative solutions to the use of sf 6 gas as an insulating and/or interrupting medium within MV and HV equipment. Sulfur Hexafluoride (Sulfr hexafluoride) gas is largely used as a dielectric and insulating material in the transmission and distribution equipment. Unfortunately, insulating gas is also an extremely potent greenhouse gas with

Development Sf6 Alternative Gases in Switchgears - Switchgear

Nov 23, 2019 · An additional alternative approach is proposed to use air for insulation. The possible candidates are introduced, which are air, N2, CO2, perfluorocarbon (PFC), hydrofluorocarbon (HFC), gas mixtures containing Sulfr hexafluoride as shown in Figure 1 by boiling temperature. These gases do not have higher dielectric strength but lower GWP than insulating gas, and their boiling points are below 0 ˚C.

Histone Deacetylase (HDAC) Assay Kits

Who Studies HDACs?How Do The Kits Work?HDAC Assay Kits Are Compatible with Multiple Sample TypesHDACs, histone deacetylases, remove acetyl groups from lysine residues contained in both histone and non-histone proteins. HDACs act in direct opposition to histone acetylases (HATs). The balance of HDAC and HAT activity determines the acetylation state of lysines on proteins throughout the cell. These acetyl groups affect chromatin structure, protein stability, protein-protein interactions, gene regulation, and more. Disease models that exhibit open chromatin transitioning to closed chromatin, increased protein degradation, differential protein interacting partners, or simply show differences in gene expression, are all candidates for HDAC analysis.
