Siemens to provide UK’s first sf6 gas free 145kV vacuum circuit

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 insulating gas which has traditionally been the method of insulation in high voltage switchgear since the 1960s. The chemical properties of sf6 gas gas make it ideal for electrical insulation and arc quenching in high-voltage switchgear.Get price

sf6 gas gas - WIKA Singapore

The 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 gasGet price

Switchgear - Wikipedia

Typically, switchgear in substations are located on both the high- and low-voltage sides of large power transformers. The switchgear on the low-voltage side of the transformers may be located in a building, with medium-voltage circuit breakers for distribution circuits, along with metering, control, and protection equipment.Get price
