Get PriceAbstract. SF 6 as insulating gas has a very good dielectric strength. Therefore, SF 6 is used in many applications. Nowadays, it is investigated again whether SF 6-N 2 mixtures can replace pure SF 6 in for example gas-insulated substations and lines. For pure SF 6 the optimal gas pressure varies between 4 and 6 bar. In order to find a suitable SF 6-N 2 gas mixture to substitute SF 6, the gas
