Vacuum and filling switches with SF6 gas

The applied technology allows the following operations to be carried out: Check the degree of sealing of the component, subjected to testing in conditions similar to those of operation, introducing tracer gas (helium gas) inside the component itself and searching for any leaks towards the external environment. Determine by means of a threshold value whether the component is gas-tight and therefore suitable for use. Fill the component using Sulfur Hexafluoride (SF6 gas) at the pre-set pressure (this occurs only if the component has passed the leak test, cited above, with a positive result).
