  • Vacuum Test Chambers for SF6 Leak Testing - DILO

    We recommend this model range where larger components need to be tested or where integrated gas handling in the test chamber is required. In this case, the test objects are filled with SF 6 in the chamber. Gradual evacuation and filling of the test objects is also possible in order to avoid an inadmissible differential pressure between the test object and chamber.

  • SF6 gas in medium-voltage switchgear | TD Guardian Articles

    SF6 has been used extensively in non-electrical applications. Since SF6 is inert, it is very attractive to the magnesium industry. Magnesium reacts spontaneously in the presence of oxygen, so a heavier-than-air cover gas is used to isolate the molten magnesium from oxygen as the magnesium cools.

  • Gas Handling System - MSE

    The SF6 gas handling system allows to transfer the SF6 from the accelerator to the buffer tank and conversely. But it also allows to dry and clean the gas when there is suspicion of contamination. Older gas handling systems work with an oil vacuum pump and compressors where the oil is in contact with the SF6. This leads inexorably to oil contamination of the SF6 and less insulation capability of the gas.
