SF6-alternative gases maintenance systems station

Aug 23, 2010SWITCHGEAR WITH SF6 GAS There are three principal designs for SF6-insulated switchgear. With the first two, known as controlled pressure systems and closed pressure systems, release of SF6 is unavoidable in practice. This is because the systems require maintenance in the course of their service life, at which point leakage occurs.
