WebVFI vacuum switchgear provides fault interruption and convenient load switching for 15-, 25- and 35 kV underground systems. VFI switchgear is designed for outdoor mounting on a concrete pad. SF6 insulation provides a compact, low-profile installation. Power is fed to and from the switchgear from underground through openings in the pad. WebConfirm that the contacts have closed and opened by A.The OPEN/CLOSE position indicator, or B.By a continuity check between the switch terminals. 3.Test manual open and close.Using a hotstick, pull the yellow manual OPEN handle to open the switch contacts.
