FTK- 40.5(ZR) Indoor HV Vacuum Load Switch - Fuse Integrated Switchgear
Adopt miniature vacuum arc-control chamber, which improves the insulation level, andreduces theoutline dimensions.
Strong withstand voltage capacity: The whole withstand voltage could satisfy the standard of 40.
5kV GIS (Vacuum insulation distance: power frequency – 9kV/1min, and impulse – 185kV).
Adopt special spring operation mechanism, and annual, motor and remote control operation couldalso be realized.
Fuse and operation mechanism have reliable mechanical interlock. Any phase of fuse fusing, the operation mechanism operates, and the vacuum breaker opens, avoiding operation lack of phase.
Fitted with earthing switch interlocked with disconnector, which but only prevent active bay entry, but also convenient for the exchanging and maintenance of fuse.
