The SDF disconnectors are available up to 550 kV, 4000 A and 63 kA. These type of disconnectors have a low friction design and offer minimized contact resistance. They are equipped with dead center interlocking for reliability in extreme conditions. Some other important features of these disconnectors are:
- No external spring in contact fingers
- Superior design of mechanical interlock
- Strong rotary pedestals
- Ice breaking capacity
Applications
The horizontal center break disconnector is used at substations due to its simplicity and flexibility in arrangement.
