Overview
SDF disconnectors are available for up to 550 kV, 4000 A and 63 kA. These types 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.
