Ⅰ. Classification of IEEE Bushing
1. Loadbreack Reducing Tap Connector
600A/200A Loadbreack Reducing Tap Connector is used to connect 600AT-type connectors or 600A extension pipes. It provides a 200A interface for 600A systems and can be connected to 200A elbow connectors. The elbow arrester can be plugged and unplugged under 200A load and serves as a load switch. Used to form a T-II connector with a T-shaped connector.
2. Bushing Well
The bushing well is used in the high-voltage connection of the American box-type box transformer or ring main unit. The bushing well is fixed on the box body with a pressure ring fixing device to connect the 200A bushing insert, which is suitable for transformer oil medium.
3. Reducing Tap Connector
Loadbreack Reducing Tap Connector is used to connect 600AT-type connectors or 600A extension pipes. It provides a 200A interface for 600A systems and can be connected to 200A elbow connectors. The elbow arrester can be plugged and unplugged under 200A load and serves as a load switch. Used to form a T-II connector with a T-shaped connector.
4. Loadbreak Bushing Insert
Loadbreak bushing inserts help in loadbreak switchgear. They let you connect or disconnect lines while keeping the power on
