Overview of our live tank circuit breakers
We offer our live tank circuit breakers for applications from 72.5 kV to 800 kV, up to 80 kA. Depending on the requirement, you can choose from live tank circuit breakers with three-pole (one drive for three poles) or single-pole (three drives for three poles) operation, as well as from porcelain or composite insulators. Our live tank circuit breakers are suitable for all different types of applications, from use in extreme temperatures to earthquake regions. In these circuit breakers, the interrupter unit is not grounded during operation – it is exposed to high voltage.
Main features:
•For applications from 72.5 kV to 800 kV, up to 80 kA
•Spring drive mechanism (3AP) or electrohydraulic operating mechanism (3AT)
•Self-compression principle (≤ 245 kV) or dynamic self-compression principle (≥ 245 kV)
•Available with single- (FI, FE) or three-pole operation
•Suitable for temperatures from -60 up to +55°C
•Available with porcelain or composite insulators
