3.3kV-27kV Embedded PoleVacuum Circuit Breaker
Introduction
SecoVac series 3.3kV-27kV vacuum circuit breaker designed byGE is a three-phase AC indoor breaker with 3.3kV-27kV ratedvoltage and can be applied in controlling and protecting electricalequipment in industrial and mineral enterprises, power plants andsubstations.
Leading vacuum andinsulation technology
GE has developed environmentallyfriendly vacuum circuit breakers whichare capable of reliably switching highstress fault currents. Increased dielectricstrength of the SecoVac circuit breakeris achieved through encapsulation ofthe vacuum interrupter in epoxy resinmaterial. SecoVac circuit breaker familyutilizes this solid insulation technologythat has been catering to a wide scope ofapplications for years.

High adaptabilityCompare to traditional design,enhanced reliabilityLess resistanceLess mechanical parts.
The state-of-the-art processing and advanced quality control
The high quality of the embedded pole is achieved by using the latest APG (Auto PressureGelation) technology and advanced vacuum mixing and degassing technology. TheVogel clamping machine is an essential piece of equipment to ensure the mechanicaland insulating strength of the embedded pole of 3.3kV-27kV series MV embedded polevacuum circuit breaker.
As well as the processing facilities, the testing facilities are also very important to thequality control of the breaker. In the manufacturing process of SecoVac, from incoming.
Every embedded pole goes through the following inspection and testing before it isallowed into the breaker assembly line:X-ray inspectionPower frequency withstand voltage testPartial discharge measurementThermal cycling test.
