Production of 120-204kV Tank Type Vacuum Circuit-Breakers (VCBs)

摘要

We worked on the Research and Development (R&D) program to realize higher voltages for Vacuum Circuit-Breakers (VCBs). In the 1970s, we developed and commercialized 84kV single-break and 168kV double-break tank type VCBs. Recently, we have developed 120kV to 204kV tank type VCBs to realize compact design, high performance, and lower lifecycle cost. These VCBs are made on the basic design of our 72/84kV tank type VCBs with rich supply records. These VCBs use the latest vacuum interrupters with the latest axial magnetic field electrodes. As a high-voltage class tank type VCB, we were the first company ever commercialized these products. Using VCBs for higher voltages and larger capacities applications is a worldwide trend and our models are getting increased recognition.
