ABB IEC Live Tank Vacuum Mechanical Circuit Breaker OVB-VBF

share

Vacuum Circuit Breakers OVB-VBF are used in distribution systems ratedat at 24 / 36 / 40.5 kV and are of live tank design. The vacuum interrupters are housed in hollow porcelain insulators filled with SF6/Nitrogen gas at 0.5 bar above atmospheric pressure to safeguard against condensation. A spring operated mechanism is housed in a weather-proof cabinet and a sturdy extruded steel angle structure is used for mounting the breaker.
