ZW32-12 outdoor AC high voltage vacuum circuit breaker is post structure with separated three phases. Vacuum arc extinguishing chamber is packed by silicone rubber and then installed in the insulation sleeve with the primary conductive elements. The insulation sleeve is installed on the completely sealed enclosure. In the enclosure, there are mechanism, driving medium, secondary elements and other accessories. ZW32-12 vacuum circuit breaker is of excellent sealing, small size, cold- resistance, high-temperature-resistance, wind and sand resistance, damp-proof, condensation-proof. It is intelligent, reliable, maintenance free, suitable for servicing in rugged environment.
