If the name sounds familiar, it’s normal. The VOX has been commercialised for more than two decades by Areva and Schneider Electric.
We, at CO7 Technologies, purchased the intellectual properties and assets for the VOX. The intent for us is to focus our efforts in developing and expending the VOX family. In January 2021, we will then move the production line from Schneider, Germany to our state-of-the-art facility in Montreal.
VOX combines the best new and proven technology for outdoor distribution applications up to 38 kV.
CO7 Technologies’ latest range of vacuum interrupters are housed in a fully welded, sealed-for-life, stainless steel tank, providing a controlled gas insulated environment totally immune from external ambient conditions. A spring charged mechanism provides manual or motorized circuit breaker operation.
VOX has been designed and tested to meet the requirements of the relevant applicable IEC, BS, AS, ANSI, IEEE, GOST and GB standards.
