CT68 Vacuum Circuit Breaker Operating Mechanism
CT68Vacuum Circuit Breaker Operating Mechanism
Description
The CT68 vacuum circuit breaker operating mechanismprovided by MindeElectrical is a qualitymachinery designed and developed based on world-class advanced technology. It can not only be matchedwith the Chinese ZN12-12, ZN12-40.5, ZN12-27.5, and ZN68A-12 indoor high voltage vacuum circuitbreakers but also cooperate with similar circuit breakers in other countries.
Product Features of the CT68 VacuumCircuit Breaker Operating Mechanism
This spring operating mechanism enjoys a compact structure, extended service life, great breaking capacity, richfunctions and easy maintenance. Hence, it has been widely used in the power network, petrochemical industry,metallurgy industry, mining industry and so on.
AmbientConditions
1. Surrounding air temperature: -45°C to 40°C;
2. Altitude: under 2000m; windspeed: under 35m/s;
3. Relative humidity: under 95%(daily average), 90%(month average);
Vapor pressure: under 2.2Kpa (dailyaverage), 1.8Kpa(month average);
4. No frequent serious vibration, water vapor, gas, chemical corrosive deposit,salt mist, dust, fire nor explosive materials which substantially undermine themechanism’s performance.
