Indoor HV Vacuum Circuit Breaker
An indoor high-voltage switchgear with three-phase AC 50 Hz and rated voltage 12 kV, mainly used to break and close the load current and short-circuit current of 10 kV power systems, and for the protection and control of grid equipment and power equipment in industrial and mining enterprises. Standards: GB/T 1984, GB/T 11022, JB/T 3855, DL/T 403, etc. Normal service conditions: operating altitude no more than 2000 m; ambient temperature +40 degC max, -25 degC min; daily mean relative humidity no more than 95% and monthly mean no more than 90%; seismic intensity no more than 8 degrees; suitable for places free from fire, explosion, severe pollution, chemical corrosion and violent vibration. Special conditions such as altitude above 2000 m or high humidity and sharp temperature changes require consultation with the manufacturer. As the core component of high-voltage complete switchgear, its successful development and volume production have made the company one of the few manufacturers in Sichuan with independent production capacity for the core components of high-voltage switchgear.
