10kv 12kv Disconnector On-load Switch High Voltage Air Pneumatic Switch Load Break Switch

 

10kv 12kv Disconnector On-load Switch High Voltage Air Pneumatic Switch Load Break Switch

 

FKN12-12D/630-20 indoor AC high-voltage load switch is a three-phase high-voltage switchgear with a rated voltage of 12KV and a rated frequency of 50HZ. It is used for switching load current, closed-loop current, no-load transformer and cable charging current, off combined short-circuit current. The load switch equipped with the grounding switch can withstand short-circuit current.
FKN12-12R.D/100-31.5 type indoor AC high voltage load switch-fuse combination is an indoor high voltage switchgear that combines FKN12-12D load switch and XRNT port-12 high voltage current limiting fuse. It can reliably break any current up to the short-circuit current: the load switch breaks the working current, the fuse breaks the short-circuit current, and jointly breaks any overcurrent between the working current and the full short-circuit current, and the fuse makes The load switch is open.

 

Normal working environment
1. Ambient air temperature: upper limit: +40°C, lower limit: -25°C.
2. Altitude: The altitude is 1000m and below.
3. Relative humidity: the monthly average is not more than 90%, and the daily average is not more than 95%.
4. The surrounding air should not be obviously polluted by corrosive or flammable gas and water vapor.
5. No frequent strenuous exercise. 6. Anti-pollution grade: Class II.

 

PS: Products with special requirements, specifications and dimensions that need to be improved can be designed and manufactured according to user requirements.
