Description
FKN12A- 12D Series air- blast load break switch and FKRN12A- 12D series air- blast load break switch-fuse combination apparatus are new series switchgear applies to three- phase electric distribution system of rated 12KV, acting as protecting and control apparatus for transformers, cable and overhead wiring. These series are especially applicable in rural, urban terminal substation and prefabricated substations, as well as ring network power supply.
FKN12A- 12D series Load Break Switch can break and make load current and over-current. FKRN12A- 12D series air- -blast Load Break Switch can break and make over-current, load current and short-circuit current (limited current fuse).
Environment condition
- Ambient temperature: -45℃~+40℃
- Altitude: ≤3000m
- Relative humidity: monthly average ≤90%; daily average: ≤95%
- Wind pressure: ≤700Pa (equals to wind speed 34m/s)
- Air contamination degree: IV degree
- No corrosive or flammable gas
