Load Break Switch,high voltage vacuum load switch, indoor high voltage AC load breaker switchFLN36-40.5 Indoor load break switch (LBS) 40.5KV

FLN36-40.5 Indoor load break switch (LBS) 40.5KV

FLN36-36 an indoor high-voltage SF6 load switch, with the rated voltage of 36kV.

Adopted with SF6 gas as an arc-extinguishing and insulation medium, including the three contactors for switching-on and switching-off and to-ground, and is characteristic in its small volume,its convenient installation and operation and its the great adaptability with surroundings.

FLN36-36 of an indoor high-voltage SF6 load switch and FLN36-36D of SF6 load switch plus

fuse combination can function to protect and control the electric equipments for power supply

and transformer substations especially being suitable for ring net cabinet, cable branch

cabinet and distribution switching substation. FLN36-24of an indoor high-voltage SF6 load

switch and FLN36-36D load switch plus fuse combination are complied with the standards

of IEC60265-1-1998, IEC60420 etc.

Environment condition

  1. The altitude: under 1000M.
  2. The ambient temperature: -25℃-+40℃.
  3. The relative humidity of air: monthly≤90%, daily≤95%.
  4. Amplitude: Earthquake degree 8.
  5. Application occasions should free from fire, inflammables, explosives, corrosives and severe vibration.
