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.
