++++GeneralFLBS an indoor high-voltage SF6 load switch, an
switchgear with the rated voltage of 12kV/24kV, 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.FLBS of an indoor high-voltage SF6 load switch and
FLBS 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.FLBS of an indoor high-voltage SF6 load switch and FLBS
load switch plus fuse combination are complied with the standards
of GB3804-1990, IEC60256-1,1997, GB16926, IEC60420 etc..++++Service

Maintenance & Service.++++Installation, AdjustmentFLBS
type load break switch has been strictly tested before outgoing
from the factory, and fully meet the technical standards, must
carefully read the installation manual and prepare as below before
the installation and adjustment.Check the external appearance, any
damage product is not allowed to use.Clean the equipment and get
rid of the dust and dirt may cause by the transportation or other
causes.After installation, be sure the load break switch is turned
off, insert the handle to the earthing operating hole in the up
part of operating panel, and rotate the handle clockwise in
180o to earth the switch, rotate counterclockwise in
180o to switch off the earth.For switching on, turns off the
load break switch firstly, insert the handle to the load break
switch operating hole in the lower part of panel and turn on the
load switch.From the switch on to switch off, for K type
mechanism, insert the handle to the load switch operating hole and
rotate it in 180o to switch off; for A type mechanism,
press the "switch off" button to switch off the load break switch,
observe from the winder to confirm it, check whether the on/off
indication plate works properly.Notice: only when the load break
turns off, can turning on and earthing operation be done
!++++Maintenance & ServiceOn condition of installing in
environment as this manual required and normal operations, product
guaranteed to be fault free for 10 years and has a running
life of 25 years, but regular check per 6 months is
required.Keep the external appearance away from dust, dirt and
damp.Lubricate and operate the mechanism for 3-5 times, check
whether it acts properly.Check with the pressure meter regularly,
in case of meter data lower than 0.01MPa, should reload gas.When
the malfunction happens in the load break switch and fuse
combination, and one of the three phase immediately, gas charging
should be done by professional personnel from or trained by the
manufacturer. uses burns out, all three fuses should be replaced at
one time, must earth the switch before the replacement.++++Matters
need attentionIt is NOT allowed to disassembly the self-sealed
valve in front of switch( connecting end of meter).It is NOT
allowed to unload the seal screws on switch at any
time.+++Packaging & Shipping +++++About UsFounded in
