PRODUCT DETAILS Sulfur hexafluoride load
switchDescription:*FLN36-12D, FLRN36-12D sulfur hexafluoride load
switch, load switch-fuse combination, and loadable cable head load
switch are designed and developed by our company by absorbing
foreign advanced technology and combining with the operating
requirements of our country.*After comprehensive type test, the
product conforms to GB3804 "3~ 63kV AC high voltage load switch",
GB16926 "high voltage load switch-fuse combination", IEC60265,
IEC60420 standard requirements.*The product has three positions of
arc extinguishing chamber, which is reliable in interlocking , high
insulation strength at breakage, large climbing distance design,
and the outlet end is protected by voltage sharing protective
cover.* Install cable head type load switch, the outlet end of
which is equipped with touch-type cable front connector, the inlet
and outlet line is installed with high-voltage cable, and it is
equipped with cable branch (connection) box.* The switch has a
special dynamic seal and fixed seal design, reliable seal, and is
equipped with pressure gauge in obvious position. It is a new
generation of high voltage switchgear equipped with urban power
grid for operation monitoring to ensure operation safety.* This
product is suitable for three-phase AC 10KV, 50HZ power
systems, industrial and mining enterprises, high-rise
buildings, residential areas, pre-installed substation places, used
to open and close the load current, fault current, control and
protection lines and distribution transformers.1) Easy to install
the fin36-12 SF6 load switch and assembly apparatus are made into a
unique unit type (the upper part of the cabinet).and are installed
in a stacked way, which greatly reduces the difficulty of the
cabinet. Complete set of drawings for the supporting cabinet can be
provided2) Three-position switch has three positions: closing,
opening, and grounding3) There is an observation window on the end
face to observe the state of main contact and grounding contact4)
Direct-acting pneumatic arc extinguishing mode5) The sealing shell
is filled with SF6 gas as insulation and arc extinguishing
medium.6) The switch has gas filling nozzle, safety relief valve,
and SF6 gas pressure gauge.7) Manual and electric operation can be
selected.8) It is resistant to the harsh environment and has passed
condensation and pollution type tests9) You can choose the shunt
line diagram or over-current release (optional at the same
time 10) Optional moisture switch, 1 on 1 off-4 on 4 off11)
Interlocking between cabinets is optional12) Pluggable live
indication device on the operation panel is optional 13) It
conforms to GB3804 and GB16926 national standards TECHNICAL
