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 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 system, as 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.
