Overview
FLRN36-12, with rated voltage of 12kV , is a kind of SF6 gas insulated load break switch(LBS) combination with fuse
Product Details
Description:
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.
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.
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.
