Product Description

Product Description

15kV Indoor SF6 Switch-Disconnector FL(R)N36 Load Break Switch (LBS) is a rotary load switch using SF6 gas for insulation and arc extinguishing, designed for 15kV power distribution systems. Each unit is sealed with 0.4bar SF6 gas and can be installed vertically or horizontally. A common installation in ring main units involves a horizontal steel partition between the cable and busbar rooms, ensuring safety during operation and maintenance.
Combining the FLN36-15 indoor high-voltage SF6 load switch with other electrical components allows for control and protection functions, ideal for industrial and mining enterprises, civil power supply, and secondary substations. The FLRN36-15kV load switch-fuse combination is particularly suited for ring network power supply units, matching transformer protection characteristics.
