Overview:
The FLN36 SF6 gas-insulated load break switch is a dual-break rotary switch that utilizes sulfur hexafluoride gas as the insulating and arc-extinguishing medium, designed for 7.2-24kV XGN15-12 RMU distribution systems. Each load break switch is filled with SF6 gas at a pressure of 0.4 bar, with the gas permanently sealed inside.
