Using SF6 gas as both the insulation and arc extinguishing medium, the FLN36 integrates load switching, isolation, and grounding functions in a compact sealed structure. It is widely used in ring main units (RMU), compact substations, cable distribution cabinets, and medium voltage switchgear systems.<\/p>\n<h2 data-section-id=\"736h55\" data-start=\"542\"

Principle<\/h2>\n<p data-start=\"1584\" data-end=\"2018\">The FLN36 load break switch adopts SF6 gas as both insulating and arc-quenching medium. During switching operations, the contacts open inside the sealed gas chamber, where SF6 gas rapidly cools and extinguishes the arc. The three-position design combines load switching, disconnection, and grounding functions into one compact device, improving operational safety and reducing installation space.<\/p>\n<h2
