Sakelar Pemutus Beban SF6 Dalam Ruangan FLN36

The FLN36 series indoor SF6 load break switch is a medium voltage gas insulated switch disconnector designed for 12kV, 24kV, and 36kV power distribution systems. 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.

Spesifikasi Teknis

Working Principle

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.
