FLN36 SF6 Load Switch & Fuse Combination
Indoor SF6 load switch family (FLN36 / FLRN36, 12 & 24 kV) with Close-Open-Earth three-position interrupter, visible pressure gauge, safety diaphragm and optional touch-safe cable heads — to GB 3804 / GB 16926 / IEC 60265 / 60420.
- Switch and combination share the same epoxy-injected upper/lower housings forming the gas cavity; the common r
- Front panel carries the SF6 gauge and a position indicator directly coupled to the contact shaft; a rear safet
- Reliable mechanical interlocks: load switch ↔ earthing switch, earthing switch ↔ front door (for cabinet build
- TII manual spring mechanism: upper hole earths, lower hole switches; closing charges the opening spring, relea
- TII electric version adds motor charging and shunt-trip coil — manual and electric fully independent; AC220 /
A cleaner, more reliable approach to MV switching
The HP-ELS series replaces SF₆ with environmentally friendly insulating media while keeping the proven safety and performance utilities expect from gas-insulated switchgear.
Product Overview
The FLN36-12(24)D and FLRN36-12(24)D indoor AC high-voltage SF₆ load switches, load-switch-fuse combination units and cable-head-mountable load switches are independently developed by absorbing advanced foreign technology to suit domestic operation. Passing full type tests, they comply with GB3804 (3–63 kV AC HV load switches), GB16926, IEC60265 and IEC60420. With a three-position “Close–Open–Earth” arc chamber, reliable interlocking, high break-point insulation and large creepage design, they suit three-phase AC 10 kV and 20 kV, 50 Hz systems in industrial/mining sites, high-rises, residential communities and prefabricated substations — for switching load and fault currents and protecting lines and distribution transformers.
