FKW-36 Outdoor Line Disconnector 36kV 630A – Load Break Switch Gas Arc Extinguishing 1000m Altitude
Advanced FKW-36 Outdoor Line Disconnector Series: Premium FKW-36/630 outdoor AC high voltage isolate switch designed for rated voltage 40.5kV and below, rated frequency 50Hz outdoor three-phase AC power distribution systems, featuring gas arc theory with disconnect blade, arc extinguishing chamber and operating mechanism, delivering 630A rated current for opening/closing distribution lines with load, breaking load circuits and no-load transformers, incorporating parallel fracture design where interrupter fracture and isolate fracture close simultaneously, ensuring arc-quenching fracture handles arcing without main current-carrying tasks while isolated blade bears load flow and short-circuit making without arcing participation.
Horizontal and Vertical Mounting Ready: FKW-36 incorporates manual rod or electric actuator operation with lockable opening/closing positions, visible fracture after disconnection for isolation protection, pole-mounted outdoor installation adaptable to severe contamination, horizontal/vertical mounting convenience, simple structure, less maintenance (100 breaking operations without repair), spring-loaded contact pressure, integral drive connecting rod for three-pole synchronous operation, operating at -25°C to +40°C, altitudes ≤1000m, providing reliable gas arc extinguishing outdoor line disconnector solution.
