Product Description

Indoor AC high voltage sulfur hexafluoride load switch is an indoor device with three-phase AC 50Hz and rated voltage of 12kV. It is suitable for ring network or terminal power station and industrial electrical equipment. It is used for combining transformer, no-load current and cable charging current.
FLN36-12 sulfur hexaoxide load switch is a multi-functional medium voltage switchgear integrating load switch, grounding switch and isolating switch. It is filled with 0.045MPA SF6 gas uses a small number of components to achieve the above three functions, thus ensuring the quality and reliability of the product, with excellent insulation box switch function, and can ensure the safe operation of the equipment for 20 years under normal conditions. The circuit is performed by a manual or electric operating mechanism independent of the switch, and the opening and closing of the grounding circuit is performed. The opening and closing speed of the switch is determined by the spring, which has nothing to do with the manual speed. After installing an automatic instrument, remote sensing and remote control can be realized.

Product features and scope of use

1. FLN36-12 (24) type high voltage SF6 load switch. The switch shell is formed by vacuum casting of reinforced epoxy resin, and the shell is filled with 1.45barSF6 gas as insulation and arc extinguishing medium.
2. The switch is a double-break, rotating moving contact, with three positions of closing, breaking and grounding or two positions of closing, breaking and (unlocking).
3. An explosion-proof pressure relief channel is designed at the rear of the switch housing to ensure that operators are not harmed by high-temperature and high-pressure explosive gas in extreme conditions.
4. FLN36-12/T630-20 type SF6 load switch, equipped with K type compression type single spring operating mechanism. Commonly used in switch cabinets for incoming and outgoing lines.
5. FLRN36-12D/T125-50 type SF6 load switch-fuse combination, equipped with A type compression type double spring operating mechanism. It is often used in feeder and outlet cabinets such as transformers.
6. The lower part of the switch body has a built-in capacitive sensor.
7. The switch is small in size, the busbars are arranged vertically, and the assembly with the cabinet is simple and convenient. Flexible and reliable operation. Safe and stable operation, maintenance-free during life.
8. Optional electric operation.
9. A barometer and air pressure contacts can be installed.
