Description
The F L（R）N36-12 model SF6 high voltage load switch is a 10KV high-voltage switchgear developed in accordance with power system requirements, tts performance meet or exceed the relevant national standards, has been widely used in 10KV power distribution system. Often used as main switch of inlet and outlet line for RMU, outdoor cable distribution box, outdoor switching station and other high voltage equipment. Carried out the main loop and ground loop switching and breaking by an independent manual or electric actuator, the switching speed is determined by spring, nothing to do with manual speed, after the installation of automated instrumentation, can achieve remote sensing and remote control.

Features
1. FL（R）N36-12 model SF6 high voltage load switch. The switch housing is made of reinforced epoxy resin by vacuum casting molding, filled in the housing with SF6 gas as insulating and arc extinguishing medium, the pressure is 0.045Mpa.
2. The switch comes with double fracture rotary moving contact, has three positions of closing, breaking and grounding, or two positions of closing and breaking.
3. The back side of switch housing is designed with explosion relief channel, that can protect the operator against high temperature and high pressure gas explosion damage under extreme conditions.
4. FLN36-12/T630-20 model SF6 load switch is equipped with a K-type single compression spring operating mechanism. Commonly used in the inlet and outlet switchgear.
5. FLRN36-12D/T125-50 model SF6 load switch - fuse combination, equipped with A-type double compression spring operating mechanism. Commonly used in transformers and other power feeding outlet cabinet.
6. Built-in capacitive sensor in the lower part of switch body.
7. Small size switch, busbar longitudinally arranged. Flexible and reliable operation, secure and stable, maintenance-free during the lifetime.
8. The electric operation function is optional.
9. The pressure gauge and pressure contact point can be installed.
