PRODUCTS DETAILS

FLN36-12 SF6 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 in a fully sealed epoxy resin enclosure with reinforced structure, and uses a small amount of components to achieve the above three functions. Therefore, it ensures the quality and reliability of the product, and has excellent insulation box switching function, Under normal conditions, the equipment can operate safely for 20 years.


The circuit is operated by a manual or electric operating mechanism independent of the switch. The opening and closing speed of the grounding circuit is determined by the spring, independent of the manual speed. Remote sensing and remote control can be realized after the installation of automatic instruments.
