The FLN36-12 indoor high‑voltage AC load switch is a medium‑voltage switchgear independently developed by our company. It adopts advanced international technologies and complies with relevant standards of China’s power system.
All performance indicators meet IEC 60420, IEC 60694, IEC 62129 and national standards including GB3804‑2004 《3.6kV～40.5kV High‑voltage AC Load Switches》, GB1985‑2004 《High‑voltage AC Disconnectors and Earthing Switches》 and GB/T11022‑1999 《Common Specifications for High‑voltage Switchgear and Controlgear》. It serves as the core switching component for ring main units.
This load switch integrates closing, opening and earthing functions into one unit. It is fully sealed inside a reinforced epoxy resin shell filled with SF₆ gas at 0.05MPa. The three functions are realized with minimized parts, guaranteeing stable quality and high reliability. It is maintenance‑free and can operate safely for more than 20 years under normal service conditions.
