The FLN36-12 12KV indoor SF6 load break switch is a specific model of load break switch that is designed for use in indoor medium voltage power distribution systems. It is commonly used for load breaking and isolation applications in power distribution networks with a voltage rating of up to 12kV. The FLN36-12 indoor SF6 load break switch uses SF6 gas as a medium to interrupt the flow of current. It consists of a compact enclosure that houses the switch contacts, operating mechanism, and SF6 gas. The switch contacts are designed to withstand high electrical stresses and are separated by a small gap that is filled with SF6 gas. When the switch is closed, the SF6 gas provides excellent insulation and allows current to flow through the switch. When the switch is opened, the SF6 gas is released, creating a quenching effect that extinguishes the electrical arc and interrupts the flow of current. The FLN36-12 indoor SF6 load break switch is designed to be reliable and require minimal maintenance. It has a high breaking capacity and can handle high electrical stresses without damage. It also features a visible open/close position indicator, a locking mechanism to prevent accidental operation, and a variety of accessories for remote operation and monitoring. Overall, the FLN36-12 indoor SF6 load break switch is a reliable and efficient component of medium voltage power distribution systems, and is widely used in a variety of industrial and commercial applications.
