Features:

 

The FZW28F-12 circuit breaker adopts a three-phase common box structure, adopts vacuum arc extinction and SF6 insulation, and the outer insulation adopts epoxy resin cast cable outlet structure, reliable insulation performance and strong anti-pollution ability. The isolation knife gate is inside the box, which reduces the corrosion of the isolation switch from the external environment and affects the breaking performance of the upper switch. An advanced miniaturized mechanism is shared between the isolating switch and the circuit breaker. It has a reliable mechanical interlock, and can perform manual opening, closing and electric opening operations. The operation structure is simple and the performance is reliable. The switch has reasonable design, compact overall structure, excellent performance and easy installation. Especially suitable for urban and rural outdoor power grids, and small outdoor transmission and distribution systems. Installing a controller can realize the automation of distribution network, and installing wireless communication can realize remote control.
