FKW17-12/630 Outdoor AC High Voltage Load SwitchDetailed product description：

FKW17-12/630 outdoor AC high-voltage load switch is suitable for three-phase AC 50Hz, rated voltage 10kV outdoor distribution systems. It is used for breaking and closing load currents, as well as for breaking and closing no-load lines and no-load transformer currents.
This load switch is equipped with a dedicated manual electric dual-purpose operating mechanism, as well as connecting rods, couplings, universal ball hinges, supports, and other installation accessories.
Product Features

FKW17-12/630 outdoor load switch, consisting of isolation knife switch and arc extinguishing chamber; The isolation knife switch structure adopts a horizontal rotation method, mainly composed of components such as chassis, bracket, insulator, isolation knife plate, etc; The arc extinguishing chamber is made of insulation materials with excellent electrical performance, arc resistance, high temperature resistance, and high strength. It is equipped with a fast mechanism to ensure that the current interruption is not affected by the operating speed, and the performance is stable.

The switch is installed on the outdoor column and can be installed horizontally, vertically, and in various other ways. It uses universal ball hinges and couplings to connect the switch with the manual operating mechanism. The operating mechanism can be locked in the open or closed position. There is a clear isolation fracture after the switch is opened.
