FLN36-12/24 Indoor AC High Voltage SF6 Load Break Switch Break Switch
The product has "joint-division-ground" three-position arc chamber, with reliable interlocking, high dielectric strength of fracture, design of large creepage path, and its leading-out terminal is protected by a voltage-sharing protection cover. For the cable head installable load break switch, its outgoing end is equipped with touch-type cable connector, the outgoing line is installed with high-voltage cable, equipped in cable branch (distribution) box. The switch has special dynamic seal and fixed seal design, which is reliable, and it is equipped with a voltmeter in a clear position for monitoring in operation to ensure safe operation, which is a new generation of high voltage switchgear for urban power grid.
This product is suitable for three-phase AC 10KV,20KV,50Hz power system, for cut-off, turning off load current, fault current, control, protective circuit and distribution transformer in industrial and mining enterprises, high-rise buildings, residential quarters and prefabricated substation.
