HJDW6 outdoor low-voltage knife switch
HJDW6 outdoor low-voltage knife switch is a single-phase AC 50HZ low-voltage switchgear, which is used in the power system with rated voltage of 0.5KV to connect or isolate the power supply when there is voltage and no load. The knife switch is operated with insulated hook bar The knife switch is a single-phase structure, and each phase is composed of a word mounting plate, a pillar insulator, a knife switch, a contact, etc. The upper end of the knife switch is provided with a fixed pull ring for opening and closing the insulating hook bar
