ABG2 SERIES OUTDOOR HIGH VOLTAGE ISOLATING SWITCH
ABG2 series outdoor high voltage isolating switch is designed for single-phase use in three-phase electrical systems, offering a straightforward, economical, and user-friendly structure.
The ABG2 isolating switch features a single-pole, vertical open-type structure where the single-phase isolating switch pillar insulators are mounted on their respective bases. It consists primarily of a base, pillar insulators, main conducting circuit section, and self-locking device. Using a knife-type mechanism, it achieves circuit interruption and closure. Each isolation switch consists of two conductive blades with compression springs on either side, allowing adjustment of spring height to achieve the required contact pressure for the switch blades. The opening and closing of the switch is operated using an insulated hook rod mechanism, and the isolation switch includes a self-locking device for safety during operation.
For closing the ABG2 isolation switch, the insulated hook rod presses against the locking hook of the isolating switch, causing the shaft to rotate. This rotation moves the connected conductive plate to the closed position. At this point, the self-locking device secures the isolating switch in the closed position.
This ABG2 isolating switch can be installed on pillars, walls, ceilings, crossbeams, or metal frames. It can also be mounted vertically or at an angle, but the installation position should ensure that the knife switch tends downwards when opened.
