Anqiang Power's 12KV outdoor disconnecting switch features a single-break, vertically opening structure. The single-pole disconnect switch's support insulators are mounted on their respective base frames and mainly consist of a base, support insulators, main conductive circuit components, and a self-locking device. It uses a knife-switch structure for opening and closing the circuit. The anti-pollution type outdoor high-voltage disconnect switch meets the requirements of users in severely polluted areas and effectively solves the problem of flashover during the operation of the disconnect switch.

This 12KV outdoor disconnecting switch is operated using an insulating hook stick during opening and closing. The insulating hook stick engages the locking hook of the disconnect switch. Pulling the locking hook in the opening direction releases the self-locking mechanism, causing the connected conductive plate to rotate and perform the opening action. During closing, the insulating hook stick pushes against the locking hook of the disconnect switch, rotating the shaft and causing the connected conductive plate to rotate to the closed position. At this point, the self-locking mechanism locks the disconnect switch in the closed position.
