Layout Recommendations For High-voltage Disconnect Switches

When positioned on the side phase, the mechanical transmission path of switch high voltage electrical isolator is more direct. Side-phase installation shortens the connecting rod length, thus reducing mechanism delay. Simultaneously, the mechanism's position close to the phase rod axis concentrates the stress point of the power chain, improving structural stability.

With a side-phase arrangement, the maintenance access can be designed as a laterally open structure, facilitating quick access for on-site maintenance personnel to switch isolator high voltage. There's no need to traverse the inter-phase structure, making the operating area clearer. The side-phase layout also facilitates the unified arrangement of control boxes, cable outlets, and operating devices within the overall switch structure, simplifying cable laying and wiring.
