Integrated Three-Phase Enclosed Structure:The switch adopts a compact three-phase integrated design, with the main circuit and operating mechanism housed within a single sealed enclosure, improving reliability and reducing maintenance needs.

SF₆ Gas Insulation with Sealed Tank Design:The internal chamber is filled with SF₆ gas and uses a fully sealed tank structure, ensuring excellent insulation performance, arc-extinguishing capability, and long-term operational stability.

External Silicone Rubber Insulators:High-performance silicone rubber bushings are used for external insulation, offering strong resistance to pollution, UV exposure, and harsh outdoor environmental conditions.

Modular Operating Mechanism with Visible Isolation Function:The switch features a mechanical linkage system that enables clear open/close status indication and supports coordinated operation with isolation and grounding functions, enhancing safety and operational clarity.
