Structure and Features：
Structural Design: Employs a three-phase independent vacuum interrupter chamber + silicone rubber insulating bushing (integrated solid-sealed pole design, moisture-proof and pollution-resistant), coupled with a spring-operated mechanism; the housing is mostly stainless steel/aluminum alloy, supporting manual, electric, and remote control.
Core Advantages:
Reliable Insulation: Silicone rubber bushing + solid-sealed pole, resistant to high pollution and high humidity environments;
Flexible Functions: Can be integrated with disconnect switches, current/voltage transformers, and equipped with intelligent controllers to achieve reclosing, remote control, and fault isolation;
Easy Maintenance: Mechanical life ≥ 10,000 cycles, long maintenance-free period.
Typical Applications：
Conventional Scenarios: 10kV line sectionalizing switches, distribution transformer incoming line switches;
Intelligent Scenarios: As a user boundary switch (identifies and isolates user-side faults), or used in conjunction with distribution automation systems to achieve line self-healing.
