Structure and Features：
Structural Design: Utilizes a three-phase common-enclosure stainless steel enclosure, integrating a vacuum interrupter and spring-operated mechanism (supporting manual/electric operation); external insulation uses silicone rubber tubing, resistant to pollution and UV radiation, suitable for complex outdoor environments.
Core Advantages:
Reliable Arc Extinguishing: Vacuum interrupter + longitudinal magnetic field design ensures stable breaking capacity and long electrical life;
Strong Functional Expandability: Can be equipped with disconnect switches, current/voltage transformers, prepaid modules, and intelligent controllers (enabling reclosing and remote control);
Good Environmental Adaptability: Withstands temperatures from -40℃ to +40℃, altitudes ≤2500m, wind pressure resistance, and corrosion resistance.
Typical Applications：
Basic Scenarios: Line sectionalizing/interconnecting switches, transformer protection switches;
Upgraded Scenarios: With the addition of a controller, it functions as an intelligent recloser, automatically eliminating transient faults and isolating permanent faults; or as a prepaid switch, enabling "buy now, use later" electricity.
