Structure and Features：
Structural Design: Employs a three-phase common-enclosure sealed housing (mostly aluminum alloy/stainless steel), with an internal vacuum interrupter and spring-operated mechanism; external insulation is a silicone rubber sleeve, paired with an isolating switch (integrated in some models), supporting manual/electric/remote operation.
Core Advantages:
Sealed and Moisture-proof: The housing uses SF₆ gas or air insulation + sealed design, suitable for outdoor humid and polluted environments;
Automation Adaptability: Can be equipped with an intelligent controller to achieve reclosing, fault isolation, and remote control;
Flexible Operation: Supports local manual opening and closing, and electric operation; some models have manual energy storage function.
Typical Applications：
Basic Scenarios: Section switches and user boundary switches for 10kV distribution network lines;
Intelligent Scenarios: As a distribution network automation terminal device, it works with distribution automation systems to achieve fault self-healing and remote operation and maintenance.
