GW13 series is an outdoor high-voltage AC isolation switch designed specifically for AC 50Hz power systems. It is mainly used for opening and closing circuits under no-load conditions to achieve electrical isolation or transformer neutral point connection operation
Modular layout: Modular combination of brackets, bases, post insulators, and conductive parts, supporting inclined installation (such as 25 ° brackets).
The GW13 series isolation switch, with its high reliability, low maintenance requirements, and flexible adaptability, has become a key equipment for safe isolation in high-voltage power systems. The selection should be comprehensively evaluated based on voltage level, current capacity, and environmental conditions.
