1. Product Description
        GW5-40.5 Series outdoor high-voltage isolation switch is suitable for AC rated voltage 40.5KV, three-phase AC 50Hz outdoor isolating devices. With advanced design, reliable technical performance, simple structure, easy installation, etc., for high voltage lines in the no-load situation grafting. As well as being high voltage bus maintenance, circuit breakers and other electrical equipment and charged high voltage lines for electrical isolation. It can also be used to open, close small capacitance current or inductor current.
2. Structure Introduction
        GW5 Series outdoor high-voltage isolation switch is a double column horizontal rotary structure, the switch pole from the base, current loop and each composed of two post insulators. Within the base has a pair of bevel gears, along the respective axes to cook, the next move to adjust the status of two meshing gears; two post insulator V-shaped angle of 50 degrees; current loop at the upper end of the post insulator.
