Product details
summary:
The GW4-12 (15,40.5,72.5) series outdoor high-voltage AC isolation switch is suitable for installation in outdoor AC 50Hz power systems with rated voltages of 12kV and 40.5kV respectively. It is used as a switching circuit for power lines when there is voltage and no load. The product meets the requirements of GB1985 and other relevant standards.
Structural features:
The isolation switch consists of a base, insulating support, conductive parts, and operating mechanism. There are two pillars each, and each pillar is equipped with a conductive blade at the upper end. The contact points of the blade contacts on both sides are located in the middle of the two pillars. The lower ends of the pillars are equipped with bearing sleeves, which, under the drive of the operating mechanism, can rotate the blade horizontally by 90 ° to achieve the requirements of opening and closing the switch.
The isolation switch is a single type, or it can be connected into three types that can be linked through a connecting rod. Equipped with CS11 or CS8-6D manual mechanism for operation. CS17 is used for isolating switches with dual grounding devices (which can be used for power distribution mechanisms as needed).
This isolation switch has a reasonable structure and flexible operation; Can be used individually or in triplicate, easy to install; The contact blade has a large opening distance, ensuring safe and reliable insulation. According to user needs, it can be ungrounded or equipped with single-sided grounding or double grounding.
