Isolation Switch Manufacturer

An isolating switch is a switch device primarily used for "isolating power, switch operation, and connecting or disconnecting low current circuits" without arc-quenching capabilities. When in the open position, the switch contacts have an insulating distance and a clear break indication that meet regulatory requirements; in the closed position, it can carry the current under normal circuit conditions and the current under abnormal conditions (such as a short circuit) within a specified time. Generally used as a high-voltage isolating switch, i.e., isolating switches with a rated voltage of 1kV or more, it has a relatively simple working principle and structure. However, due to its high volume of use and stringent reliability requirements, it has a significant impact on the design, establishment, and safe operation of substation and power plant facilities. The main feature of an isolating switch is its lack of arc-quenching capability, allowing for circuit opening and closing only under no-load current conditions. The entry describes the functions, features, types, applications, anti-misoperation improvements, maintenance, and common issues of isolating switches.
