GW5-40.5W Outdoor High Voltage AC Disconnector
Usage Environment:
The GW5-40.5 series outdoor high-voltage AC isolating switch is designed for use in outdoor environments with a frequency of 50 Hz. It is utilized for the connection and disconnection of high-voltage lines under voltage conditions and for isolating high-voltage busbars during maintenance. The switch is capable of electrically isolating equipment such as circuit breakers from live high-voltage lines and can handle small capacitive and inductive currents.
Product Features:
1. Versatile Functionality: Enables safe connection and disconnection of high-voltage lines under voltage, as well as isolation of equipment for maintenance.
2. High-Voltage Application: Suitable for use with high-voltage busbars and capable of handling small capacitive and inductive currents.
3. Compliance: Meets technical standards including GB 1985-2014 for High Voltage AC Isolation Switches and Grounding Switches and DL/T 486-2010 for High Voltage AC Isolation Switches and Grounding Switches, ensuring adherence to industry standards.
Precautions:
1. Installation and Operation: Ensure proper installation according to manufacturer guidelines and safety standards. Verify that the switch is correctly connected and functioning before use.
2. Maintenance: Regularly inspect and maintain the switch to ensure reliable operation and prevent performance issues.
3. Environment Considerations: The switch is designed for outdoor use; however, periodic checks for environmental damage or wear are recommended to maintain optimal performance.
4. Handling Capacitive and Inductive Currents: While the switch can handle small capacitive and inductive currents, ensure that its use is within the specified limits to avoid operational issues.
