The purpose of outdoor high-voltage composite isolation switches is similar to traditional outdoor high-voltage isolation switches, but due to their use of composite insulation structures (such as silicone rubber jackets), they are more suitable for harsh environments in terms of performance.

Its main uses can be summarized as:

1. Provide reliable electrical isolation during equipment maintenance to reliably disconnect the parts to be repaired from the live system, forming a clear air insulation gap to ensure the safety of personnel and equipment.  

2. Switching operation and operation mode are used in substations, switch stations, and distribution stations to switch between lines and busbars, achieving the adjustment of system operation mode.  

The standard configuration of outdoor high-voltage distribution systems is widely used in outdoor distribution equipment, box transformers, switch stations, and other scenarios with voltage levels such as 10kV and 35kV.  

4. Insulation protection composite insulation materials that are suitable for harsh environments have excellent resistance to pollution, moisture, and corrosion, and are suitable for coastal areas, chemical zones, heavily polluted areas, high-altitude areas, etc.  

5. Compared to traditional ceramic isolation switches, composite isolation switches are lighter in weight, less prone to breakage, stronger in resistance to pollution and flashover, and easier to maintain.  

6. Improve the reliability of system operation with a compact structure, strong weather resistance, and stable mechanical performance. It can maintain good insulation and operational performance under conditions such as strong winds, ice and snow, and pollution
