Ⅴ. Installation and Maintenance

Proper installation:
When installing rail clips, strictly follow the installation instructions to ensure that the connection between the spring clip and the rail and other components is correct.
Avoid causing damage to the insulating layer during the installation process, such as scratches and collisions.
Ensure that the installation position of the insulating components is accurate to play its due insulating role.

Regular inspection and maintenance:
Regularly inspect the insulating performance of rail clips and deal with problems in a timely manner. Professional insulation testing equipment can be used for detection to ensure that the insulating performance meets the requirements.
Replace damaged insulating components in a timely manner to maintain the good insulating state of rail clips.
Clean rail clips and surrounding components to prevent dust, dirt, moisture, etc. from affecting the insulating performance.

Through the above methods, the insulation of rail clips can be effectively guaranteed and the safety and reliability of the railway system can be improved.
