Materials needed for the installation process
Placing the RUBNS-OLC silicone cover onto the protected object, Apply RTV glue into the concave channel of the RUBNS-OLC and secure the cover tightly
Utilize a cable tie to secure the RUBNS-OLC in place.
Apply RTV glue to join the two ends of the RUBNS-OLC and coat the surface of the connection. Take a 50~90mm section of RUBNS-OLC, roll and wrap it, and then use self-fusing tape for additional reinforcement.
Prior to installation, inspect the concave channel to ensure there is no foreign matter
When applying the RTV glue, it is crucial to distribute it evenly to prevent any cracking
After securing the RUBNS-OLC in place, utilize a cable tie to fix it, thereby preventing any potential cracking
After finishing the above steps, make sure to position the RUBNS-OLC slot underneath the cable to prevent rainwater from entering and influence the insulation properties
