How to install Cable Markers on cables after post-termination?

1. Site Preparation

Clean the cable surface of oil, dust, and residual insulation material, ensuring the marking surface is clean and dry.

Confirm the cable number, specifications, and laying route according to the design documents.

2.Select the appropriate marking method

Self-adhesive labels: Suitable for smooth surfaces, using weather-resistant adhesive, can be directly affixed to the cable sheath.

Clamp-type markings: Use stainless steel or aluminum alloy clamps with metal labels, suitable for large-diameter or multiple cable bundles.

Poles/Warning signs: Install poles at cable entry/exit points (such as pipe openings, equipment rooms), with a spacing not exceeding 100m.

3. Marking Location Layout

Critical Nodes: Cable Markers must be installed at cable entry/exit points, bends, branches, intersections, terminal junction boxes, etc.

Intermittent Layout: On long-distance cables, install self-adhesive labels every 3-5m for quick on-site identification.

Labeling Direction: Label text should be aligned along the cable's direction, using fade-resistant ink or laser engraving to ensure long-term legibility.

4. Fixing and Reinforcement

For self-adhesive labels, use a pressing tool to ensure proper adhesion; for clamp-type labels, use bolts or quick-release clips to secure them, preventing them from falling off due to vibration or tension.

In high-temperature or humid environments, waterproof tape or heat-shrink tubing can be added to the back of the label for secondary protection.

5. Recording and Delivery

After marking is completed, take photos on-site for archiving, and list the marking location, number, and marking type for each cable in the delivery documents.

Synchronize the marking information to the project management system for easy later maintenance and asset traceability.
