ADSS optical cables can be stripped using manual, semi-automated, or fully automated mechanical methods, with careful attention to layer sequence and fiber protection.

Manual Stripping

Manual stripping is the most common method for ADSS cable maintenance and splicing. The process involves:

1. Fixing the cable: Secure the ADSS cable in a splice or connection box to prevent movement during stripping .
2. Outer sheath removal: Strip the outer jacket horizontally first, then vertically, typically about 1 meter in length. Care must be taken not to damage the inner layers .
3. Inner layers: Remove the inner cushion layer and filling materials, leaving the aramid yarn exposed. The yarn is often braided and fastened to the splice box for reinforcement .
4. Loose tube and fiber preparation: Leave a portion of the loose tube (e.g., 20 cm), cut with special wire strippers, and carefully pull out the fiber cores in parallel .
5. Fiber coating removal: Use precision fiber strippers to remove the primary and secondary buffer coatings without nicking the glass fiber. Clean the bare fiber with alcohol before cleaving . Precautions: Avoid squeezing or stressing the loose tube, and ensure the stripping knife depth is controlled to prevent fiber damage. Each layer must be stripped progressively, not all at once .

Semi-Automated and Automated Stripping

To improve efficiency and consistency, mechanical stripping devices have been developed:

• Mechanical execution: Devices clamp the fiber and remove coatings using controlled mechanical blades .
• Control systems: Automated systems regulate stripping speed, blade pressure, and alignment to minimize fiber damage .
• Waste collection: Stripped materials are collected to maintain a clean workspace . These devices are modular and can handle multiple layers simultaneously, reducing operator skill requirements and improving repeatability .

Tools Used

• Hand-held wire strippers: For outer jackets and aramid yarn.
• Precision fiber strippers: For primary and secondary buffer coatings.
• Heated stripping tools: Optional for softening buffer tubes to ease removal.
• Automated mechanical strippers: For high-volume or repetitive operations .

Best Practices

• Maintain sharp blades to ensure clean cuts.
• Strip layers progressively to avoid damaging underlying fibers.
• Clean fibers thoroughly after stripping to remove debris or coating residues.
• Follow safety protocols when working on overhead or energized lines . By combining careful manual techniques with automated tools where appropriate, ADSS optical cables can be stripped efficiently while minimizing the risk of fiber damage.
