1. Preparation: Double-check tools and cables
Tool preparation: Prepare a thin wire or nylon rope (diameter ≤ 1/3 of the inner diameter of the corrugated pipe, e.g., 1.5mm wire for a 5mm pipe), scissors, insulating tape, cable ties or clips (for fixation), and a small amount of silicone lubricant (optional, to reduce friction).
Cable inspection: Confirm that the outer diameter of the cable is ≤70% of the inner diameter of the corrugated pipe (e.g., a 5mm pipe threaded with a cable smaller than 3.5mm). Wrap the ends with insulating tape for 2-3 layers to prevent burrs from scratching the pipe wall; multi-strand wires need to be straightened out in advance and fixed with tape to avoid loose strands.
II. Threading steps: Push, pull, rotate, and easily thread
Opening the pipe orifice: Gently pry open the corrugated pipe along the corrugated pattern at the opening, ensuring that the opening width is ≥ 1.2 times the diameter of the cable (e.g., for a 3mm cable, the opening should be ≥ 3.6mm), and avoid violently tearing the pipe body.
Lead wire insertion: Bend one end of the thin wire into a small hook, insert it through one end of the corrugated pipe until the other end is exposed. If the pipe is curved, apply a small amount of silicone grease lubricant on the inside of the pipe wall to reduce resistance.
Cable fixation: Hook the end of the cable with a small wire hook, or tie the cable tightly to the end of the wire with tape (ensure the tie is secure and does not fall off).
Push-pull threading: One person slowly pulls the wire at one end, while the other person simultaneously pushes the cable gently into the pipe. When encountering a bend, gently rotate the wire while pulling, allowing the cable to slide along the curvature of the pipe wall to avoid getting stuck. If resistance is encountered, withdraw and check whether there are burrs on the cable or pipe wall, and proceed with threading after addressing the issue.
Handling of multiple wires: Multiple wires can be threaded in stages. Start with the main cable, followed by auxiliary wires. Lightly secure the cables with cable ties after each section (about 50cm) is threaded to prevent them from accumulating and tangling inside the tube.
III. Closing and Fixing: Sealing for Dust Prevention and Safety
Tube closure: After all cables have been inserted, gently press the opening of the corrugated tube along its original pattern to ensure a tight closure. If higher protection is required, use clips or ties to reinforce the opening, or wrap it with waterproof tape.
Tube end treatment: Install waterproof connectors or heat-shrinkable sleeves on both ends of the corrugated tube. When connecting equipment, ensure that the connectors are sealed to prevent dust and moisture from entering.
Overall inspection: Gently pull the cable to confirm that it is not loose, check the tube for any damage and ensure that the opening is not leaking, and power on to test whether the cable functions properly.
Caution: Safety first, never be careless
Wear gloves to protect your hands when threading cables to avoid being scratched by cable ends or tools; be sure to cut off the power before operating in high-voltage and high-temperature areas.
Avoid excessively bending the corrugated pipe, and maintain a bending radius of ≥3 times the pipe diameter (e.g., for a 5mm pipe, bend it by more than 15mm) to prevent cracking of the pipe body.
In humid and corrosive environments (such as kitchens and bathrooms), it is necessary to use corrosion-resistant PA66+ glass fiber reinforced corrugated pipes, and to strengthen the sealing of the pipe ends.
Regularly check the condition of cables, and replace them promptly if any signs of aging or damage to the tubes or cables are found, to ensure safe use.
By following the simple steps above, you can complete the manual threading of the open nylon corrugated pipe. It is both practical and safe, suitable for cable protection needs in scenarios such as homes and small devices.
