cable lacer Interview Questions and Answers

1. What is a cable lacer?

   • Answer: A cable lacer is a specialized tool used to cut and strip the outer jacket of cables without damaging the internal conductors. It features a rotating blade or cutting wheel that scores the jacket, allowing for easy removal.

2. What are the different types of cable lacer?

   • Answer: There are manual cable lacerators (hand-held), and electric/pneumatic lacerators (powered). They also vary by blade type and size, to accommodate different cable diameters.

3. How do you select the right cable lacer for a job?

   • Answer: Consider the cable diameter, material (e.g., PVC, polyethylene), required cutting speed, and whether you need a portable or stationary tool. The manufacturer's specifications will guide you.

4. What safety precautions should be taken when using a cable lacer?

   • Answer: Always wear appropriate safety glasses, gloves, and potentially hearing protection (for powered models). Ensure the cable is securely held and avoid loose clothing near moving parts. Disconnect power before maintenance.

5. How do you maintain a cable lacer?

   • Answer: Regularly clean the blade and cutting mechanism, lubricate moving parts as recommended by the manufacturer, and inspect for damage before each use. Replace worn blades promptly.

6. What are the common problems encountered when using a cable lacer?

   • Answer: Dull blades, improper cable clamping, incorrect adjustment of cutting depth, and potential damage to the inner conductors due to excessive force are common issues.

7. How do you troubleshoot a jammed cable lacer?

   • Answer: Disconnect power (if applicable), carefully remove the jammed cable, clean any debris from the cutting mechanism, and inspect for any obstructions or damage.

8. What is the difference between a cable lacer and a cable stripper?

   • Answer: A cable lacer scores the outer jacket to facilitate removal, while a cable stripper typically uses a sharp blade to directly cut through the jacket. Laceration is generally preferred for larger cables and prevents damage to inner conductors.

9. What are the advantages of using a cable lacer?

   • Answer: Faster and cleaner cutting, especially for larger cables, reduced risk of damaging inner conductors, and improved efficiency compared to manual methods.

10. What are the disadvantages of using a cable lacer?

    • Answer: Higher initial cost compared to manual tools, potential for injury if used improperly, and the need for regular maintenance.

11. Describe the process of lacerating a coaxial cable.

    • Answer: Carefully clamp the coaxial cable, ensuring the outer jacket is properly engaged. Adjust the cutting depth to score only the outer jacket. Rotate the lacer to score the jacket completely around the cable. Gently pull the scored jacket away, taking care not to damage the braided shielding or inner conductor.

12. How do you dispose of a damaged cable lacer blade?

    • Answer: Dispose of sharp blades according to local regulations, usually in designated sharps containers.
