3. What are the different types of cable cutters?

   • Answer: Types include hand-held cutters (ratcheting, bolt cutters, diagonal cutters), hydraulic cutters, and power-operated cutters (electric, pneumatic).

4. What are the different types of swagers?

   • Answer: Types include hand-held swagers (using crimping dies), hydraulic swagers, and pneumatic swagers. They can be further categorized by the type of connector they accommodate.

5. Explain the importance of proper cable cutting techniques.

   • Answer: Proper techniques ensure a clean cut, preventing damage to the cable conductors, which can compromise signal integrity or electrical safety.

6. What are the safety precautions when using cable cutters?

   • Answer: Wear safety glasses, gloves, and appropriate clothing. Ensure the cable is properly supported and secured before cutting. Never cut energized cables.

7. How do you choose the right cable cutter for a specific job?

   • Answer: Consider the cable type and diameter, the required cutting capacity, and whether hand-held or power operation is preferred.

8. What are the safety precautions when using a swager?

   • Answer: Wear safety glasses. Ensure the connector and cable are properly aligned in the swager before crimping. Use the correct crimping die for the connector type.

9. How do you ensure a proper crimp on a cable connector?

   • Answer: Use the correct crimping die and apply the correct amount of pressure. Inspect the crimp visually and sometimes with a pull test to ensure a secure connection.

15. What is the difference between a hydraulic and a pneumatic swager?

    • Answer: Hydraulic swagers use hydraulic pressure, while pneumatic swagers use compressed air. Hydraulic swagers generally offer more precise control and higher crimping force.

16. How do you identify the correct crimping die for a specific connector?

    • Answer: Consult the connector manufacturer's specifications or the swager's instruction manual. Dies are often color-coded or marked for specific connector types and sizes.

17. What is the importance of using the correct crimping force?

    • Answer: Insufficient force results in a loose crimp; excessive force can damage the connector or cable.

18. How can you tell if a crimp is properly done?

    • Answer: Visually inspect the crimp for a full, even deformation of the connector's contact area onto the cable. A pull test (within safe limits) can further assess its strength.

19. What are some common cable types that require special cutting or crimping techniques?

    • Answer: Fiber optic cables require specialized tools and techniques to avoid damage to the fibers. Coaxial cables need care to avoid damaging the inner conductor.

20. What is the purpose of a stripping tool in cable preparation?

    • Answer: A stripping tool removes the outer jacket and insulation from a cable without damaging the conductors. It's a crucial step before terminating or crimping a connector.

21. Explain the process of preparing a cable for crimping a connector.

    • Answer: This involves measuring the required cable length, stripping the outer jacket and insulation, tinning the conductors (if necessary), and inserting the conductors into the connector's terminals.

22. What are the potential consequences of an improperly crimped connector?

    • Answer: Poor signal quality, intermittent connections, electrical hazards, and potential connector failure.

23. How can you troubleshoot a faulty cable connection?

    • Answer: Inspect the crimp for damage, check the continuity of the conductors, and verify the correct installation of the connector.

24. What are some of the factors that can affect the lifespan of cable cutters and swagers?

    • Answer: Regular use, proper maintenance, the quality of materials used in manufacturing, and the types of cables cut or crimped.
