Cable Sheathing Removal Techniques

2.1 Introduction to Cable Jacketing Removal

What is Cable Jacketing Removal?

Stripping is the process of removing the insulating sheath that surrounds the metallic conductors of a cable. This process is essential to prepare wires for connection and soldering in electronics and robotics projects.

Importance of Cable Sheathing Removal

• Connection PreparationWithout removing the sheathing, the metallic conductors of the cable cannot make contact with other components or cables.
• Welding QualityProper stripping of the coating ensures that the solder adheres properly to the conductor, forming a solid and reliable connection.
• Security: Removing the coating in the correct way avoids damaging the metallic conductors, which could cause short circuits or failures in the circuit.

2.2 Types of Cables and How to Identify Them

Solid Wire Cables

• DescriptionComposed of a single metallic conductor surrounded by an insulating layer.
• Common UsesConnections on protoboards and in projects that do not require flexibility.
• AdvantagesEasier to insert into small holes and fittings due to its rigidity.

Stranded Wire Cables

• DescriptionComposed of multiple fine wires of metallic conductor stranded together and surrounded by an insulating layer.
• Common UsesConnections that require flexibility, such as in mobile robots or moving devices.
• AdvantagesGreater flexibility and resistance to breakage due to repeated bending.

How to Identify Cable Types

• Visually: Look at the end of the cable. Solid wire cables have a single visible wire, while stranded cables have multiple strands.
• TouchSolid wire cables are stiffer and less flexible when bent, while stranded cables are softer and more flexible.

2.3 Practical Demonstration of Coating Removal

Necessary Tools

• Cable StripperSpecific tool to remove the cable sheathing without damaging the internal conductors.
• Cable CutterTo cut the cable to the desired length before removing the sheathing.

Steps to Remove the Cable Sheathing

1. Measuring and MarkingDecide how much coating you need to remove and mark the wire if necessary.
2. Selecting the Right SlotOn the cable stripper, select the slot that corresponds to the diameter of the cable you are using.
3. Insert CablePlace the cable in the groove of the cable stripper, making sure to align the mark with the stripper blade.
4. Apply Pressure and RotateGently squeeze the stripper and twist the cable or stripper to cut the sheathing without damaging the inner metallic conductor.
5. Remove the CoatingOnce the sheathing is cut, pull it off to remove it and expose the metal conductor.

Practical Advice

• Prevents DamageDo not squeeze the wire stripper too hard, as you may damage the inner conductor.
• ConsistencyPractical to obtain consistent and clean cuts in the cable sheathing.
• SecurityMake sure that the cable is disconnected from any power source before removing the liner.
