Cable Manufacturing and Cable Processing Technologies

In the modern world, cables play a vital role in many fields, such as energy transmission, data communication, and industrial automation. They have a wide range of applications, from automotive to defense industry, medical devices to the aviation sector. With the advancement of technology, cables have become more durable, efficient, and reliable, while manufacturing processes are accelerated with automation systems. Cable production is a process consisting of various stages to obtain products with high electrical and mechanical performance. The materials used in this process, cable manufacturing techniques, and processing technologies vary depending on the application of the cable. In this article, we will discuss the cable production and processing processes in detail. If you are interested in cable, conductor production, and processing processes, we invite you to Wire Eurasia, the most prestigious event in the wire, cable, and conductor industry.

Cable Manufacturing Stages

Cable manufacturing processes consist of various stages to achieve products with high electrical and mechanical performance. The materials used in this process, manufacturing techniques, and processing technologies vary depending on the cable's application area. The cable manufacturing steps can be summarized as follows:

  • Wire Drawing: The first step in cable manufacturing is wire drawing, where copper or aluminum wires, which are the basic conductors of the cable, are passed through special rollers to thin them. This step is done to reduce the wire's diameter and increase its flexibility.
  • Annealing: The drawn wires, which become hardened, are softened through a controlled heating process. This increases the conductivity of the wires and optimizes their mechanical strength.
  • Conductor Formation: The thin wires are gathered into the desired number and the conductor formation step is applied. These conductors can be either single or multi-strand. Multi-strand conductors provide greater flexibility to the cable.
  • Twisting: Multiple wires are twisted together to create multi-strand conductors, enhancing their conductivity, mechanical durability, and flexibility.
  • Insulation Coating: To provide electrical insulation, the conductor is coated with materials such as PVC, XLPE, Teflon, or rubber.
  • Inner Sheath Coating (Filling): A filling material may be used to cover the gaps around the twisted conductors and give the cable a round shape.
  • Outer Sheath Coating: To protect the cable from external factors, an outer sheath coating is applied with materials such as PVC, polyethylene, or rubber. The outer sheath material should be selected based on the cable's application and the conditions it will be exposed to.
  • Testing and Quality Control: At the end of the cable manufacturing process, the cables must undergo electrical, mechanical, and environmental tests. Tests such as high voltage, insulation resistance, and fire resistance are applied to confirm compliance with standards.

Cable Processing Stages

Cable processing stages involve the processes applied to raw cables to make them suitable for their final use. Especially in fields like automotive, electrical-electronics, telecommunications, and industrial automation, cable processing requires high precision and quality, and it is carried out using automatic or semi-automatic cable processing machines. The cable processing stages can be summarized as follows:

  • Cutting: Cable cutting machines are used to prepare cables at predetermined lengths. These machines can be manual, semi-automatic, or fully automatic. If you want to closely examine cable production and processing machines, you can visit the Wire Eurasia Wire Exhibition, which will take place from April 9-12, 2025.
  • Stripping: In this stage, the insulation at the ends of the cut cables is removed without damaging the conductors. The stripping process can be partial, complete, or multi-layered.
  • Connector Crimping: In this stage, appropriate connectors are mechanically compressed onto the ends of the cables.
  • Soldering: In some special applications, cable ends or connector connections are soldered to ensure a more secure connection.
  • Cable Bundling and Protection: This process is applied to organize multiple cables and provide mechanical protection.
  • Testing and Quality Control: At the end of the cable processing stages, the produced cables undergo compliance testing.

Cable processing stages generally benefit from technologies like cable cutting and stripping machines, extrusion technology, and testing and control systems.
