Specification

Stages of the cable extrusion process
To make a long story short, the cable extrusion technique entails a structured set of activities that produce high-quality cables with superior performance characteristics. The rest of the section examines the critical steps in the cable extrusion process:

Wire Preparation: The initial stage in this process is wire preparation, which cleans, anneals, and coats conductors made from aluminum or copper to improve their conductivity to electric current and resistance to corrosion.
Insulation Material Selection: The next step is to select an appropriate insulation material according to the cable’s requirements. Examples of insulation materials include but are not limited to, PVC (Polyvinyl Chloride), XLPE (Cross-Linked Polyethylene), thermoplastics, and thermosetting materials.
Extrusion: From this point, the insulator is placed in an extrusion device that heats the material precisely to the required temperature. The insulator is then melted and channeled through a die until it takes the appropriate die shape needed for the wire.
Cooling and Setting: After the extrusion process is completed, the newly formed cable passes through a cooling system to prevent the dissipation of the insulator material. Hence, the cable retains its form and shape.
Jacketing (if necessary): In some situations, additional protection is referred to as the jacket, which is placed over the insulation layer. The material used for jacketing enhances mechanical strength, provides barrier protection from the environment, and offers more safety measures.
Curing and Cross-linking (if required): For some insulating materials, such as XLPE, further processing with curing or cross-linking may be necessary. This increases the material’s thermal and mechanical characteristics, enabling it to withstand high temperatures and offering almost permanent strength.
Testing and Quality Control: Different tests and quality control measures are applied throughout the cables’ extrusion process to ensure that the products conform to the set standards and requirements. These include conductivity tests, resistance tests, and various voltage tests.
Cable manufacturers can meet the ever-increasing demands and requirements of different fields and purposes by combining these stages with stringent quality control measures to produce reliable and well-functioning cables.
