Main Stages of Cable Production

Cable manufacturing involves multiple processes that transform raw materials into finished products.

1. Raw material preparation: Copper, aluminium, and other materials are inspected and prepared for processing.

2. Wire drawing: Metal rods pass through specialized dies to reduce their diameter and create wires of the required dimensions.

3. Conductor stranding: Several individual wires are twisted or arranged together to form a conductor with specific electrical and mechanical properties.

4. Insulation: Plastic, rubber, or other insulating materials are applied around conductors to reduce unwanted electrical contact.

5. Cable assembly: Multiple insulated conductors may be combined into one cable according to the product design.

6. Protective covering: Additional layers, including sheathing, shielding, or armouring, may be applied to protect the cable.

7. Testing and inspection: Finished cables undergo electrical, dimensional, and physical checks.

8. Packaging: Approved cables are measured, wound onto drums or reels, labelled, and prepared for transportation.
