● Copper or aluminium conductors: Select copper or aluminium conductors suitable for high-voltage or low-voltage applications. Copper conductors are typically used for high-voltage cables.

● Wire Drawing: Copper or aluminium materials are drawn into wires of the required specifications.
● Stranding: Multiple fine wires are stranded together to increase mechanical strength and reduce resistance.

● Using an extruder to uniformly coat the conductor with insulation material to form an insulation layer.

● Conductor Stranding: Twisting multiple insulated conductors together to form the basic structure of the cable.
● Filling: Adding filler material to the cable to maintain its roundness and reduce air gaps.

● Sheath Layer: Extruding an additional layer of sheath material over the cabled structure to provide extra protection.

● Steel tape armouring: For high-voltage cables, steel tape armouring may be incorporated to enhance mechanical strength and resistance to electromagnetic interference.
● Steel wire armouring: Steel wire armouring is occasionally employed, particularly where additional tensile strength is required.

● Conductor resistance test: Ensures the conductor's resistance meets specification requirements.
●Insulation Testing: Inspect the integrity and electrical performance of the insulation layer.
●Sheath Testing: Verify that the physical and electrical properties of the sheath material meet the required standards.
