Stranding is a process where multiple metal wires (usually copper or aluminum) are twisted together in a specific direction, pitch, and layer configuration to form a stranded conductor.
Insulation involves coating the conductor or stranded wire with insulating materials to achieve electrical isolation.Materials: Polyvinyl chloride (PVC), cross-linked polyethylene (XLPE), rubber, etc., selected based on voltage rating and environment.
Cabling is the process of twisting multiple insulated cores into a cable core according to a designed structure (e.g., circular, sector-shaped), often with filling materials to ensure roundness.

Sheathing is the final process of coating the cabled core with protective materials.Materials: Polyvinyl chloride (PVC), polyethylene (PE), metal tapes, etc., chosen based on protection requirements.
