This research-based article explores the manufacturing process, materials, applications, and market trends shaping the multicore cable industry in India. It also offers insights on how to select the right manufacturer for your project requirements.
Understanding Multicore Flexible Cables
A multicore flexible cable combines several conductors within one protective jacket. Each conductor carries electrical signals or power to different components within a system. The flexible design allows the cable to bend and move without damage, making it ideal for dynamic environments such as assembly lines and automation equipment.
Manufacturers design these cables to offer superior conductivity, mechanical strength, and resistance to chemicals, heat, and moisture. The flexibility ensures ease of installation and long service life in demanding conditions.

Manufacturing Process of Multicore Flexible Cables
The manufacturing of multicore flexible cables involves precision engineering and stringent quality control. The main steps include:
- Conductor Stranding:
High-purity copper or aluminum wires are stranded together to achieve flexibility and conductivity. - Insulation Process:
Each conductor is insulated using materials like PVC, XLPE, or TPE, ensuring thermal stability and dielectric strength. - Cabling and Twisting:
Insulated cores are twisted together in a specific configuration to minimize electromagnetic interference (EMI). - Sheathing:
An outer sheath of PVC or special thermoplastic is extruded to protect the cable from abrasion, oil, and environmental factors. - Testing and Quality Control:
Finished cables undergo electrical, mechanical, and flame-retardant tests to verify insulation resistance, conductor continuity, and flexibility.
Leading manufacturers follow ISO 9001 and IEC 60227/60228 guidelines to maintain consistent quality and performance.
Materials Used in Manufacturing
Quality of raw materials determines cable performance. Manufacturers use:
- Copper Conductors: Preferred for high conductivity and flexibility.
