How To Start PVC Cables Making Business | SkillsAndTech
A cable comprises two or more wires which are bonded, twisted, or braided together to form an assembly. The wires and cables are encapsulated with non-conducting plastic materials, usually, PVC or polyethylene, to impart protection to users and the surrounding environment.
PVC cables are major equipment for the transmission & distribution of electrical power. They are suitable for use in substations, distribution systems, Industrial installations, house wiring, street lighting.

PVC Cables Manufacturing Process
Copper conductor (wire) of the required size is fed into the Extruder wherein PVC is coated on the wire to the specified thickness. The extruded wire after passing through the cooling tank is coiled on the take-off system. The wire is coiled into the length of 100 meters and tested as per IS specification.

Insulation is strict as per National and International specifications. PVC cables are available as a Thermoplastic dielectric. PVC cables use a PVC compound that takes care of overload and short circuit currents with both coarse and fire protection systems.
Laying up: Cores are tested on the line during production both for the physical and electric characteristics. For multi-core cables, cores are laid upon the latest laying machine, equipped with sector correction equipment.

Laid-up cables are provided with insulation of high-quality PVC polymer which is softer than outer sheath and is compatible with the temperature rating of the cables. Cables are provided with PVC/polymer outer sheaths with various characteristics of sheathing compounds.
The final step is testing. Cables are undergone the following tests:
- Conductor resistant test
- The thickness of thermoplastic and elastomeric insulation and sheath
- Tensile strength and elongation at break of thermoplastic and elastomeric insulation and sheath.
- Thermal aging in the air.
- Shrinkage Test.
- Ozone-resistant Test
- Heat shock Test.
- Hot deformation Test.
- Bleeding Test.
- Cold impact Test.
- Water absorption test (electrical)
- Environmental stress cracking test
