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.lLWPVC Cable,PVC insulated Power Cables,Flexible Wire

Insulation is strict as per National and International specification. PVC cables are available as a Thermoplastic dielectric. PVC cables use PVC compound that takes care of overload and short circuit currents with both coarse and fine protection systems.
Laying up: Cores are tested on the line during production both for the physical and electric characteristic. For multi-core cables, cores are laid upon a 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 are compatible with the temperature rating of the cables. Cables are provided with PVC/polymer outer sheath with various characteristics of sheathing compounds.

Conductor resistant test
Thickness of thermoplastic and elastomeric insulation and sheath
Tensile strength and elongation at break of thermoplastic and elastomeric insulation and sheath.
Thermal ageing in the air.
Shrinkage Test.
Ozone resistant Test
Heat shock Test.
Hot deformation Test.
Bleeding Test.
Cold impact Test.
