When you read about the manufacturing of any power cable, you may found that there are distinct types of cables and wires manufactured by the companies. In this article, PVC cables manufacturers will share all technical aspects of PVC Cables i.e. their manufacturing process and major advantages in brief. Let’s read them.
Manufacturing process :
Copper conductor wire of the required size is inserted into the extruder. In the extruder, PVC is coated on the wire to a specific thickness. The extruded wire is coiled on the take off system after passing through the cooling tank. Manufacturers coil the wire into the length of 100m and test their products as per IS specifications.
PVC cables are available as thermoplastic dielectric. Manufacturers use PVC compounds for such cables that take great care of over load and short circuit currents with both fine and coarse protection systems.
Laying up - Cores are tested by the team online during manufacturing process for electric and physical attributes. For multi core cables, cores are laid up on laying machine, which are already equipped with sector correction equipments.
Insulation – The cables after laying up process are offered with insulation of premium quality of PVC polymer, which is softer than the outer sheath and are compatible with cables temperature rating.
Outer sheath – Cables are offered with polymer or pvc sheathing with several sheathing compounds characteristics.
What are the advantages of PVC cables?
There are lots of advantages offered by PVC material based cables. Let’s discuss them –
There are many tests performed by PVC Cable Manufacturers to check conductor resistance, thickness of thermoplastic and elastomeric insulation and sheath, shrinkage, ozone resistance, cold impact, heat shock, bleeding and brimming, etc.
