Electric wires and cables are coated with substance like PVC to prevent from electric shock since PVC is insulator pad conductor of electricity. and it does not conduct electricity it is therefore on excellent material to use for electrical applications such as insulation sheathing for cables.

b) 7 Ways You Can Protect Your Cables From Being Tangled & Damaged
Protect Cables using Vinyl Tubing.
Use a Spiral Wrap to Bundle your Cords.
Insulate Cords using Heat Shrink Tubing.
Use your Pens.
Use Liquid Glue to Solder the Wire.
Apply Liquid Plastic to the Frayed Cords.
Do not Walk on Cables.

9) (1) Cables and accessories. In order to reduce the thermal expansion and contraction of large-section cables, the cable cores should be split conductors, which not only reduces the loss of the core, but also produces less thermal mechanical force per unit area than other forms of conductors.
