One of the primary reasons PVC is used in cable production is its strong electrical insulation properties. Polyvinyl Chloride effectively prevents electrical current from escaping the conductor, which reduces the risk of short circuits and improves overall system safety. This makes it an ideal material for many low- and medium-voltage cable insulation applications.

Many people are surprised that overhead high-voltage power lines often look relatively thin compared with low-voltage distribution cables. The reason lies in the relationship between voltage and current. When electrical power is transmitted at higher voltage levels, the required current decreases significantly. Lower current means less heat generation and reduced energy loss during transmission. Because of this principle, engineers can design HV cable conductors with optimized diameters while still delivering massive amounts of electricity efficiently.
