Abstract

Abstract: Poly(vinyl chloride) (PVC) is one of the most popular and widely used materials for electrical cables that offers insulation and sheathing. It is considered agile and durable as it easily exceeds 25–30 years while being used for household wiring. PVC provides insulation, strength, and protection at a wide range of operating temperatures. During cable manufacturing, plastics are exposed to heat that leads to degradation. Although degradation cannot be eliminated, it must be held to a minimum to keep the quality of the final products high. In this work, locally available single strand plasticized PVC insulations that are used for domestic electrical wiring and lighting purposes are investigated for their initial plasticizer content. The thermal‐induced degradation process is a moderate process that would take years to estimate the lifetime of a cable under ordinary ambient conditions. Thus, the study is carried out in accelerated conditions.
