Abstract :
Poly vinyl chloride (PVC) is the most popular insulating materials for electrical wiring instruments. The exothermic reaction at over 150°C may cause deterioration of insulating properties in the PVC. Therefore, it is important to clarify heat degradation in the PVC, not only to investigate ignition of electrical wiring instruments but also to use electric products safely. By the degradation of ultraviolet ray to the PVC, it is known that the PVC is deteriorated, and the conductivity is increased.
