IEC 60245-3: Rubber-Insulated Cables — Flexible Cable Standards for Welding and Submersible Pumps

Rubber vs. PVC Cable: The Real Difference Is Application

IEC 60245-3 specifies rubber-insulated cables (up to 450/750 V). Rubber cable flexibility, oil resistance, and heat resistance far exceed PVC — welding cables, submersible pump cables, and port machinery cables are all rubber-insulated.
