The main properties of modern ethylene-propylene rubber (EPR) compounds used for the insulation of medium and high voltage power cables are reviewed. These properties have been evaluated both by specific tests on samples of insulation and by comprehensive tests on full size cables. By means of proper compounding and processing, unusually good mechanical, thermal and electrical properties, as well as a high resistance to the normal environmental conditions can be obtained with EPR elastomers. As a conclusion, the results obtained show that EPR provides a cable insulation with outstanding performance.
