The present report examines the aging processes that may take place in solid-dielectric extruded-type high voltage transmission cables under dry conditions. Particular emphasis is placed on the aging process as affected by the separate simultaneous action of the four main aging factors, namely the electrical, mechanical and thermal stresses, and the physical and chemical environment. A number of pertinent aging models are considered and their validity and applicability to accelerated aging tests on solid-type transmission cables examined. Finally, a number of recommendations are made concerning multistress-aging studies on solid type transmission cables with the purpose of obtaining data and experience that would be helpful in the design and manufacture of such cables in the future.
