Abstract

A detailed examination of the aging processes, that may take place in solid-dielectric extruded-type high voltage transmission cables under dry conditions, is presented. Particular emphasis is placed on the aging process as affected by the separate and simultaneous action of 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 are discussed
