Abstract
A rapid method is proposed for estimating the service life of electric cables with polymer insulation. On the basis of investigating polyeth ylene insulation in the initial state and after holding at a high temp erature, a formula is obtained which establishes the relationship betw een the cable service life and the position of the alpha-relaxation pe ak on the frequency dependences of dielectric losses. Frequency depend ences of the tangent of the angle of dielectric losses (tan delta) are also obtained. (C) 1997 Elsevier Science Ltd. All rights reserved.
