Va. Kaniskin et al., A NONDESTRUCTIVE METHOD FOR DETERMINING THE SERVICE LIFE OF POLYMER-INSULATED ELECTRIC CABLES, ELECTRICAL TECHNOLOGY, (2), 1995, pp. 53-60
A non-destructive method is described for estimating the service life
of radiofrequency cables with polyethylene insulation; a formula is ob
tained which establishes the relationship between the life of the cabl
e and the alpha-relaxation peak displacement of the frequency and temp
erature curves of dielectric losses (tan delta).
