Abstract :
It is shown that the AC breakdown strength and dielectric loss of unaged and field-aged transmission and distribution cables vary with insulation crystallinity, contamination, and oxidation. It is also shown that the influence of these parameters is particularly important near the conductor shield and varies with aging. The influence of curing on cable properties is briefly discussed. The sample preparation, crystallinity, impurity, oxidation, AC breakdown, and dielectric loss measurements are described
