A 500‐kV XLPE insulated cable with an insulation thickness of 27 mm has been developed for long‐distance transmission lines. Basic studies on the 500‐kV XLPE cable have shown that contaminants in the insulation may determine electrical performance. This hypothesis is justified by the good correlation obtained between statistical estimations of the size of the largest contaminant in the insulation and electrical characteristics of full‐size cables. Voltage‐withstand and long‐term tests have confirmed design values for minimum breakdown stress, ac and impulse voltage, and degradation coefficients. © 1997 Scripta Technica, Inc.
