Abstract

Предлагается электрический кабель, который включает в себя покрытый электрический проводник, полимерный защитный слой, который захватывает любые чешуйки покрытия, первую изолирующую оболочку, расположенную прилегающей к электрическому проводнику и имеющую первую относительную диэлектрическую проницаемость, и вторую изолирующую оболочку, расположенную прилегающей к первой изолирующей оболочке и имеющую вторую относительную диэлектрическую проницаемость, которая является меньшей, чем первая относительная диэлектрическая проницаемость. В другом аспекте настоящего изобретения предлагается способ изготовления кабеля, который включает в себя обеспечение покрытого электрического проводника, экструзию полимерного защитного слоя поверх покрытого электрического проводника, экструзию первой изолирующей оболочки поверх защитного полимерного слоя и экструзию на нее второй изолирующей оболочки. Кабели по изобретению могут дополнительно включать в себя слои проволочной оплетки или даже проводники обратного тока.
