摘要： A power cable includes at least two power conductors, at least one earth conductor, and a tubular outer jacket surrounding the power conductors and earth conductor. Each power conductor may comprise a conductive core and an insulating layer surrounding said conductive core. The power conductors may be twisted and contact each other. The earth conductor may have a diameter smaller than the power conductors and may be positioned in the interstitial area between two adjacent power conductors and the outer jacket. The earth conductor may contact the two power conductors along two respective contact lines and the outer jacket along an extrados portion facing outward with respect to the cable. The outer jacket may have substantially constant thickness. The lateral surfaces of the earth conductor may be free from constraints between the contact lines with the power conductors and the extrados contacted by the outer jacket.
摘要翻译： 电力电缆包括至少两个电力导体，至少一个接地导体和围绕电力导体和接地导体的管状外护套。 每个电源导体可以包括导电芯和围绕所述导电芯的绝缘层。 电源导体可能会扭曲并相互接触。 接地导体可以具有小于电源导体的直径，并且可以位于两个相邻电源导体和外护套之间的间隙区域中。 接地导体可以沿着两个相应的接触线和外部护套沿着相对于电缆面向外的外部部分接触两个电力导体。 外护套可以具有基本恒定的厚度。 接地导体的侧表面可以没有与电源导体的接触线和由外护套接触的引线之间的约束。
