Three-phase power cable system for adjusting length of high voltage cable, has compensation cables connected to shield of single-conductor cables, where length of compensation and neutral path cables is equal to partial amount of length

摘要

The system has single-conductor cables (10.1-10.3) provided with a metallic cable shield (24) and divided in longitudinal sections (A1-A3). Length (l0) of two of the sections is same, and length of other section is larger than a partial amount of length (Delta l). A compensation cable and a neutral path cable are assigned to one of the single-conductor cables in an extended section, where the length of the compensation and neutral path cables is equal to the partial amount of the length. The compensation cable is connected to the cable shield of the single-conductor cables.
