【 摘 要 】

In order to analyze the effect of internal Cu return conductor on ampacity, this paper establish three types of single core submarine power cable and calculate losses and thermal resistances. Results show that the internal return conductor can effectively reduce the cable loss, thereby increase the cable current carrying capacity. Cable with separated return conductor shows highest ampcity. When section area of return conductor increases, ampacity of cable improves correspondingly.
