| Abstract: | The paper introduced theoretical calculation of steady current-carrying capacity for XLPE cable of duct laying,including the cable current-carrying capacity calculation formula under 4 kinds of condition of duct laying,such as single cable;multi cable of equal load and equal section;the cable with different load and line core section;partial cables with equal load and equal section and partial cables with different load and line core section.The comparison with test result of current-carrying capacity for XLPE cable of duct laying in Wuxi Power Supply Co.shows that the error between theoretical calculation and test value does not exceed 7%, which accords with the needs of project. |
| Keywords: | duct laying power cable current-carrying capacity theoretical calculation temp erature rise |
