Calculations of Ampacity of 6-35 kV Cable Lines
Abstract
When designing power cable lines (CL), one of the tasks is the thermal calculation of the CL and the selection of a suffi cient cross-section of the core, taking into account the bonding type of the screens and the cable laying conditions. For 110-500 kV high-voltage cable lines, such a calculation is carried out as responsibly as possible, using computer programs, whereas for 6-35 kV medium-voltage cable lines, the project is often limited to a simplifi ed selection of core cross- section, based on catalog values of permissible currents and a system of correction factors. The article demonstrates that this approach to selecting a 6-35 kV cable lines can lead to noticeable errors.
