Design of Power Cable Lines Partially Exposed to Direct Solar Radiation—Special Aspects

Design of Power Cable Lines Partially Exposed to Direct Solar Radiation—Special Aspects

Power cable lines are usually buried in the ground. However, in some cases, their ending sections are mounted along the supports of overhead lines. This leads to a situation where the cables are exposed to direct solar radiation and, consequentially, overheat. The paper presents the advanced compute...
