The influence of solar radiation on the temperature regimes of power lines implemented with classical and new types of wires is considered. The maximum permissible temperatures limit the capacity of the lines, and the current temperature regime affects the loss of power and energy due to changes in the ohmic resistance. The paper presents the heat balance equations for insulated and non-insulated wires, formulas for calculating the heat transfer coef-ficient and solar radiation intensity, and an expression for the permissible current. Typical values of direct and diffused radiation are compared, provided that the wire is perpendicular to the sunlight. It is shown that solar radiation leads to an increase in the temperature of the wires by 5 and up to 7 degrees Celsius with a weak dependence on the type of wires and current load. The corresponding increase in real-power losses does not exceed 3%. The results obtained with the proposed technique for non-isolated wires show good convergence with previous studies. One of the advantages of the developed method is its versatility, which is manifested in the possibility of its application not only for non-insulated wires, but also for wires with insulation.

Analizowany jest wpływ promieniowania słonecznego na warunki temperaturowe linii energetycznych z klasycznymi i nowymi typami drutów. Maksymalne dopuszczalne temperatury ograniczają możliwości linii, a warunki temperaturowe wpływa na utratę mocy i energii z powodu zmian rezystancji. W pracy przedstawiono równania bilansu cieplnego dla drutów izolowanych i nieizolowanych, wzory do obliczania współczynnika przenikania ciepła i natężenia promieniowania słonecznego oraz wyrażenie na dopuszczalny prąd. Porównywane są typowe wartości promieniowania bezpośredniego i rozproszonego, pod warunkiem, że drut jest prostopadły do światła słonecznego.
