С другой стороны, наличие изоляции требует разработки более сложных математических моделей для адекватного описания их поведения и исследования характеристик новых проводов при эксплуатации.</p><p>Приведены результаты использования разработанных математических моделей и программ расчета для сравнительного анализа защищенных и неизолированных проводов в условиях изменения токов нагрузки и погодных условий. Исследованы зависимости температуры и потери активной мощности от толщины изоляции. Показано, что наличие изоляции позволяет при определенных условиях уменьшить температуру и потери по сравнению с проводами без изоляции при прочих равных условиях.</p><p>Полученные результаты могут быть использованы для повышения пропускной способности и надежности линий электропередач.</p></abstract><trans-abstract xml:lang="en"><p>In overhead lines of power supply systems at voltages of 6–110 kV, the use of protected wires is becoming increasingly popular, which have a number of advantages over traditional non-insulated aluminum wires. On the other hand, the presence of insulation requires the development of more complex mathematical models to adequately describe their behavior and study the characteristics of new wires during operation.</p><p>The results of using the developed mathematical models and calculation programs for comparative analysis of protected and non-insulated wires under conditions of changing load currents and weather conditions are presented. The dependences of temperature and loss of active power on insulation thickness are investigated. It is shown that the presence of insulation allows, under certain conditions, to reduce temperature and losses compared to wires without insulation, all other things being equal.</p><p>The results obtained can be used to increase the capacity and reliability of power transmission lines.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>потери активной мощности</kwd><kwd>температура проводника</kwd><kwd>изолированный провод</kwd><kwd>защищенный провод</kwd><kwd>активная мощность</kwd><kwd>воздушные линии</kwd><kwd>сопротивление линии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>active power losses</kwd><kwd>conductor temperature</kwd><kwd>insulated wire</kwd><kwd>protected wire</kwd><kwd>active power</kwd><kwd>overhead lines</kwd><kwd>line resistance</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Energy Outlook 2022 // bp.
