Ресурс работы или долговечность металлических конструкций опор ЛЭП является одной из жизненно важных характеристик, необходимых для успешного и безаварийного процесса передачи электроэнергии. Возможность определения ресурса работы металлических опор ЛЭП продемонстрирована в настоящей статье. Методом измерения скорости ультразвука на реальных опорах получена зависимость, позволяющая количественно оценить срок службы. Измерения проводили в Татарии (г. Елабуга).

The paper deals with the durability of metal structures of supports which is one of their important properties necessary for the successful and accident-free operation of electric transmission lines. The criterion of safe operation is determined in the paper using a method of measuring the ultrasonic rate of the real supports. As a result the obtained dependence allows the quantitative analysis of the support lifetime. Measurements are carried out in Elabuga (Tataria).
