Abstract
Designing power transmission poles that ensure uninterrupted power supply and trouble-free operation at minimal cost is an urgent and important task. The article presents the results of research on the optimization of the structural system of an intermediate power line support in a metal design. The type of support was chosen based on a review of statistical data, which showed that the destruction of intermediate supports is the largest percentage of the total number of failures of all supports in the whole. The article presents the results of studies of the effect of the type of lattice of the trunk of a metal intermediate transmission line support of type 1P220-2 on its mass, the number of nodal connections, as well as reliability parameters such as strength, rigidity and stability. According to the results of calculations, a semi-bevel and cross lattice of bent-welded square profile elements has optimal parameters, which is recommended for elements operating on conditional central tension and compression. The dependence of the width of the base of the metal support on its overall height is investigated. It is noted that the large width of the base makes it difficult to install and transport the support, since it affects the length of its lattice elements. The effect of changing the width of the trunk in height on the weight of the support as a whole is considered. It is noted that the constant width of the trunk makes it possible to unify the lattice elements, which reduces the total cost of manufacturing the support.
