Abstract:

Technological progress and the emergence of new materials help people develop innovative solutions to meet the challenges of the time. Currently, a line of lighting supports made of polymer composite materials and new production technologies of such products are being actively developed. This is being done so that physical and mechanical characteristics of composite supports could be improved in order to increase their advantages over reinforced concrete and metal supports, as well as to expand the territorial area of use of such supports in various climatic zones of the Russian Federation. This article discusses a trial test of a support made of polymer composite materials in the city of St. Petersburg. The purpose of this study is to determine the characteristics of the composite support, the possibility of its improvement, and the establishment of the possibility of its further use under the overhead power line. In this study, methods of observation and analysis of the results were used. As a conclusion, it can be said that the physical and mechanical characteristics of the mounted support are in full compliance with the stated requirements for composite supports installed in the city of St. Petersburg. In addition, this support satisfies climatic conditions which is important for the entire period of its operation. According to the review of St. Petersburg State Unitary Enterprise “Lensvet”, it can be concluded that the use of this support made of polymer composite materials is only possible with a combined installation with reinforced supports on small streets, alleys and quarters. This support is generally approved by St. Petersburg State Budgetary Organization "Lensvet" and recommended for operation in the city of St. Petersburg.
