Abstract: The article discusses the issues of improving static testing of steel poles of power transmission lines. Currently, steel supports made according to individual designs are used in the construction of power transmission lines in order to increase their economic efficiency. To approve an individual project, an experimental support must pass full-scale static tests for design loading schemes. The tests are carried out on specialized stands in accordance with domestic and foreign standards using experimental methods for studying the stress-strain state of building structures and structures. The tests of the support are carried out in the design position. In order to significantly reduce the testing time and cost, the support was tested in a horizontal position on the power floor of the testing hall of the Laboratory for Testing Building Structures and Structures of the DONNASA Federal State Budgetary Educational Institution. The tests were carried out taking into account the experience of testing reinforced concrete racks of power transmission lines. The test results of the prototype of the P10GI-4M support confirmed its design performance. All support elements and nodal joints as a whole withstand the maximum load without residual (plastic) deformations.

Keywords: power transmission line, steel support, static tests, field tests, loading scheme, normal and emergency mode, stress-strain state.
