Abstract: There is made the comparative analysis of the theoretical and experimental investigations of a useful operation of fragments of steel tower supports of OPTL 110 kV. Attention is focused on high voltage supports, which are operated in Ukraine. There is described the principle of carrying out static experimental investigations of plane trusses on developed specialized experimental unit, allowing to investigate a useful operation of support fragments of OPTL. There is given a design procedure and design data of a plane pattern support in the software package «SCAD». There is presented numerical results of calculation of the experimental unit with the test model. There are received experimental values of stresses in the lattice components and the horizontal and vertical displacements of attachment knots of lattice diagonal element members. In definition of central displacements there is analyzed a joint operation of the lattice components of experimental patterns, supporting influence of the stretched lattice diagonal element members is taken into account.
Keywords: overhead power transmission line, mode of deformation, static test, experimental unit, metal support, tensometry.
