One of the main problems typical for Republic of Sakha (Yakutia) power system is a high percentage (more than 60%) power lines wear. More than 70% lines have been operating for more than 25 years, there is a massive decay of the supports and their destruction. Periodic freezing and thawing at the upper boundary of permafrost leads to support piles expulsion, as a result, to their fall and occurrence of a high accident rate in networks. The main goal of the work was to develop foundation solutions (FR) design from composite materials for single- and double-circuit, intermediate and anchor supports with wooden and concrete posts, excluding buckling of supports of 6, 10, 35 kV overhead lines.
