Efficiency of Implementing Domestic Innovative High-strength and High-temperature Steel-Aluminum Сonductors

PJSC «Rosseti» maintains 44 thousand km of new conductor types or 1% of the total conductors’ length (4.5 million km). Self-supporting insulated wires of various modifications (more than 41 thousand km or 0.9% of the total conductors’ length) and bare conductors (less than 3 thousand km or less than 0.1% of the total conductors’ length) are among these conductors. In addition, Russian modern power grid is characterized by physical deterioration and obsolescence of equipment. As a result, low energy efficiency of power facilities takes place. The most important indicator of power system efficiency is the level of energy losses. With the growing power losses in electrical networks, the number of urgent problems increases. Reconstruction and technical re-equipment of electrical networks, application of advanced technical developments in design solutions, implementation of modern technologies and materials increasing reliability, durability and maintainability of power transmission lines are among these problems.
