Calculation of Inelastic Extension of Overhead Power Lines Wires: Theoretical Justification of the «extraction» of Wires.

n the current regulatory literature, there are «gray zones» when there is no effective calculation methodology behind the requirement to take into account a well-known and proven phenomenon in the design. The «extraction» of overhead power lines wires is one of such zones. The article attempts to substantiate this phenomenon on the basis of simple facts known back in the 30s of the last century, which were discarded in the second half of the XX century in favor of a theoretical calculation method that did not receive proper experimental justification.
