In the conditions of constant power consumption increase, the problem of optimizing long-distance energy fl ows transmission needs to be solved. One solution could be the creation of innovative conductors providing transmission capacity enhancement while reducing technical power losses, including corona losses.

Products developed by "Energoservis", LLC and JSC “Severstal” are compacted conductors characterized by increased mechanical strength and current load. In comparison with ordinary conductors, the compacted conductors are twisted and constricted by means of plastic deformation. As a result, the compacted conductor has a higher density in the cross section and conductive electrical contacts between the wires. ASHS and ASHT conductors (high-strength and high-temperature steel-aluminum conductors) <2, 5, 7> are certifi ed for use at power transmission lines by PJSC "FGC UES" interdepartmental commission <1, 2>. The conductors have passed tests on mechanical and electrical parameters, including on corona discharge and its intensity in accordance with IEC 61284:1997 recommendations ("Overhead lines – Requirements and tests for fi tting") <3, 4, 5>. Comparative analysis of test results is considered below.
