<P>PROBLEM TO BE SOLVED: To provide a low corona electric wire which prevents corona discharge and corona noise effectively by preventing adhesion of raindrops to an overhead transmission line strands or accumulation of moisture content in the overhead transmission line, and to provide the strand for a low corona electric wire. <P>SOLUTION: On the surface of each strand 2 composing the conductor 1 of an overhead transmission line, a super water-repellent film 3 is formed by super water-repellent treatment. Each conductor 1 of an overhead transmission line includes a core 10 composed of a plurality of strands 2, an inner layer 20 and an outer layer 30. Each strand 2 composing at least the inner layer 20 and outer layer 30 is subjected to super water-repellent treatment. <P>COPYRIGHT: (C)2012,JPO&INPIT |
