Difficult snow-stucking Characteristic overhead conductor line

摘要

PURPOSE:To prevent the lowering of snow-adhesion preventing performance even in the case where the water repellent surface is damaged by the friction at the time of manufacturing and stringing a stranded wire. CONSTITUTION:The surface of a structure such as a stranded metal wire and a jumper line or the like, which forms an overhead cable line, is provided with fine irregular rough surface 4. The surface of the rough surface 4 is provided with a coating layer 5 made of ethylene tetrafluoride resin of a low molecular weight, which is transformed to CF3 to the end thereof.
