Abstract

Communication lines are usually composed of steel and other metallic components. For preventing corrosion of steel wire strands, Zn coating had been used. However, it became appear that some steel wire strands located in coastal areas still had been corroded. That was because air bone sea salt particles above the ocean are blown by the wind and adhere to the surface of metals. To protect steel wires against the atmospheric corrosion, Al coating was applied because of its higher corrosion resistance compared with that of Zn coating. This coating above still corroded which were at the coastal areas. Previous studies on this phenomenon showed that corrosion occurred in the interspace between the sealing tape which was used to inhibit the penetration of rain water and the wire strands. Since Japan is an island country and is surrounded by the sea, investigating the appropriate coatings for steel wire strands is important. We conducted the exposure test and compared three types of coated steel wire strands to investigate the effects of sacrificial anode on the corrosion in Miyake Island over 23 years.
