Corrosion of bare and tin alloy coated copper concentric neutral strands has received much attention in recent years. The problem has been evaluated in surveys conducted by NACE, IEEE, REA, EPRI and other organizations and disagreement still exists on the extent of the problem.1-3  Agreement has been reached on the fact that concentric neutrals do corrode and NACE has established task group T-10C-1 to prepare a state-of-the-art report on the corrosion of concentric neutrals on URD cable. This group will report on the extent of corrosion, the mechanisms of corrosion, detection and evaluation of corrosion and methods of mitigation.
