Corrosion Fatigue of the Tail Wire of an Aerial Clamp
The small cable (drop wire) providing service for individual subscribers from the aerial plant is held in place by a clamp made of a tin-coated brass body (attached to the cable) and a copper tail wire loop (attached to a galvanized steel hook or to a porcelain insulator). The tail wire is 2.6 mm (0.102 in.) diam annealed copper, and the clamp assembly must withstand a 2470 N (555 lb) load without breaking or slipping. A number of these clamps, located a few hundred feet from the ocean, have failed. The sharply broken wire indicated to weakening by abrasion....
