The evolution of corrosion control for lead sheath cable and associated metallic apparatus cases is briefly described. Methods for testing and evaluating existing cable systems are discussed. A case history is presented which delineates the application of cathodic protection for 20 miles of lead cable using deep anodes. The economics of the protect versus replace options are developed which demonstrate that the application of cathodic protection will save the utility $83,800 per year over a 25 year period.
