Florida Power and Light (FP and L) learned from experience the value of using jacketed cables for underground residential distribution (URD) to protect against corrosion. The original tube-type jackets were replaced with semiconducting extruded jackets as a precaution against punctures. The difficulty of identifying which installations would have corrosion problems led FP and L to jacket all underground cables with a cross-linked polyethylene. Other tests will determine if concentric neutral cables are better suited to underground use than untinned copper neutral wires. Corrosion studies by the Georgia Power Co. have found soil variations to be a key factor and the corrosion selectivity makes prediction difficult. Pennsylvania Power and Light is attacking the corrosion problem by retrofitting underground cables with magnesium anodes. (DCK)
