CORROSION EVALUATION OF SHIELDING MATERIALS FOR DIRECT BURIAL TELEPHONE CABLES,

Abstract

Buried telephone cables used in the Rural Electrification Administration (REA) Program have, since the initial installation, incorporated a copper shield because of its high conductivity and excellent corrosion resistance in most underground environments. To meet this demand REA has set up a cooperative program with the National Bureau of Standards (NBS) to develop and investigate alternate metals or combinations of metals and materials for use as a shield in buried telephone cables. Such a shielding material, in addition to being economical and abundant, should have the following characteristics: (1) High conductivity (good shielding characteristics); (2) Flexible; (3) Easily corrugated and formed; (4) Corrosion resistance to all soil environments; (5) Resistance to gopher penetration.
