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.
