Corrosion Evaluation of Underground Telephone Cable Shielding Materials

摘要

Corrosion data are given on the performance of base and plastic-coated metals intended for use as cable shields for buried telephone cable. The materials investigated on specially prepared specimens were buried for periods up to seven years in six different soil environments. Metals tested included homogeneous plastic-bonded and metallurgically bonded laminates. Some specimens were exposed bare (uncoated), while others had plastic coatings or other types of coatings on either one or both sides. Metals studied included aluminum, copper, low carbon steel, and stainless steel alloys.
