CABLE SHEATHS AND WATER PERMEABILITY

Abstract

The degree to which a cable sheath material can protect the interior of a cable from moisture may be determined by simple water permeability tests. Water permeability tests are more reliable for this purpose than water absorption tests, and agree quite well with elaborate cable soaking tests carried out for many months at elevated temperature. Extensive cable immersion data relating 22 materials are given. No rubber or plastic material was found to possess total water barrier capability.
