Detailed information relating to the design, testing, application and installation of various types of electrical cables in order to prevent the deleterious effect of moisture and chemical ingress and resultant failures in service is provided in this guide. This includes single and multi-conductor cables over a complete range of voltage ratings. Testing criteria and installation methods covered along with many technical references.

This guide provides cable manufacturers and users with extensive information on the design, testing, application, and installation of low, medium, and high-voltage power cables, as well as communication, control and instrument cables that make use of metal-plastic laminates as radial-moisture barriers. This guide addresses additional means of protecting cables from the entrance of moisture through the use of polymeric super absorbent materials for longitudinal water blocking of stranded conductors and other spaces within cables. The alternate use of extruded metal sheaths or bare, longitudinally applied, metallic tapes with sealed seams will likewise be addr...

While metallic sheaths, such as lead and aluminum, have been effective in past years as barriers to moisture, their relative cost, environmental concerns along with installation difficulties have led to the search for alternatives. Alternatively, thin metal-plastic foils are finding application as moisture barriers in low, medium, high, and extra-high voltage power cables. Aluminum, copper, or lead substrates are coated with polymeric coatings on one or both sides and adhesively bonded to the cable jacket or over sheath. The tapes are usually applied longitudinally, with an overlap, or seam, that is adhesively sealed over the core of the cable and under the ...
