P1142 - Guide for the Selection, Testing, Application and Installation of 300 V to 500 kV Cables Having Radial-Moisture Barriers and/or Longitudinal Water Blocking
Project Details
This guide provides cable manufacturers and users with extensive information on the design, testing, application, and installation of cables that make use of radial-moisture barriers and/or longitudinal water blocking. Cable types addressed are rated from 300 v to 500 kV and include power, communication, control and instrumentation cables. This guide addresses means of protecting cables from the entrance of moisture through the use of polymeric super absorbent and other materials for longitudinal water blocking of stranded conductors and other spaces within cables. The use of metallic sheaths and longitudinally applied, metallic tapes with sealed seams will likewise be addressed.
