P1235 - Guide for Properties of Stripes and Ridges for Identification of Underground Power Cable Jackets and Ducts
Project Details
This guide provides recommendations for colored stripes and raised ridges as identification markings on non-conducting and semiconducting underground power cable jackets. Typically, power cables are identified by red stripes, however, other colors may be permitted. The guide also applies to the duct containing jacketed or unjacketed underground power cables. The colored stripe recommendations include the number of stripes, color, width, thickness, color retention characteristics, physical properties, storage criteria, and test methods. The raised ridge recommendations include physical properties, width, height, and circumferential spacing. It is the intent of this guide to provide a minimum level of physical, chemical, and color stability of colored stripes used to identify underground power cable jackets and ducts.
