About this document

Cable Ratings on Riser Poles and Shafts by Stefanos Diamantis is a document available to read on EtoBox.

This document reviews methods for rating cables installed in various configurations: (1) on riser poles, (2) in open or closed trays, (3) wrapped in fire protection covers, (4) in horizontal tunnels, and (5) in vertical shafts. The rating is determined by solving energy balance equations to find the surface temperature for a given conductor current. Heat transfer includes natural convection, forced convection from air flow, and radiation. The same equations can be used for all configurations by adjusting co
