Underground Transmission – Program 36

Program Overview
Program Description

There are a number of challenges in underground transmission (UT). Utilities need a better understanding of the condition of an aging UT infrastructure, which in many cases has exceeded its 40-year life expectancy, to strengthen existing cable systems and help asset managers with difficult upgrade and replacement decisions. Increased system robustness, higher capacity and longer life will require development and use of newer polymer insulations at extra-high-voltage (EHV) levels with integrated sensors. An ability to exploit the dynamic overload capacity of buried power cables promises better asset utilization at marginal extra cost. Transmission systems must deliver high power quality for the digital society, ideally immune from weather
