Designing underground systems that inadequately manage heat can lead to reduced cable capacity, shortened service life, and increased costs. Yet, there are countless ducted cable systems around the world that operate reliably despite the heat factor.
To see how many are addressing the thermal properties of ducted cable in design and practice, Polywater assembled a small group of experts to discuss the topic of heat generation and dissipation in power cables and the management of heat for new underground cable installation practices.
Grøft Design was used to do the thermal calculations with the help of Marius Engebrethsen and Marcel den Haan. Read the full article at Polywater.
