Full course description
This course covers the chemistry of the two major polymers used in electric power transmission and distribution cables which are polyethylene and ethylene propylene rubber. The course covers the chemistry of these polymers, their polymerization as well as key properties that are used to define the polymer. We cover polymer modification that is achieved by the addition of fillers and additives to enhance a polymer’s performance as well as discuss polymer crosslinking and stabilization. This includes a review on the chemistry used to impart flame retardance. We review the property tests that are used to characterize a polymer’s properties important for processing into a finished cable as well as the property tests that are intended to assess the properties of the finished cable and associated with installation or end-use.
