This research service analyzes the characteristics of the underground transmission and distribution cables market in North America and the variables that will affect this market during the 2012 - 2016 forecast period. Though most electricity is transmitted through overhead power lines, demand is high for underground cables because they require less maintenance. The three types of cable discussed are power transmission, power distribution, and marine, or subsea. These cables also are distinguished by their insulation types: solid dielectric, fluid filled, and gas filled. Drivers and restraints are discussed. The base year for this study is 2011, and the geographic scope includes the United States and Canada.
