Dialysis on a grand scale: Exelon increases capacity of 138-kV pipe-type circuits with forced cooling using reprocessed fluids

摘要

In the past three years, Exelon Corp. (Chicago, Illinois, U.S.) has made great strides in upgrading its transmission and distribution infrastructure in the Chicago metropolitan area. This includes both the upgrading of existing facilities and the building of new lines and substations. This article is the second in a series addressing Exelon's efforts to upgrade transmission infrastructure. The first article, "Casting for a Low-Cost Solution" (T&D World, June 2001) addressed the first phase of Exelon's System Reinforcement Project, the goal of which was to meet the load demands on the north side of Chicago, where the utility installed a new transmission substation.
