The other portions of this line, from Deerfield Substation to structure 3, and from structure 113 to Rochester Substation, are constructed of 795 ACSR 36/i conductor. The replacement aspect of this project will remove all of the existing 477 ACSR 18/i (conductor) and 3#6 Alumoweld (static wire) and install new 795 ACSR 26/7 (conductor) and 9#10 Alumoweld (static wire) for the 8.51 mile length of the line between structures 3 and 113. Replacing this conductor will remove an overload condition that will occur when the new transformer at Deerfield Substation is placed in service. On the other portions of the C-i29 line with existing 795 ACSR 36/1 conductor, the conductor and static wires will remain but will be up-rated for operation.”}}
