Quick
Facts
Top
Overview
This project will...
-
Upgrade approximately 10.6
miles of a 115 kV
electric line
between the Sheldon and
Rokeby
Substations.
-
Replace a 48-year-old 115 kV
electric line that is in
deteriorating condition.
The existing electric line was installed in 1961
and has reached the end of
its useful life. The
proposed construction will
improve
reliability by
replacing the existing
wood
H-frame structures, which
have deteriorated.
-
Increase the
capacity rating
of the line.
-
Install a
fiber optic
shield wire between
substations, enabling faster
automated switching.

Construction Details
-
Replace poles and wire for
the 115 kV electric line
between Sheldon and Rokeby
Substations. The new
electric line will follow
the same route as the
existing line and will be
constructed on
single shaft steel poles. A 3.3 mile
section of line at the south
end was rebuilt with wood
poles in 2004. Those poles
will not be replaced.
