Manzana 35-KV

The Manzana single- and double-circuit 34.5-kV overhead lines total approximately 5.5 miles long and were built with polymer horizontal post insulators and single-wood pole structures. The design includes two-pole structures for medium and large line angles. All angles and deadends are guyed. The conductor is one 1272 kcmil AAC Narcissus per phase, carrying a peak load of 50 MW per circuit. OPGW (fiber optic shield wire) was used for the entire line.

Special pole placement and guy arrangements were required at the crossing of the San Andreas Fault.

All construction was in compliance with APLIC Avian Safety requirements.

TriAxis completed the overhead line design on an expedited basis. TriAxis also provided engineering support during bidding and construction.

The Seneca lumber mill in Eugene, OR, continues to expand and increase load. The plant has outgrown the single 12.5kV feeder providing it power. TriAxis worked with the local electric utility, Blachly-Lane Electric Cooperative, to investigate and develop concepts and designs for providing the mill with two sources of power, each fully capable of serving the entire load. Having two sources will simplify maintenance, allow for plant growth, and allow the utility to readily move load between the two sources. The conceptual design is complete, overhead line rebuilding is underway (December 2014).

Completion Date: 2012

Design work for which TriAxis was responsible: 100%
