Medium voltage line designers have numerous challenges and obstacles when designing a power line. These include, but are not limited to terrain, weather, routes, density (rural, suburban, urban, etc.) and pre-existing conditions, such as whether an existing pole line already exists and must be utilized. The design options normally include whether to use bare wire, underground cable, or one of two covered conductor options (tree wire or spacer cable).

Oftentimes line design is relatively straightforward, with span lengths pre-determined, and the decision whether to go overhead or underground already made. While long spans are quite common in transmission line design, they are less so in medium voltage. The long spans addressed in this webinar have to do with challenges such as being inaccessible from a bucket truck.

Long spans may arise due to the fact that the line needs to cross a river or stream, or perhaps a rail line, or even traverse from one mountaintop to an adjacent mountaintop. The objective of this webinar is to discuss some of those challenges, how they are addressed by the NESC, various construction option considerations, and the pros and cons of using a Hendrix Aerial Covered Conductor construction.


Brian Trager
Director of Technology & International

Brian J. Trager is a Senior Life Member of the IEEE. He received his B.S. and M. Eng. degrees in Electric Power Engineering from Rensselaer Polytechnic Institute in New York in 1978 and 1980, respectively, and a Masters degree in Business Administration from the University of Pittsburgh in 1986. Mr. Trager has held various positions in Engineering, Consulting and Management at American Electric Power Company, Cooper Power Systems and Fisher-Pierce, and most recently at Hendrix Wire and Cable, where he is currently employed as Director, Technology & International. He has taught Electric Power Engineering at Ohio State University, West Virginia University, and Pennsylvania State University, in addition to teaching courses to utility clients, and has authored over 75 technical papers and articles for the IEEE and other national and international organizations.

With regard to electric power line specification, design, construction and management, Mr. Trager has worked on projects funded by international aid organizations (USAID, ADB, JBIC, and others) to meet growing demand worldwide through the expansion of electric power infrastructure. He has brought to fruition numerous high-reliability power distribution projects in various sites on seven continents over a period spanning 44 years, and for the past 28 years solely dedicated to Aerial Covered Conductor Systems.
