ABSTRACT
Electric transmission lines are constructed to provide a path for electricity to ºow from a generation source to a speciŸc service area or to intertie with the transmission grid. Transmission of electricity is categorized by voltage level and can range from 69 through 765 kV and higher. e majority of new transmission line construction is being done at higher voltages commonly referred to as extra high voltage (EHV) or voltages greater than 230 kV. e higher voltages reduce power losses inherent in long-distance transmission of electricity, thus allowing the system to operate more e£ciently. EHV line construction requires more speciŸc construction procedures and constructor expertise than construction of lower voltage lines.
