If you are unable to attend at the scheduled date and time, we make recordings available to all registrants for three business days after the event

This one-and-a-half-day course is designed to provide an introduction to transmission line concepts, definitions, and common design practices while infusing the technical tools needed to perform the work with the design concepts (PLS CADD Suite, MFAD, etc.). 

The first day will cover an introduction to transmission lines, including:

  • Electrical characteristics of lines
  • Routing and structure spotting
  • Conductor, hardware, and material information
  • Structure loading

The second day will pertain to electrical clearances, code requirements, structure spotting (ruling span vs. finite element), foundation design, and construction methods. 

Special discounts are available if you bring your team so register today!

Learning Outcomes

  • Review what conductors are used based on weather conditions, tensions, & electric loadings
