Transmission Structure Design

March 11 - 12, 2025 Online :: Central Time

“Amazing course, he really took the time to provide us his experience in design.”

El Paso Electric

“To say Chris is knowledgeable is an understatement.  He did a great job conducting the class and knows the material very well.” 

Orange & Rockland Utilities, Inc.

“This course was a refresher of structural analysis material I saw back in school. Good refresher.” 

Project Engineer, RGrid Power

The increase in reliability and efficiency of electric power has prompted the upgrading and building of new electrical transmission lines across North America. Combined with the retiring of experienced transmission structural engineers, it is vital for incoming structural engineers and project managers to become more familiar with the fundamental aspects of design, manufacturing, innovation, and testing of different types of installations. The EUCI Transmission Structure Design course is intended to provide a deep dive into natural wood poles, steel poles and lattice towers.  Concrete and laminate wood poles will be discussed as a cursory review (many concepts from the other structure types can be carried over). 

Our expert instructor will provide a practical overview of transmission structure design, including:

  • Structure loading
  • Industry standards
  • Electrical clearances effect on structure geometry
  • Detailed design considerations
  • Discussions of direct embedded pole analysis, phase considerations and use the of manuals and tools like PLS-TOWER and PLS-POLE.

Learning Outcomes

  • Define and describe the different types of transmission structures and when to use them
  • Identify the necessary loading criteria for which to design
  • Examine the applicable design standards and manuals 
  • Apply structural design fundamentals for latticed self-supporting towers, tubular steel structures, guyed structures, and more  
  • Review basic electrical clearances and how they shape structure geometry and design       
  • Examine the appropriate design software applications  
  • Analyze the different methods of testing and when to apply them 
  • Identify the manufacturing and finishing process for towers, poles, and other structures
