Underground transmission is a costly and complicated option for transmission projects. This course will provide an in-depth overview of underground systems, technology, construction, and installation. This is the ideal course for engineers new to underground transmission projects, regulatory staff that needs an overview to evaluate project options and vendors and contractors that support utilities as they build new transmission.

Learning Outcomes

  • Review underground transmission technology and systems
  • Examine the basics of underground design and construction
  • Delve into the details of cable design and manufacturing
  • Review the considerations that affect cable system ampacity
  • Discuss the design, operation and maintenance of solid dielectric cable systems
  • Discuss the design, operation and maintenance of high-pressure fluid-filled cable systems
