This course explains the mechanical characteristics of overhead conductors used in the electric utility industry. The course covers NESC requirements and explains the sizing, strength, tension, and other mechanical characteristics of overhead conductors. Sag and tension calculations are presented, as well as methods of checking for sag conditions in the field. Methods to reduce the harmful impacts of wind-induced conductor motions are also discussed. This course is one of several in a series dealing with electrical conductors.

This course is one of four courses on electrical power conductors. The four courses are:

• Electric Power Conductors Volume I: Electrical Characteristics
• Electric Power Conductors Volume II: Mechanical Characteristics
• Electric Power Conductors Volume III: Medium Voltage Cables
• Electric Power Conductors Volume IV: Low Voltage Cables

Each course is written as a stand-alone course and it is not necessary to take them in order. Because they are written as stand-alone courses there is some duplication of material among the four courses.

Learning Objectives

Upon completion of this course, participants will be able to:

• Interpret NESC requirements concerning conductor loading.
• Calculate wind and ice loading on a conductor.
• Compare the different overhead conductor designs.
• Explain the benefits of ACSR conductor.
• Compute conductor breaking strength.
• Describe how sag and tension tables are constructed.
• Determine conductor tensions.
• Mitigate wind-induced vibrations and galloping.

Certificate of Completion

You will be able to immediately print a certificate of completion after passing a multiple-choice quiz consisting of 25 questions. CPD credits are not awarded until the course is completed and quiz is passed.
