Overhead Electric
and Communication Line Conductors and Cables

Collaborative Learning and the Academy for Utility Line Design Professionals is offering this practical 1/2-day mini-course to help utility line design professionals better understand the physical and electrical characteristics, as well as the engineering design and installation requirements for overhead line conductors/cables.

Course Highlights:

  • What types of electric supply and communication conductors and cables are typically used on overhead distribution lines and why?
  • What are the physical and electrical characteristics of overhead line conductors and cables?
  • What determines the maximum tension that an overhead line conductor or cable will transfer to an overhead line structure?
  • What determines the maximum overhead line conductor or cable sag that must be considered in meeting required NESC clearances?
  • What overhead line conductor and cable design calculations must be made and how should the design be documented?
  • What engineering specifications should be provided and what quality control practices should be used in overhead line conductor and cable installations?

            Course Content:

            • Types and functions
            • Construction and physical characteristics
            • Specifications
            • Overhead line configurations and support hardware
            • Conductor supported hardware and equipment
            • Electrical properties
            • Electrical loading and thermal characteristics
            • Physical loading and conductor forces
            • Sag and tension characteristics
            • NESC requirements for maximum design sag conditions
            • NESC requirements for maximum design tension conditions
            • Conductor and cable design procedure and documentation
            • Engineering specifications for installation
            • Installation methods and quality control practices

            Course Features:

            • Up-to-date information
            • Real-time survey questions and participant Q&A
            • Practical examples of conductor/cable engineering designs
            • Actionable recommendations to improve your conductor/cable design and installation practices

            This course is offered in three (3) parts of approximately 60 minutes each with 15-minute breaks between each part for a total duration of 3-1/2 hours and 3.0 Professional Development Hours (PDHs).
