High-Capacity, Energy-Efficient ACCC® Conductor Case Study

By Randy Hurst

This project won EEI Transmission Project of the Year – 2016

Description: 240 circuit miles, 345 kV line, double bundle
Project: Replace 1,440 miles of ACSR conductor with ACCC



  • Improve reliability (reduced sag and corrosion)
  • Increased capacity to serve growth (2X ACSR)
  • Improve grid resilience using high-strength composite core
  • Retain existing structures – to reduce capital costs and timeframe
  • Eliminate down time with live line reconductoring
