CTC Global History

Market need drove us to innovate

Recognizing the enormous challenge of increasing transmission line capacity, mitigating thermal sag, and improving conductor efficiency, CTC, of Irvine, California, USA, (now CTC Global) began developing the patented ACCC® Conductor in 2002. The objective was to develop a conductor that could be used to upgrade existing transmission corridors without structural modifications. This objective relied on the incorporation of highly evolved aerospace technology and materials science to create a new higher-strength, lighter-weight core that could incorporate additional conductive aluminum without a weight or diameter penalty, and be utilized to reduce thermal sag, increase spans between fewer structures, carry more current, reduce line losses and improve grid reliability.

After an extensive R&D, testing and installation trials effort, CTC Global went on to develop ISO certified manufacturing techniques and tooling to allow the cost-effective and continuous production of the pultruded composite core. To date, the ACCC Conductor has been deployed to over 700 project sites, globally.
