The ACCC® Conductor
The ACCC® Conductor was the world's first commercially available and most rigorously tested carbon fiber core conductor in the world. It has been selected by more than 250 Utilities and Industrial customers in more than 65 countries for over 1,100 projects ranging from 11 kV AC to 1,100 kV DC. It is, hands-down, the best performing conductor in the world today.
Initially developed to mitigate thermal sag and alleviate grid capacity bottlenecks, the ACCC® Conductor delivers much more. It’s hybrid carbon fiber core offers superior performance and longevity. Its lightweight composite core enables the use of ~30% more conductive aluminum that decreases electrical resistance and line losses. This dramatically improved efficiency is freeing up wasted generation capacity, reducing fuel consumption, and cutting CO2 and other GHG emissions from fossil fired thermal power plants.
The ACCC® Conductor’s ability to double the capacity of existing transmission lines will help the world’s electric power providers deliver reliable and affordable power to people of the world for decades to come.
Thank you to everyone that has supported CTC Global and the ACCC® Conductor’s evolution over the last 20 years. Happy New Year.

The ACCC InfoCore® System
The ACCC InfoCore® System reduces real-world conductor installation risk experienced by utilities, contractors and lineman across the globe. These dedicated professionals know that even with the best tools, equipment and field conditions, accidents can happen. By using a proprietary infrared light system, special fibers in the core, and a robust data-capture and recording methodology, the ACCC InfoCore® System can confirm the integrity of the conductor in minutes. While not mandatory, this capability serves to improve reliability and confidence. The system is capable of confirming very long continuous spans and is currently being utilized globally.
The process begins by accessing the conductor at each end, prepping the core ends using tools provided in the ACCC InfoCore® Verification Kit.
- Prepping tool used on both ends of the section or reel.
-
Transmitter is attached to one end of the ACCC® Conductor.
- Receiver is attached to the other end.
- Controller receives, reviews and records the results.
CTC Global’s ACCC InfoCore® System makes confirming successful conductor installation safe, simple and fast. Alternate methods include CT Scan, X-Ray inspection, and Magnetic Pulse Technology, but these devices are very slow and expensive.
The ACCC InfoCore® System is commercially available and has been deployed to a number of sites worldwide. It is noteworthy that there is no performance difference between ACCC® Conductor and ACCC InfoCore® Conductor. ACCC InfoCore® Field Verification Kits are easy to use, and available through CTC Global’s Master Installers network. For more information please contact CTC Global or email news@ctcglobal.com

PGCB Completes Padma River Crossing with ACCC® Conductor
The Power Grid Company of Bangladesh (PGCB) recently energized a 7.5 km crossing of the Padma River in the district of Munshiganj using ACCC® Dhaka size conductor. It is a double circuit, quad bundle, 400 kV line consisting of 90 km (56 miles) of ACCC® Conductor manufactured by Apar Industries, India. ACCC® Hardware for the project was provided by Dervaux.
The crossing was accomplished using 128 meter (420’) tall lattice towers, spaced 828 meters (0.51 miles) apart. KEC International, Ltd, and Shohel Engineers completed the work in 57 days from start of conductor installation to energization with installation training, supervision assistance and technical support provided by CTC Global and ACCC® Master Installers from Teems India, Ltd.
To quote KEC: "The line enables transmission of reliable power to Dhaka City and further strengthens the country's national grid." The photos below offer a glimpse into the magnitude of this project. Very impressive work by all participants!
