Why High-Capacity, Low-Sag ACCC Conductor Offers a Better Solution than ACSS

1. Why High-Capacity, Low-Sag ACCC® Conductor Offers a Better Solution than ACSS www.ctcglobal.com Dec 2020

2. Introduction CTC Global is an ACCC conductor manufacturing company that was founded to develop, certify and deploy advanced technologies to improve the efficiency, capacity, reliability and resiliency of the electric power grid. Our primary product is high-capacity, low-sag CTC Global ACCC Conductor solutions. www.ctcglobal.com

3. The globally-patented and trademark-registered ACCC® conductor www.ctcglobal.com CTC began the development of the ACCC conductor in an effort to increase the capacity of congested transmission lines that were constrained due to thermal sag. Essentially, CTC Global recognized the numerous advantages of carbon fiber composite materials and developed – and rigorously tested – a composite core that is about 50% stronger and 70% lighter than steel with a coefficient of thermal expansion about 90% less than steel – it does not sag like steel when hot.

4. About the added aluminum content The added aluminum content and quality increase the conductor’s ampacity – or current carrying capability – to about twice that of a conventional conductor, as well as significantly reducing line losses compared to any other conductor on the market today.  Line loss reductions can range from 25 to 40% or more depending on load level. The improved efficiency of the ACCC conductor along with its ability to carry twice the current of a conventional conductor- without excessive sag – offers huge advantages. www.ctcglobal.com

5. Increased strength, greatly reduced thermal sag ACCC® Conductor, on the other hand, offers increased strength (41,200 pounds for Drake size), and, more importantly, greatly reduced thermal sag. This means that the capacity of an existing ACSR line can be doubled by upgrading to ACCC without the need to replace or modify existing structures. Other performance / durability benefits of ACCC compared to ACSR or ACSS is that ACCC offers greatly improved corrosion resistance as well as resistance to fretting failure and cyclic load fatigue caused by Aeolian Vibration and thermal cycling. Finally, and with great significance, the ACCC conductor’s lighter weight composite core allows the incorporation of 28 percent more aluminum (using compact trapezoidal shaped strands), without a weight or diameter penalty. The added aluminum content and reduced electrical resistance allows the ACCC conductor to reduce line losses between 25 and 40 percent compared to equally sized ACSR / ACSS conductors. www.ctcglobal.com

6. The lowest cost solution Reduced line losses serves to reduce operating costs, fuel consumption (and associated GHG / CO2 emissions) while also freeing up generation capacity that is otherwise wasted. When upfront capital costs, maintenance costs and life cycle costs are considered, ACCC conductor blows away the competition and offers the lowest cost solution, by far. www.ctcglobal.com
