Increase capacity with ACCC Conductor
CTC Global’s ACCC® conductor was developed to increase capacity and carry twice the current of conventional all-aluminum and steel reinforced conductors. While classic AAC, AAAC and ACSR conductors were limited to operating temperatures of ~90°C, other high temperature conductors such as ACSS, Invar and GAP were also designed to carry twice the current as well. The capacity advantages CTC Global ACCC offers over the alternatives is based on CTC Global’s patented composite core which has a coefficient of thermal expansion about 90% lower than steel core strands. So while other high-temperature conductors can operate at higher temperatures while carrying more current, CTC Global’s high-capacity ACCC conductor mitigates thermal sag. This makes it an outstanding choice for increasing the capacity of existing transmission and sub-transmission lines without the need to replace or reinforce existing structures.
Added line capacity offers several advantages. The ability to use CTC Global’s ACCC conductor can, in some cases, mitigate the need to build additional transmission lines. Added capacity can also reduce grid congestion. Grid congestion can substantially drive up wholesale and retail electrical costs and prevent access to the cleanest source of generation. The added capacity offered by CTC Global’s ACCC conductor can also improve grid reliability and prevent very costly power outages. For instance, should an adjacent power line go out of service for planned or unplanned reasons, CTC Global’s ACCC conductor can handle the extra load to make sure that the power needed is delivered.
As climate change continues to increase the frequency and severity of weather related events, the added capacity offered by CTC Global’s ACCC conductor is more important than ever to prevent outages and the extreme economic impact. Delivering clean, efficient, affordable and reliable energy is what drove CTC Global to develop, test and commercialize the ACCC conductor. Without it, we can’t pump water to grow crops, manufacture products to compete in a growing global economy or improve the quality of life for millions of people. When you need added capacity, think ACCC conductor.
