CTC Global announced that its ACCC® conductor became the first electric transmission conductor in history to earn a third party certification for CO2 emission reductions resulting from improved energy efficiency. SCS Global Services verified that ACCC conductor reduces CO2 emissions associated with transmission line losses by 27 to 31 percent under certain design conditions compared to conventional steel reinforced ACSR conductors, the 100-year old technology currently used in most electric transmission and distribution power lines.
The ACCC conductor uses a patented hybrid carbon fiber core that is lighter and stronger than the steel core used in conventional ACSR conductors. The composite core and other advanced design features allow ACCC to incorporate 28% more aluminum in the same diameter without a weight penalty, which serves to reduce line losses and associated emission while also providing the ability to double power flow under peak load or emergency operating conditions. Additionally, unlike steel, the ACCC conductor’s composite core does not expand under highly loaded conditions. This serves to mitigate transmission line sag and clearance violations.
