In the world of commodity transmission conductors, conductor efficiency is generally not considered to be high on the priority list. Conductor selection is generally based on load considerations. But times are changing. Looking back a few years, consider the substantial investments that were made to improve the efficiency of generators to reduce fuel consumption and/or help improve the economic viability of competing generation technologies such as solar and wind. Improved transformer technologies, while slightly more expensive, were also easy to justify – as they offered reduced lifecycle costs and improved efficiency.
On the demand side, consider that billions of dollars have been spent to improve the efficiency of demand side appliances such as refrigerators, air conditioning units and even light bulbs. On the conductor side, very little consideration historically has been given to conductor efficiency and line losses as these costs are generally passed through to the consumer.

The capacity advantages CTC Global’s ACCC Conductor 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. CTC Global's ACCC Conductor High efficiency.
Over the past few decades, changes in weather patterns due to climate change or global warming have led to more extreme, frequent, and costly weather events that have included intense rains, ice storms, tornadoes, floods, hurricanes, heat waves, droughts, and wildfires. These events have caused hundreds of major power outages which have closed schools, shut down businesses, Impeded emergency services, and cost the economy hundreds of billions of dollars. In an effort to combat the growing problem, many utilities are developing strategies to modernize and “harden” the electric grid. New initiatives are directing substantial investment to improve the grid’s efficiency, capacity, reliability, and resiliency.
These efforts will not only help make the grid less vulnerable to weather.related outages, they will also help reduce the time it takes to restore power after this number-one cause of outages occurs.

Following the Western Energy Crisis of 2000 and the Major East Coast Blackout of 2003, a group of engineers in California got together to design a new type of bare overhead conductor that could carry twice the current of a conventional conductor without exhibiting excessive conductor sag. The team essentially replaced steel core strands, used to strengthen most types of overhead conductors, with a composite core made up of high-strength carbon and glass fibers. The composite core offered a coefficient of thermal expansion nearly ten times less than steel.
This allowed the ‘new’ conductor to carry very high levels of current during peak load and/or emergency conditions without sagging into underbuilt lines, trees or other structures. To date, the new conductor has been deployed to more than 430 projects in 40 countries, primarily to increase the transmission lines capacity of the existing lines. Increasing line capacity offers several advantages. CTC Global software helps in improving the efficiency, reliability and capacity of grid.
Challenged by an increase in demand for affordable electricity, many system planners and transmission engineers are being asked to find economical ways to reduce grid congestion and improve grid reliability. In many cases, grid congestion costs the utilities and the customers they serve tens to hundreds of millions of dollars annually. Restrictions on new line permitting and advances in conductor and related technologies have changed the options available to planners and engineers trying to solve these problems; until the introduction of CTC Global Software, however, there have been limited design tools available that can help illustrate the differences between multiple conductor solutions. Grid congestion is often described as a condition where existing lines are no longer capable of importing power from less expensive and often remote sources of generation, forcing utilities to develop and use more expensive, local sources of generation.
CTC Global’s ACCC Conductor improves overall efficiency and capacity of the grid. Initially developed to increase the capacity of existing transmission and sub-transmission lines, the patented and trademark registered ACCC® Conductors were commercially deployed in 2005. The CTC Global ACCC Conductor utilizes a high-strength, light-weight composite core to replace conventional steel core wires in conventional bare overhead conductors. The composite core offers a very low coefficient of thermal expansion to mitigate conductor sag under heavy electrical load conditions.
The composite core’s greater strength and improved dimensional stability also enables increased spans between fewer and/or shorter structures to minimize environmental impact on new transmission lines. The ACCC Conductor’s lighter weight composite core further allows it to incorporate up to 30% more conductive aluminum which not only helps increase line capacity, it also helps reduce line losses by 25 to 40% or more.
