2 ACCC Aluminum Conductor Composite Core ACCC conductor (Aluminum Conductor Composite Core) is a high capacity, low sag conductor which consists of a carbon fiber composite core encased in a protective fiberglass sheath that is helically wrapped with high purity conductive aluminum strands. ACCC conductors combine efficiency and increased current carrying capacity to deliver more power with less losses based on equal conductor size and weight. Hence, ACCC conductors used widely for reconductoring to increase current carrying capacities, river and forest crosses in transmission and distrubion companies. ACCC conductors also preferred due to reduced line losses, high current carrying capacity, increased span with less structure for new transmission and distrubution systems. It was developed and patented by CTC Cable Corporation, now CTC Global. ACCC is a registered trademark of CTC Global. EMTA manufactures ACCC conductors under license of CTC Global. Up to twice the Capacity of AAC, ACSR and Others Increased Spans on Fewer / Shorter Structures Reduced Line Losses by 25% to 40% or more Greater & Reduced Sag Lower Overall Lifecycle Costs Corrosion Resistance Improved Longevity Installed by more than 150 Trasnmission & Distrubution companies worldwide, over km of commissioned lines at nearly 350 project sites,over 30 countries by A proven and appropriate technology for the modern grid. Greater, Lighter Weight, Reduced Sag The Hybrid Carbon Composite Core is 40% stronger and 70% lighter than a conventional steel core conductor, has 10 times less coefficient of thermal expansion, thus, greatly improving sag performance and the overall reliability of the grid. Longer Spans with Less Structures The greater strength, improved dimensional stability, and an effective self-damping and superior fatigue resistance capabilities allow for increased spans between fewer or shorter structures. By reducing the number or height of required structures, a serious reduction is created in the overall project cost and construction time while minimizing environmental impact. Ampacity ACCC carries twice the current of a conventional conductor making it ideally suited for increasing the capacity of existing transmission and distributions lines without the need to reinforce or replace existing structures, since the light Carbon Composite Core allows the use of 28% more aluminum without a weight penalty using compact trapezoidal strands. Reduction in Line Losses Under equal load conditions, the ACCC reduces line losses by 25 40% when compared to that of conductors with same diameter and weight due to its higher aluminum content, which is fully annealed Type 1350-O aluminum.

3 ACCC Aluminum Conductor Composite Core The aerospace grade carbon fiber composite core surrounded by glass fibers, encapsulated in specially modified high temperature resistant polymeric resin offers greater strength and line loss reductions. ACSR ZTACSR Round Aluminum Wires ACCC technology is based on replacing the heavy steel core of traditional electrical transmission conductors with a high strength, light weight carbon fiber composite core and is applicable for voltages range from 20 kv to 1000 kv or more (AC or DC). The lower Coefficient of Thermal Expansion creates less sag at high temperatures and is resists degradation from vibration, corrosion, ultraviolet radiation, corona, chemical and thermal oxidation, but most importantly cyclic load fatigue.

Structure changing, replacing advantages and other advantages that ACCC provides were not taken into consideration. An initial investment of US$ 2.1 mn in the technologically advanced ACCC conductor, generates US$9.81 mn of savings from the reduction in line losses over the first 15 year of service.
