7. High Temperature Sag Comparison
ACCC’s Exceptional High Temperature, Low Sag Capability
Comparison Conductors
The amount of sag in a conductor is influenced by the thermal expansion coefficent(s) of the material(s) in the conductor. CTC’s composite core in the TransPowr ACCC/TW conductor has an extremely small coefficient of thermal expansion. Therefore, as the conductor temperature rises, the sag characteristics of the conductor remains virtually constant.
We’ll be looking at ACCC cable benefits in detail throughout this presentation. ACCC cable is superior to existing ACSR and ACSS cable in a number of key performance areas. These performance advantages address critical problems plaguing the utility industry and offer significant benefits to electric utility companies and ultimately to their industrial, commercial, and residential customers. Besides doubling ampacity and virtually eliminating high-temperature sag, ACCC’s non-metallic core doesn’t contribute to inductive heating. The annealed aluminum strand wires in combination with the composite core exhibit excellent self-damping characteristics.

8. Comparison Conductors
Lower I2R Power Losses
ACCC Has Lowest I2R Power Losses
ACCC’s greater aluminum content enables higher conductivity and lower resistance properties, lowering I2R power losses.
ACCC/TW cables are designed to maintain the same overall diameter as conventional ACSR with a weight slightly lower. The compact trapezoidal conductors, coupled with a smaller composite core, result in a TW conductor that has approximate 28% (actually a nominal 28.3% increase) more aluminum cross-sectional area than ACSR.
The composite core has up to twice the strength of conventional steel core and will not rust, corrode or cause electrolysis with aluminum conductors or other components.

ACCC-ACCR-ACSS-ACSR Comparison
This slide presents a comparison between CTC’s ACCC cable and 3M’s ACCR and conventional ACSS and ACSR cables respectively. It’s important to note the significant difference in Total Rated Strength (ACCC = 41,000 lbs) that is driven by the core Rated Strength (ACCC = 38,000 lbs) of the cables. Please note the dramatically lower sag for our ACCC cable.

As I mentioned earlier, CTC has had extensive theoretical and FEM (Finite Element Modeling) modeling conducted by research groups at institutions such as USC and Alpha Star on its ACCC cable.
There has also been extensive testing done by leading industry test institutions such as Kinectrics and EPRI (Electrical Power Research Institute).
All of this is in addition to testing conducted by CTC and our partners such as FCI/Burndy and General Cable.
The results of all of these tests to date validate the performance of our cable, its strength, the superior performance of CTC’s high-temperature compression hardware, and high expectations on their long-term performance.

16. History of the ACCC Conductor
CTC began ACCC conductor development in 2001
CTC composite conductor core testing initiated 2003
General Cable begins wrapping aluminum wire around CTC’s core to produce ACCC/TW conductor in 2003
FCI/Burndy strategic relationship formed in 2004
CTC Cable Corporation subsidiary begins commercial production in 2004
HCTC was founded in 2001 with the mission to bring advanced composite technology solutions designed to address urgent problems in the US power grid.
The first composite core was manufactured at CTC facilities in Irvine in the 3Q03. Composite core manufacturing has continued since then on a continuous basis. The initial core was stranded by General Cable in the 3Q03. In addition, CTC developed an extensive certification protocol for its cable and high-temperature installation hardware with industry leaders Kinectrics and EPRI solutions. The testing started in 4Q03 and is ongoing in reflection of our commitment to providing the highest performance and quality products in the industry.
CTC’s first significant commercial agreement was for a 21 mi. line at an Aquila site in Kingman, Kansas. The agreement was for ACCC cable and the development of a composite pole manufacturing facility to be located in Kingman.
The first installation of ACCC cable was at the EPRI facility in Haslet, TX. Great Southwestern Construction, with the help of CTC technical staff, installed 2 miles of ACCC “Drake” conductor. The installation validated CTC’s installation procedures and illustrated the ACCC was as easy to install as conventional cable. Subsequent commercial installations occurred in 3Q04 with National Grid in New York state, and APS in 1Q05 in Arizona.
