5. Its hybrid carbon fiber core is 70% lighter and 50% stronger than steel. Its has a
coefficient-of-thermal-expansion about 10 times less than steel. This allows the
use of 28% more aluminum which helps increase capacity, improve efficiency &
mitigate thermal sag.
High Performance Conductor for a Modern Grid
ACCC Conductor

6. ACCC® Conductor…
6
• Increases the capacity and efficiency of new and existing transmission lines
• Carbon and glass fiber core provides very high strength (310 to 375 ksi)
• Lighter weight core allows 28% more aluminum without weight penalty
• Very low coefficient of thermal expansion reduces thermal sag
• Composite core resists corrosion and cyclic load fatigue
• Added aluminum content decreases electrical resistance and line losses by ~ 30%
• Core is produced to ASTM Standard B987 / B987M – 17
• Available through 25 authorized manufacturing partners

7. Broad Range of Applications
• Reconductor Projects – increase corridor capacity, reduce environmental
impact, permitting, and capital costs by retaining existing towers
• Rebuild Projects – When its determined that existing structures are too
old or when storm hardening is required
• New Lines – reduce upfront capital costs by increasing spans between
fewer and/or shorter structures
• Generation Tie Lines – increase asset efficiency and investment returns
• Long Span Applications – enables critical long spans with high strength,
reduced sag and excellent damping
• EHV / UHV (and DC) Voltages – excellent core stability and surface
smoothness enable bundling and decreased corona
• Mountainous Terrain – outstanding strength, toughness and field
experience help installations in difficult and mountainous terrain
• Highly Corrosive Environments – composite core is impervious to
corrosion in salt air and heavy polluted industrial environments
Proven advantages for many project types

ACCC
Standard ACCC uses 310 ksi composite core and 6 ksi Type 1350-O fully
annealed aluminum. Carbon to glass ratio: ~50/50. CTE of core is 1.6 x
10-6/OC. (~60,000 km in service) Cost is ~2 x ACSR
ACCC ULS
ACCC ULS uses 375 ksi composite core and 6 ksi Type 1350-O fully
annealed aluminum. The difference is that the grade of carbon is
slightly higher and the carbon to glass ratio: ~70/30. CTE of core is 0.6 x
10-6/OC (~5,000 km in service). Generally used for long spans or where
heavy ice loads are anticipated. Cost is ~2.5 x ACSR
ACCC AZR
ACCC AZR uses 310 or 375 ksi composite core with one or more
layers of 22 ksi Type AT3 Aluminum Zirconium alloy strands. (See
ASTM Standard B-941 or IEC Standard 62004). This is a new
product developed for use in areas subject to extreme ice and/or
for long spans. Cost is ~2.1 – 2.6 x ACSR
