Introducing the CTC Cable Solution - ACCC
A novel cable design using proven advanced materials
Increases capacity
Improves reliability of a grid system
Improves the safety of any power grid
Core incorporates high-strength carbon and glass fibers with special polymers to create a cable that:
Virtually eliminates thermal sag
ACCC (Aluminum Conductor Composite Core) Conductor

Provides up to 100% increase in ampacity
Has higher conductivity
Significantly reduces elevated temperature sag
Exhibits excellent self-dampening characteristics
Reduced sag and high-strength core allows greater spans (reduces number of structures or reducing height requirements)
Non-metallic core eliminates bi-metallic corrosion
Can replace ACSR without modifying structures due to it’s similar weight and tension properties

ACCC Cable Solutions for the Transmission Grid
Increased power demand
Aging transmission grid
Increasing number of constrained lines
Increased blackout potential
Difficulties in obtaining new pathway approvals
Limited incentives for investment in the grid
Increasing environmental concerns
Regulatory constraints
The ACCC Cable Provides Solutions for the Following:

concentric round conventional TW ACCC/TW eg 795 kcmil eg 959.6 kcmil eg 1020 kcmil
Compared to conventional conductors of the same diameter:
CTC’s ACCC core is lighter and stronger than steel
The ACCC cable has 28% more aluminum for increased conductivity
The ACCC cable uses trapezoidal-shaped aluminum wires and smaller diameter core to increase the kcmil rating
ACCC Design Features
ACCC’s Design is Stronger, Lighter and More Efficient

ACCC – Superior High-Temp Performance
ACCC operated 57° cooler than ACSR with identical current
ACCC cable: 4.5 inches at 183°C
ACSR cable: 60.3 inches at 240°C
Demonstrating Sag AdvantageKinetrics facility, Toronto, Nov. 2003
ACCC Has Very Low Thermal Expansion Coefficient
Testing at temperatures approaching 200 degrees C, shows the cable exhibiting very little sag
