Composite Technology Corporation INNOVATIVE CONDUCTOR SOLUTIONS FOR POWER TRANSMISSION AND DISTRIBUTION SYSTEMS

Introducing the CTC Cable Solution - ACCC

ACCC (Aluminum Conductor Composite Core) Conductor 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:

The CTC Cable Solution - ACCC

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

The ACCC Cable Provides Solutions for the Following:

        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 Copyright 2005 Composite Technology Corporation.

ACCC Design Features

ACCC’s Design is Stronger, Lighter and More Efficient 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 Copyright 2005 Composite Technology Corporation.

ACCC – Superior High-Temp Performance

ACCC Has Very Low Thermal Expansion Coefficient

 Testing at temperatures approaching 200 degrees C, shows the cable exhibiting very little sag

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 Advantage
