Introduction

• CTC Global is an ACCC conductor
  manufacturing company that was founded to
  develop, certify and deploy advanced technologies
  to improve the efficiency, capacity, reliability
  and resiliency of the electric power grid.
• Our primary product is high-capacity, low-sag
  CTC Global ACCC Conductor solutions.

The globally-patented and trademark-registered
ACCC conductor

• CTC began the development of the ACCC conductor
  in an effort to increase the capacity of
  congested transmission lines that were
  constrained due to thermal sag.
• Essentially, CTC Global recognized the numerous
  advantages of carbon fiber composite materials
  and developed and rigorously tested a
  composite core that is about 50 stronger and 70
  lighter than steel with a coefficient of thermal
  expansion about 90 less than steel it does not
  sag like steel when hot.

About the added aluminum content

• The added aluminum content and quality increase
  the conductors ampacity  or current carrying
  capability  to about twice that of a
  conventional conductor, as well as significantly
  reducing line losses compared to any other
  conductor on the market today.  Line loss
  reductions can range from 25 to 40 or more
  depending on load level. The improved efficiency
  of the ACCC conductor along with its ability to
  carry twice the current of a conventional
  conductor- without excessive sag  offers huge
  advantages.

Increased strength, greatly reduced thermal
sag

• ACCC Conductor, on the other hand, offers
  increased strength (41,200 pounds for Drake
  size), and, more importantly, greatly reduced
  thermal sag. This means that the capacity of an
  existing ACSR line can be doubled by upgrading to
  ACCC without the need to replace or modify
  existing structures.
• Other performance / durability benefits of ACCC
  compared to ACSR or ACSS is that ACCC offers
  greatly improved corrosion resistance as well as
  resistance to fretting failure and cyclic load
  fatigue caused by Aeolian Vibration and thermal
  cycling.
• Finally, and with great significance, the ACCC
  conductors lighter weight composite core allows
  the incorporation of 28 percent more aluminum
  (using compact trapezoidal shaped strands),
  without a weight or diameter penalty. The added
  aluminum content and reduced electrical
  resistance allows the ACCC conductor to reduce
  line losses between 25 and 40 percent compared to
  equally sized ACSR / ACSS conductors.

The lowest cost solution

• Reduced line losses serves to reduce operating
  costs, fuel consumption (and associated GHG /
  CO2 emissions) while also freeing up generation
  capacity that is otherwise wasted.
• When upfront capital costs, maintenance costs and
  life cycle costs are considered, ACCC conductor
  blows away the competition and offers the lowest
  cost solution, by far.
