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.

Objective 

• The ACCC conductor has become the dominate
  technology for transmission and sub-transmission
  projects where efficiency, capacity, reliability a
  nd resiliency are paramount design objectives. 
• The ACCC conductors hybrid carbon fiber
  composite core also makes it ideally suited for
  long span applications for a number of important
  reasons.

 ACCC conductor Composite Core 

• The strength to weight ratio of the ACCC
  conductor composite core is approximately five to
  seven times greater than a steel core.
• The standard ACCC composite core is rated at 310
  ksi, while the high-strength version (known as
  ULS) is rated at 375 ksi.

ACCC conductor Composite Core 

• The weight of the ACCC composite core is 70
  percent less than steel.
• Furthermore, steel core strands are typically
  helically wound around a central core strand.
  Within the diameter of the overall steel core,
  approximately 25 percent of the area is void. 
• The ACCC composite core consists of hundreds of
  thousands of structural fibers bound together
  with a high-performance epoxy matrix without any
  voids. 
• The lack of voids not only enhances core
  strength, it also prevents Aeolian Vibration from
  causing fretting fatigue, microfracture
  propagation and stress fatigue failure where the
  round strands typically rub against themselves,
  especially at higher tensions in areas prone to
  wind.

ACCC Conductor is further improved

• ACCC conductor, the resistance to Aeolian
  Vibration is further improved by the fact that
  the ACCC conductor uses compact, trapezoidal
  shaped aluminum strands. 
• The ability to dissipate vibration more
  efficiently is a highly sought attribute for
  conductors that are deployed on long spans where
  tension is much higher and where predominate
  winds at higher elevations above ground or water
  generate Aeolian Vibration.

• The lighter weight and greater strength of the
  ACCC conductor can contribute significantly to
  reducing structural costs and tower height.
  Additionally, the ACCC conductors composite core
  offers a very low coefficient of thermal
  expansion so, under heavy electrical loads, the
  core does not elongate causing additional
  conductor sag.
