Black Hills Power Completes ACCC Installation in South Dakota


With the help of the Schulte Power Line Construction Company, Black Hills Power Corporation, an investor owned utility serving nearly 70,000 customers in 20 different communities throughout western South Dakota, northern Wyoming and southeastern Montana successfully completed the installation of ACCC Hawk size conductor to increase the capacity of a 69 kV line in Spearfish, South Dakota. Bill Percy and Ismael Dones, CTC's installation supervisors were on the scene to provide support. ACCC conductor was selected for this project as it could be used to increase capacity without the need to add new structures or reinforce existing structures. The finished conductor was manufactured by Lamifil, one of CTC Global's 19 certified and licensed manufacturing partners.

New 'ULS' ACCC Conductor Developed for Heavy Ice & Long Span Applications


To combat extreme ice load events and very long spans, CTC Global recently introduced a number of new conductor designs that use a higher strength, higher modulus composite core.  These new conductor designs are known as ACCC ULS.  The tensile strength of the ULS core is 375 ksi which  is greater than the normal ACCC conductor's 315 ksi, both of which are greater than high strength 285 ksi steel.  The composite cores are also about 70 percent lighter than steel which further reduces conductor sag and stress on the supporting structures.

Why Over 100 International Utilities Have Selected ACCC

  • High Capacity
  • Low Sag
  • High Strength
  • Fatigue Resistant
  • Corrosion Resistant
  • Excellent Self Damping
  • Easy to Install
  • Great for Long Spans
  • Very Tough
  • Extensively Proven
  • Excellent for N-1 Conditions
  • Lower Line Losses


The ACCC Conductor's added aluminum content (without a weight or diameter penalty) allows it to run cooler under any load condition which translates into reduced line losses. Reduced line losses can save fuel, emissions and generation capacity.


The Bottom Line:

In more than 300 cases, the ACCC conductor has offered over 100 utilities the best economic solution for their particular project. 


Free Design Software
CTC Global created CCP to help system planners and engineers compare the ampacity, line losses, thermal and ice load sag, and economic aspects of nearly any conductor type and size, so the numerous advantages of the ACCC� conductor can be fully realized. The user simply selects the conductor types and sizes from drop down menus and enters the appropriate values & assumptions highlighted in the yellow boxes. The program is fully functional and uses standard industry formulas (such as IEEE 738-2006). Outputs are readily comparable to Sag10�, PLS CADD™ and other similar programs.
