28. Lessons Learned
CTC Global ACCC Conductor

29. 1. Pulling sleeve “sock” swivels broke causing conductor to drop (US, Poland,
Columbia) Inspect/test older equipment prior to use
2. Installation grips slipped causing birdcage (Vietnam, US, Russia)
Use correct size grip
3. Conductor damaged at dead-end interface (US, China)
Do not kick dead-end out of compression die, use soap to lubricate dies
4. Conductor damaged at installation grip (Indonesia)
Control loose end while installing dead-end, don’t drop assembly which could cause
excessive bending at Chicago grip
5. Core damaged while being bent around very small reel alignment pulleys (US,
Poland)
Use hydraulic reel brakes to control back tension
Use mid-span sheave wheel to avoid sharp bending when necessary

35. Why Did These Utilities Choose ACCC?
Because, after discovering its technical
merits and evaluating its durability, it
provided the most economical solution
for their specific projects

36. The Value of Line Loss Reduction
Reduced line losses saves money… every year
CTC Global ACCC Conductor

37. The Value of Generation Capacity Savings
Reduced line losses reduces generation capacity investment
It is much less expensive to save energy than it is to produce it
CTC Global ACCC Conductor

38. The Value of Emission Reduction
Reduced line losses reduces fuel consumption
…and associated emissions
Average car in US = 4.7 mt CO2 / scenario 1 = 13,513 cars / scenario 2 = 53,313 cars
CTC Global ACCC Conductor

39. 345 kV Line – Replace ACSR with ACCC
• Increased line capacity by 75% with 625 amp emergency reserve
• Reduced line losses by 30%
• Line loss reduction saves 141,580 MWh / year (=$7.1M @ $50/MWh)
• Emission reductions saves 83,316 Metric Tons CO2 / year
• This equates to removing over 17,500 cars from the road
• Line loss reduction also frees up over 17 MW of generation ($17 M+)
Notes:
Double bundled Drake conductor. Load factor Assumption = 34%
Texas State Average CO2 = 1.297# / kWh. (1 car = 4.75 MT CO2 / year)
Cost of wire ~ $15.4M
Assuming installation cost of $18.6 M – total project cost $34 Million
Equals ~$285,000 per circuit mile (WECC Estimate basis)
