Composite Technology Wins Third ACCC(R) Conductor Order in South Africa
Monday, Aug 16, 2010
Composite Technology Corporation (CTC) (The exponential demand growth and resulting strain on the electrical grid in the Johannesburg region of South Africa has led City Power Johannesburg to take steps to modernize its grid quickly and efficiently. Quanta Services selected CTC Cable's ACCC® Conductor to enable City Power Johannesburg to increase capacity over 100% while reducing both line losses and thermal sag on existing structures. Quanta Services use its patented propriety LineMaster™ robotic-arm and energized technique of replacing the conductor while the line is energized, so there is no interruption of electrical service or rerouting of the load.
This order follows last year's order for 210 kilometers and another emergency replacement order in June 2010 for 23 kilometers and demonstrates the confidence Quanta Services and City Power Johannesburg have in ACCC® conductor's superior composite core conductor technology as the best solution for the severely constrained electrical grid in Johannesburg. CTC Cable is the major global supplier of composite core conductor, with about 9,000 kilometers of ACCC® conductor commercially deployed at over 140 installations.
City Power in Johannesburg contracted Quanta through a local South African partner, Edison Jehamo Power (EJP), to uprate the existing 88 kV network around Johannesburg, using Quanta proprietary LineMaster™ energized robotic arm technology. The Quanta Team selected high-temperature composite core conductors for the replacement wire because it can operate at 200 degrees C under peak loading conditions. The ACCC® conductor performs well both during energized installation and under operation.
In this first phase of the project, 12 km of four double circuit 88 kV lines had to be uprated through a congested Right-of-Way (ROW) with limited access in the urban areas of Johannesburg.
"We are pleased with this new order for our ACCC® conductor from Quanta Services. The combination of our patented higher capacity conductor technology with Quanta's patented installation technique significantly improves the capacity and reliability of City Power Johannesburg's system without interrupting service to their customers," stated Benton Wilcoxon, Chief Executive Officer of Composite Technology Corporation.
About CTC:Composite Technology Corporation's patented ACCC® conductor technology enables superior performance of high voltage transmission and distribution electrical grids. ACCC® conductors use CTC's proven carbon fiber core which is produced by its subsidiary, CTC Cable Corporation, at its Irvine, California headquarters and delivered to qualified conductor manufacturers who produce and distribute ACCC® conductors to operators of electrical grids worldwide. CTC's conductor technology significantly reduces thermal line sag and can replace similar diameter and weight traditional conductors with its higher capacity and more energy efficient ACCC® conductor. It is an ideal conductor for both upgrading existing power lines as well as building new lines since the technology allows for the reduction of the number of support structures and/or a reduction of their height. Since its commercial introduction in 2005, nearly 9,000 kilometers of ACCC® conductor have been installed in all environmental and operating conditions, including severe heat and ice environments, long span applications and high capacity corridors for the modern grid. ACCC® is a registered trademark of CTC Cable Corporation.
