ACCC Conductor Installation Completed in Odessa, Texas 


ACCC Installed to Increase Line Capacity 




To increase the capacity of an existing transmission line linking two substations in the downtown area of Odessa, Texas, ONCOR selected McCurley Enterprises Inc. and Power Secure Corporation to install approximately 36 km of ACCC conductor. Following a three hour classroom training session, the linemen began the installation. More than a dozen man-lifts were placed in position to protect roadways and rail crossings in the highly populated downtown area allowing the existing wire to be used to pull in the new ACCC conductor. 


Once the first three conductor phases were pulled in, Bill Percy, CTC Global's Field Supervisor, assisted the linemen in making the first three "soft-side" dead-ends on the ground. This was actually the first time any of the linemen had installed the specially designed ACCC dead-end assemblies. The classroom training helped the linemen learn correct procedures which allowed the installation to proceeded quickly without issue.


After the first three dead-ends were lifted into position and connected to insulators, and the first section of the line tensioned, "hard-side" dead-ends were installed in the air using bucket trucks. The project was completed in approximately five weeks.


After the project was completed, Eric Trammell, McCurley's Field Supervisor, commented "the ACCC conductor was the easiest conductor he had ever sagged." He also commented how "tough" he found the composite core to be. Prior to the project's start Eric and some of the linemen did an unofficial bend test and were very surprised to find out just how much bending the composite core could actually handle without damage. In Eric's words "they were quite impressed."


This project represents the 261st ACCC installation completed to date. Currently there are 12 other ACCC installations 'in the works' or underway, including AEP's 240 circuit mile (live-line) 345 kV reconductor project in southern Texas. This single project (AEP's 9th ACCC installation) will utilize over 1,440 miles (2,300 km) of ACCC conductor.

Value of Line Loss Reductions


 A "Must Read" for Everyone Involved in T&D



Earlier this year, The Brattle Group submitted a peer reviewed report  "The Benefits of Electric Transmission: Identifying and Analyzing the Value of Investments" to "WIRES" (Working group for Investment in Reliable and Economic electric Systems)*


WIRES commissioned the report in an effort to help develop, among other things, more equitable means of evaluating the numerous ways investment in transmission projects might benefit stakeholders, ratepayers and society in-general. The report catalogues a number of potential benefits that could (or should) be considered by planners and policymakers. 


CTC Global applauds the thoughtful compilation of facts, as many of them underscore the important role advanced technologies such as the ACCC conductor can play in improving the efficiency, capacity and reliability of the grid.


While the report doesn't recommend any technology or solution in particular, its discussions regarding the substantial impact reductions in line losses and grid congestion can have, are remarkable and quite accurate.


As CTC Global has also pointed out in the past, line loss reductions can not only conserve fuel (and in some cases reduce emissions), they can also reduce generation capacity requirements, improve grid reliability and improve project economics. These are just a few examples of how the ACCC conductor and other emerging technologies can benefit society.


While CTC Global initially developed the ACCC conductor to alleviate congested transmission lines by leveraging aerospace technology, the ACCC conductor's lower resistance
compared to other conductors of the same diameter and weight also serves to reduce line losses by 25 to 40% or more under equal load conditions. The advantages provided by the ACCC conductor are very much aligned with several key elements discussed in the report.

Conductor Selection Software 



Responding to an ever-increasing demand to help select the most appropriate size of the highest performing ACCC conductor available, CTC Global has developed a new software program, CCP.


The program is available at no charge to utility planners, transmission engineers and others involved in conductor selection, project engineering and project economics. Using the design parameters associated with your specific project, CCP can calculate and compare ampacity, sag, tension, line losses, and the economics associated with the reduction in thermal sag and line losses the ACCC conductor offers compared to any other conductor of the same diameter and weight.
