Three Excellent Reconductoring Case Studies Published In T&D World Magazine
Reconductoring existing transmission lines with modern high-capacity, low-sag ACCC® Conductor offers tremendous advantages compared to rebuilding existing transmission lines using conventional conductors. Increasing capacity to support load growth and N-1 conditions; Reusing existing structures to save time and money; And freeing-up human resources and equipment are just a few examples. If you are interested, please check out these outstanding examples recently published in T&D World Magazine:
"The use of modern power line conductors with carbon-fiber cores has improved efficiency in power delivery." T&D World Link
"SSEN Transmission is using modern technology to extend the asset life of its existing tower fleet and future proof the network using the existing towers and modern conductors." T&D World Link
"When does specialized composite conductor make sense for a conductor upgrade project?" T&D World Link

Power Grid Company of Bangladesh is Helping Support one of Asia's Fastest growing Economies
To accommodate continued growth and prepare for an amazing future, the Power Grid Company of Bangladesh “PGCB” is working hard to modernize their electric power grid which is expected to deliver 60 GW of electricity within the next two decades. Policy makers in Bangladesh have taken a pragmatic decision to push for a robust and sustainable future, by selecting climate friendly and high capacity ACCC® Conductors.
Bringing reliable and clean electricity to the people of Bangladesh is critical to growing the economy, improving the standard of living, and reducing environmental impact to combat climate change.
To upgrade and expand their transmission network, PGCB selected the high-capacity, energy-efficient and highly-proven ACCC® Conductor technology. While ~40 ACCC® Conductor installations have been, or are in the process of being completed in Bangladesh, more than 1,000 ACCC® Projects have been completed, worldwide.
The ACCC® Conductor not only doubles the capacity of the existing transmission system, it also reduces electrical power losses by approximately 25-40 percent compared to other conventional all-aluminum and steel reinforced conductor types.
Reduced line losses reduces fuel consumption and associated greenhouse gas emissions, and also reduces the need to build additional generation assets. As an FYI, the ACCC® Conductor is produced by 35 authorized and licensed manufacturing partners, worldwide. Please scroll to the bottom of this newsletter or CLICK HERE to learn more.
A good example of the successful use of the ACCC® Conductor in Bangladesh is the 160 circuit kilometer Patuakhali (Payra) to Gopalganj 400 kV transmission line. This new transmission line delivers power from Payra Power plant to the new 132/400 kV Gopalganj substation, a major power hub. Please see video below.
After viewing the project video, Mr. Yeakub Elahi Chowdhury, Executive Director (P+D) PGCB commented: “The project mentioned in the video is quite important but represents only a fraction of the projects completed by PGCB using ACCC® Conductor. For example, one of the featured uses of the ACCC® Conductor is the transmission of power from the Rooppur Nuclear Power Plant. We are using this advanced conductor on our most critical projects in Bangladesh.”

Important Policy Update for Electric Power Utilities in the United States
The “Infrastructure Investment and Jobs Act” (“the ACT”), also referred to as the Bipartisan Infrastructure Bill, was recently signed into law. Several of the provisions in the ACT opened significant opportunities for using ACCC® Conductor to meet the ACT’s objectives. In three of the ACT’s sections, advanced conductors were explicitly called out in the law.
- In Section 40101, Preventing Outages and Enhancing the resilience of the Electric Grid, Grant recipients can use the money to reconductor power lines with low-sag, advanced conductors.
- In Section 40106, Transmission Facilitation Program, the Secretary of Energy is to give priority in their loan and facilitation program to projects that use technology that enhances capacity, efficiency, resilience, or reliability of an electric power transmission system including reconductoring of an existing electric transmission line with advanced conductor.
- In Section 40107, Deployment of Technologies to Enhance Grid Flexibility, the Grant matching funds can be used by transmission owners and developers to purchase and installation advanced transmission technologies such as advanced conductors.
While ACCC® Conductor has a role to play in other aspects of the ACT, it explicitly can be used preferentially when securing grants and funding under these ACT programs.

ACCC® ULS Conductor Offers Added Strength and Reduced Sag
First deployed on a 1.4 kilometer lake crossing in Africa in 2013, The ACCC® ULS Conductor offers greater strength, a lower coefficient of thermal expansion and higher modulus of elasticity than the standard ACCC Conductor core. The added strength and lighter weight can enable longer spans and the higher modulus and increased stiffness reduces sag and blow out during high wind conditions. Improved stiffness can also reduce sag under heavy ice load conditions.
Dozens of engineers have specified ACCC® ULS Conductor for projects, worldwide, and the ULS version of the ACCC® Conductor has served our clients well. The ACCC® ULS Conductor is available in many sizes and offers transmission engineers added design flexibility.
The ACCC® ULS Conductor can be ordered with Type 1350-O fully annealed aluminum or as an AZR version with Aluminum-Zirconium thermal resistant alloy for even higher overall conductor strength.

ACCC AZR Conductor – Expanding the Capabilities of the ACCC® Conductor Using Aluminum Zirconium Alloy to Combat Extreme Ice Loads
ACCC® AZR Conductor uses either the standard 310 ksi core or the higher strength 375 ksi core that is then wrapped with one or more layers of a high strength, thermal resistant aluminum-zirconium alloy. While conventional ACCC Conductors typically use fully annealed aluminum to maximize conductivity, the ACCC AZR Conductor offers nearly the same efficiency, but far greater overall strength. The added strength and increased tensile modulus mitigates conductor sag under heavy wind or ice loads, or very long spans. To learn more visit www.ctcglobal.com
