2. Introduction CTC Global is a ACCC conductor manufacturing company that was founded to develop, certify and deploy advanced technologies to improve the efficiency, capacity, reliability and resiliency of the electric power grid. Our primary product is high-capacity, low-sag CTC Global ACCC Conductor solutions. www.ctcglobal.com

3. TenneTNetherlands Selects ACCC® AZR™ Conductor in Netherlands Several months ago, CTC Global introduced the ACCCAZR™ Conductorwhich uses an aluminum zirconium alloy to augment overall conductor strength and modulus to help fight extreme ice and wind loads. TenneTNetherlands selected ACCC AZR™ for the new product’s initial deployment in Europe, for their reconductor project in the Netherlands. www.ctcglobal.com

4. TenneT faced a particular challenge when upgrading the double circuit line between Groningen and Delfzijl. The total route length of 28.2 km over flat terrain covering 89 towers is subject to high wind and potentially extreme ice loads. TenneT selected ACCC Warsaw size ACCC AZR Conductor manufactured by Midal Cables which satisfied their capacity increase requirements from 760 amps to 1323 amps. An additional 2.1 km spur line tying in the Stadskanal substation also upgraded from 500 amps to 777 amps at the same time. “This design adds significant capability and cost-effectiveness to CTC Global’s proven ULS (Ultra-Low-Sag) core variants already deployed in Northern Europe, particularly for areas where high wind and ice loads can be expected” stated Dr. Eric Bosze, CTC Global’s Director of Conductor Materials Research. www.ctcglobal.com

5. ETESA Completes 2nd 230 kV ACCC Conductor Installation in Panama With the support of EPC firm Elecnor Group, ETESA completed the installation of 85.23 circuit kilometers of 714 kcmil Dove size ACCC Conductor to replace forty-six year old 750 kcmil ACAR conductor on their Mata de Nance to Veladero line near David City, Panama. www.ctcglobal.com

6. The project included a 38 kilometer section of suspension towers with no dead-end structures, requiring a strategic stringing plan provided by CTC Global’s Master Installers, Sergio Rojas and Ismael Dones. Replacing the ACAR conductor with ACCC Conductor allowed ETESA to increase line capacity from 230 MVA to 480 MVA. ACCC Conductor provided for the project was produced by Viakon. The average span length was 350 meters, but greater in some areas where the conductor traversed river and mountain crossings. Forjasul provided hardware and Tesmec tensioners were used. www.ctcglobal.com

7. National Grid Corporation Completes ACCC Conductor Upgrade in Vietnam Earlier this month, National Grid Corporation (NGC) Vietnam completed their 110 kV Viet Tri – Bai Bang line upgrade (ACCC Conductor Upgrade) to increase line capacity. NGC selected 725 kcmil (367.4 mm^2) Amsterdam size ACCC Conductor to replace existing 240/32 ACSR conductor so they could reuse their existing steel lattice structures without modification.  www.ctcglobal.com
