APAR Completes Several Important Projects in India 
 
Apar Industries Ltd, one of CTC Global's two dozen authorized ACCC conductor manufacturing partners completed several projects in India during the last three months.
 
The projects include PTCUL's Roorkee to Mangalore (double circuit line) and Roorkee to Laksar (single circuit) 132 kV projects (11.9 and 27.2 km, respectively) in Uttarakhand, India; MSETCL's Khapri to Besa and Besa to Pardi 132 kV lines (13.8 km) in Maharashtra, India.
 
Apar provided ACCC Copenhagen conductor to replace existing ACSR Wolf and ACSR Panther size conductors for the Roorkee to Mangalore and Roorkee to Laksar lines, and ACCC Casablanca conductor for the MSETCL projects to replace ACSR Panther.
 
Each project carried its own unique challenges including aged structures, dense population areas, heavy industrial zones, agricultural regions and wetlands, and several highway, railway and canal crossings. The projects were also completed under very cold and dense fog conditions. The crews completed each project with great success and received accolades from their utility customers.

Kahramaa Completes 1st Circuit of Second ACCC Project in Qatar  
 
General Electricity and Water Corporation of Qatar (Kahramaa) was established in 2000 to regulate and maintain the supply of water and electricity in a country with over 4,000 km of aging overhead powerlines.
 
A tremendous surge in the demand for reliable energy has emerged in recent years.Due to this increased demand, construction of a $2.75 Billion, 2,520 Megawatt Power Plant "Umm al Houl" has recently begun. Additionally, Kahramaa has teamed up with Qatar Petroleum, who have agreed to help fund the development of numerous large solar power plants in Qatar over the next few years. These projects constitute a large portion of Qatar National Vision 2030, a program designed to heavily promote the country's economic and social development. 
 
In January, TEEMS India - led by ACCC Master Installer R. Vasanthakumar - completed work on the 1st circuit of Kahramaa's second ACCC reconductor project, located in North-Eastern Doha, Qatar. The project consists of upgrading the existing 132 kV ACSR double circuit line with state-of-the-art ACCC conductor, manufactured by Midal Cables of Bahrain. Hardware for the project was provided by Mosdorfer. The 1st circuit was energized earlier this month following substation upgrades. The second circuit upgrade has begun.
 
With over 60,000 km of ACCC installed to date, ACCC continues to be the chosen transmission solution globally because of its unwavering performance especially in places with extremely high ambient temperatures and highly corrosive environments such as those found in Qatar a country nearly surrounded by Persian Gulf salt water.
 
CTC Global's relationship with Kahramaa began in 2010 when the ACCC conductor passed rigorous testing and evaluation, leading to "Type Certification." In 2011 - 2012, Kahramaa used ACCC conductor to upgrade existing 132 kV circuits to increase capacity from 125 MVA to 260 MVA with outstanding success. CTC Global looks forward to a continued effort in strengthening Qatar's electrical grid, and helping Kahramaa reaching the goals outlined within the "Qatar National Vision 2030" program.
 
FERC Chairman McIntyre discusses Grid Resiliency at NARUC Meeting
CTC Global Participates at NARUC Winter Policy Summit

CTC Global sponsored and exhibited at the 2018 National Association of Regulatory Utility Commissioners (NARUC) Winter Policy Summit in Washington DC, February 11-14. 

Electric system resilience was the topic of several panels.  ACCC, as a high performance conductor, delivers more capacity and higher efficiency than the ACSR conductor it replaces.  Additionally, the composite core in the ACCC conductor is smaller, lighter and much stronger than the ACSR core it replaces. The stronger composite core has delivered increased resilience in real world conditions. 

In one example, a U.S. utility had its ACCC conductor hit by a EF-4/5 tornado which stripped the outer aluminum conductor strands from the inner composite core.  Fortunately the very strong ACCC composite core did not break which enabled very rapid repair.  ACCC contributes increased resilience to the electric grid.

Why High-Capacity, Low-Sag ACCC Conductor Offers a Better Solution Compared to ACSS Conductor

The introduction of ACSS (Aluminum Conductor Steel Supported) conductor offered increased capacity over ACSR due to its ability to operate at temperatures as high as 250°C. While this attribute enabled a substantial increase in capacity, the reality is that ACSS conductor simply sagged more as if it was an ACSR conductor under overload conditions.
 
The ACCC conductor, introduced in 2004, was a giant leap forward in terms of mitigating thermal sag, as its high-strength, light-weight and very low coefficient-of-thermal-expansion mitigated the problem of thermal sag.
 
Additionally, because the composite core is so much lighter than steel, the ACCC conductor utilizes ~28% more aluminum. The added aluminum not only helps it carry more current, its lower electrical resistance also serves to reduce line losses under any load condition.
 
Reduced line losses not only reduces fuel consumption and associated emissions, it also frees-up generation capacity that is otherwise wasted.

ACCC® Conductor Receives 3rd Party Certification for Energy Efficiency and CO2 Emission Reduction Credits 

CTC Global ACCC conductor is the first electric transmission conductor in history to earn SCS certification for CO2 emission reductions resulting from improved energy efficiency. 
 
SCS Global Services (SCS) verified that ACCC conductor reduces CO2 emissions associated with transmission line losses by 27 to 31 percent under certain design conditions compared to conventional steel reinforced ACSR conductors, the 100-year old technology currently used in most electric transmission and distribution power lines.
