Learn how Important is the Transmission Line Efficiency, Capacity and Reliability. Learn how ACCC Conductor improves the project profitability. How to Improve the Economic Viability of Renewable Resources Leveraging modern conductors such as ACCC can improve the economic viability of renewable resources projects and enable the power grid to handle added electrical current.
Renewable energy resources are often located miles away from local demand centers. Wind farms,... read more NARUC Passes Resolution Supporting Advanced Electric Transmission Technology The National Association of Regulatory Utility Commissioners (NARUC) passed an important amendment just under a year ago that underscores the importance of using high performance and energy efficient conductors such as ACCC. Increase the capacity with CTC Global’s ACCC Conductor. CTC Global’s ACCC® conductor was developed to increase capacity and carry twice the current of conventional all-aluminum and steel reinforced conductors.
While classic AAC, AAAC and ACSR conductors were limited to operating temperatures of ~90°C, other high temperature conductors such as ACSS, Invar and GAP were also designed to carry twice the current as well. Double the transmission capacity with CTC Global’s ACCC conductor. The CTC Global ACCC conductor utilizes a hybrid carbon and glass fiber core embedded in a high-performance thermoset epoxy matrix.
The central carbon fiber core consists of tens of thousands of high-strength, high-modulus unidirectional carbon fibers that are surrounded by a protective layer of glass fibers. The outer glass fibers improve toughness and flexibility while also providing a galvanic barrier to prevent corrosion with the conductive aluminum strands. The lighter weight allows the CTC Global ACCC conductor – of any size – to utilize ~28% more aluminum without a weight or diameter penalty.
The compact trapezoidal strands and smooth surface composite core work in unison to dissipate wind-induced vibration. While the aluminum strands are fully annealed, offering the highest degree of conductivity for any aluminum available today, the composite core offers a coefficient of thermal expansion about ten times less than steel. CTC Global History – Learn more about it. Our company was founded to develop, certify and deploy advanced technologies that electric utilities could use to improve the efficiency, capacity, reliability and resiliency of the electric power grid, worldwide. To date we have more than 450 projects completed in more than 40 countries. Our primary product is the high-capacity, low-sag (“HCLS / HTLS”) CTC Global ACCC Conductor. ACCC® is a registered trademark of CTC Global. CTC Global is a privately held Delaware Corporation headquartered in Irvine, California midway between Los Angeles and San Diego. We are located about one mile east of the Orange County John Wayne (SNA) airport, less than ten miles from the Pacific Ocean and Newport Beach.
CTC Global’s 110,000 square foot facility in Irvine, California houses its corporate offices, business development team managers, product engineering and R&D staff, application engineers, procurement and production teams and quality assurance staff. CTC Global – Technology. The CTC Global Technology that we use, develops, tests, and commercializes the ACCC® conductor and ancillary hardware components that improves the efficiency, capacity, reliability and resiliency of the electric power grid. CTC Global’s ACCC Conductor – Learn how it improves the grid efficiency. CTC Global provide conductor efficiency that can reduce CO2 emission. In the world of commodity transmission conductors, conductor efficiency is generally not considered to be high on the priority list. Conductor selection is generally based on load considerations. But times are changing. Looking back a few years, consider the substantial investments that were made to improve the efficiency of generators to reduce fuel consumption and/or help improve the economic viability of competing generation technologies such as solar and wind.
Improved transformer technologies, while slightly more expensive, were also easy to justify – as they offered reduced lifecycle costs and improved efficiency. On the demand side, consider that billions of dollars have been spent to improve the efficiency of demand side appliances such as refrigerators, air conditioning units and even light bulbs.
Achieve emission reduction goals cost-effectively with CTC Global’s ACCC Conductor. Concerns about climate change continue to shape corporate and regulatory policy.
The use of high-capacity, high-efficiency ACCC conductors can help you cost-effectively achieve your organization’s emission reduction goals CTC Global’s high-capacity, high-efficiency ACCC conductors offers one of the most cost-effective means of reducing fuel consumption and associated emissions, while also increasing grid capacity to support the deployment of more clean renewable energy.
Let’s consider an example based on a recently completed American Electric Power project in Texas. Looking at a 100 mile section of 345 kV line designed to carry 3,000 amps with a load factor of 62%, the use of CTC Global’s Drake size (double bundled) ACCC conductor would reduce line losses by 30% compared to an equally sized ACSR Drake conductor.
This translates into a savings of 300,000 MWh per year. For comparison, consider the energy savings offered by a 100 watt equivalent LED light bulb replacement. CTC Global Software Helps Utilities Improve the Efficiency, Capacity and Reliability of the Grid - CTC Global. Challenged by an increase in demand for affordable electricity, many system planners and transmission engineers are being asked to find economical ways to reduce grid congestion and improve grid reliability. In many cases, grid congestion costs the utilities and the customers they serve tens to hundreds of millions of dollars annually. Restrictions on new line permitting and advances in conductor and related technologies have changed the options available to planners and engineers trying to solve these problems; until the introduction of CTC Global Software, however, there have been limited design tools available that can help illustrate the differences between multiple conductor solutions.
Grid congestion is often described as a condition where existing lines are no longer capable of importing power from less expensive and often remote sources of generation, forcing utilities to develop and use more expensive, local sources of generation.
