General Cable is proud to present its new groundbreaking E3X Technology at the IEEE PES General Meeting (July 26-30, 2015), which enables utilities to optimize the power grid by adding more capacity and controlling losses. Ultimately, this results in improved sustainability, reliability, and resilience with significant first-cost and long-term operational savings.
The patent-pending E3X Technology is a thin, durable coating applied to the surface of any General Cable TransPowr overhead conductor to increase conductor emissivity and reduce absorptivity, improving heat dissipation and minimizing heat absorption.
TransPowr with E3X Technology drives results — a reduced conductor size for a given ampacity rating, or increased ampacity rating and reduced operating temperature for a given conductor size, improving energy effectiveness and efficiency. And it delivers an accelerated payback period, on average, of less than two years.
Specifically, E3X Technology delivers results — lower project costs by up to 20% by reducing conductor sag or size that optimizes structures, hardware, and labor for new lines. Alternatively, up to 25% lower reconductoring costs are achieved due to increased conductor ampacity, facilitating improved operation within the existing infrastructure without upgrades.
By increasing emissivity and lowering absorptivity of overhead conductors, E3X Technology also reduces conductor line losses up to 25% via lower operating temperature—up to 30%—resulting in significant operational savings for the life of the transmission line. Easy to implement, TransPowr with E3X Technology is a highly adaptive innovation that can be applied without any modification to installation, termination or maintenance practices.
“By increasing power-carrying capacity within an existing infrastructure, E3X Technology improves grid efficiency without compromising on safety and compliance,” said Vijay Mhetar, General Cable’s Senior Vice President of Global Technology. “At the same time, the technology’s ability to increase power-carrying capacity now gives utilities new means to improve sustainability of the more than 90,000 miles of new U.S. Transmission lines expected over the next decade,* including those from renewable energy sources.”
E3X Technology has been tested over several years by a General Cable-directed team of expert development partners; independent test laboratories including Kinectrics and Oak Ridge National Laboratory; and utilities with a focus on energy efficiency and reliability. This groundbreaking, heat-dissipating coating has been tested to the most stringent protocols above and beyond what is required for standard overhead conductor, and it has been evaluated via extensive validation in field trials with installation and test reports available upon request.
“As a global energy industry leader, General Cable developed E3X Technology to meet evolving transmission system requirements and improve economics,” said Jay Lahman, Vice President and General Manager, Electric Utility Products, General Cable. “With a compelling payback of less than two years on average resulting from significant savings from lower project costs, lower reconductoring costs, or lower line losses, TransPowr with E3X Technology is a win-win for utilities, customers and the environment alike.”
