TransPowr® with E3X® Technology is the only universal heat-dissipating technology for overhead conductors that optimizes the power grid by adding more capacity and controlling losses, ultimately resulting in improved sustainability, reliability and resilience with significant first-cost and long-term operational savings!

By increasing conductor emissivity (improving heat dissipation) and reducing absorptivity (minimizing heat absorption), groundbreaking 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.
