Factory Applied Photonic Coating
SE01 PHOTONIC COATING FOR OVERHEAD POWER LINES
Simultaneous Solar Reflectivity and Thermal Emissivity: Passive Radiative Cooling of Overhead Lines
The thermal rating of overhead power lines refers to the maximum amount of electrical current that can flow through the lines without exceeding sag clearances. Our coating applied at the factory, reduces solar absorption and increases emissivity.
This passively manages the temperature of the conductor by rejecting solar radiation and emitting heat directly into space. This passively lowers the temperature of conductors by up to 25%, offering a 30% increase in capacity or a 10% reduction in resistance.
SE01
10% Power Loss Reduction on HTLS Conductors
Innovating Today for Tomorrow’s Energy Needs
THE PROBLEM
Utilities need to increase capacity. Reconductoring is a significant component of the energy transition and many utilities are opting for High Temperature Low Sag (HTLS) conductors. HTLS conductors are optimised to operate continuously at elevated temperatures with up to 100% increase in current carrying capacity on the same towers and right of way. Higher temperature conductors have higher resistance and higher power loss. Cooler HTLS conductors will provide the additional ampacity required, with lowest total cost of ownership (TCO) and optimal loss reduction.
THE SOLUTION
SE01, developed by AssetCool, is a spectrally selective coating that optimises the surface to maximally reflect sunlight and dissipate heat. It reflects over 80% of solar radiation and optimises heat dissipation, lowering conductor temperatures by up to 25%, reducing resistance, and cutting transmission losses by up to 10%. Alternatively it boosts current carrying capacity within the same cross sectional area by up to 30%.
Designed purely from inorganic materials, with multiple years of field trial data, multiple decades equivalent of accelerated aging, SE01 has been demonstrated to provide continuous performance over time.
