An innovative company dedicated to developing specialised coatings and semi-autonomous application systems for overhead power lines. Capacity Enhancement • Development of Photonic Coatings for Overhead Power Lines that Increase Capacity by up to 30%. • AssetCool’s SE0-N photonic coating range for overhead transmission and distribution lines that increases capacity by up to 30% via simultaneous solar reflectivity and heat dissipation. • Cooler conductors have lower resistance/lower power losses at a fixed current, or an increased current carrying capacity for a fixed cross-sectional area, up to 30%. CAPACITY-N Robotic System • Direct Application of SE0-N coatings to Overhead Conductors can uprate conductors by 30% without reconductoring. • World leading robotic application technology for overhead lines. Loss Reduction • Application of Photonic Coatings to Conductors can reduce losses by up to 10%, saving over 100MWh/km/year. • Lower conductor temperatures reduce losses by up to 10% due to temperature coefficient of resistance. Substantial performance benefits when deployed on HTLS conductors saving thousands of pounds per kilometre annually. Proven Technology • Over four years of field trial data, thousands of hours of standardised accelerated aging, multiple international research papers and live installation case studies. Manufacturing Excellence • Proven conductor coating apparatus for installation into cable manufacturing facilities with km scale production demonstrated. Associated Manufacturing Engineering services, SOPs, QA/QC.
