Recently, the approval of a key national research and development program has attracted widespread attention. The project, led by Zhejiang University, is undertaking… The project “Research and Development of Self‑Cooling, Capacity‑Enhancing Coatings for High‑Voltage Transmission Lines and Their Ultra‑Thin Self‑Healing Coatings” has been officially approved. This project focuses on addressing the numerous issues caused by heat accumulation in outdoor‑operating high‑voltage transmission lines and other power‑equipment, with the aim of developing self‑cooling coating materials for high‑voltage transmission lines based on the principle of passive radiative cooling. This announcement has once again placed radiative cooling technology at the forefront of the energy sector, and it is closely related to our radiative cooling testing system.

Challenges Facing High-Voltage Power Transmission and Opportunities Presented by Radiative Cooling Technology

High-voltage transmission, a cornerstone of the national energy strategy, is of paramount importance. However, insufficient current-carrying capacity and heat‑accumulation issues have long plagued the industry. Applying radiative cooling self‑cooling coatings has emerged as an effective solution, significantly mitigating thermal‑cycle fatigue in conductors, extending their service life, and enhancing the stability and reliability of power systems.

The project approved this time addresses challenges associated with high-voltage transmission conductors and conducts research from multiple perspectives. It involves designing microstructures with high scattering efficiency and thermal emissivity tailored to the unique curved surfaces of high-voltage conductors; developing functional elastomers and metal-oxide cooling coatings to enhance cooling performance, durability, and environmental adaptability; establishing kilogram-scale production technologies for these cooling materials along with compatible unmanned continuous coating processes; and conducting field‑scale cooling tests across diverse climatic zones to evaluate both the actual capacity‑enhancing effects and the self‑cooling characteristics of high-voltage conductors under various operating conditions.

How our radiative cooling test system works

Against this broad backdrop, our radiative cooling test system plays a crucial role. Whether it is developing new radiative cooling coating materials or evaluating their performance under various environmental conditions, precise testing equipment is indispensable.

Our radiative cooling test system boasts a range of advanced features. It can simulate diverse environmental conditions—such as temperature, humidity, and light intensity—which is essential for evaluating the performance of radiative cooling materials across different climatic zones. Just as the aforementioned project requires on-site cooling tests in various climate regions, our system enables preliminary simulation-based testing in the laboratory, providing valuable data and technical support for subsequent field trials and significantly reducing both time and costs.

In testing the reflectance and emissivity of radiative cooling materials, our system is equipped with high-precision measurement instruments, capable of accurately measuring the material’s properties at… The reflectance in the visible and near-infrared spectral range (0.3–2.5 μm), together with the emissivity in the atmospheric radiation window (8–13 μm), ensures the accuracy and reliability of the data. This is crucial for determining whether a material meets the project’s stringent performance criteria.

Our system also excels in evaluating the cooling amplitude and cooling power of radiative cooling materials. Through precise temperature measurements and data analysis, it can accurately determine the material’s daytime cooling amplitude and cooling power, providing researchers with clear, actionable data to optimize material performance and meet the project’s requirements: “daytime cooling amplitude > 10% and cooling power > 150 W/m².”

Product Advantages and Application Prospects

Compared with other similar products on the market, our radiative cooling test system offers significant advantages. The system boasts exceptional stability; rigorous testing and real-world applications have demonstrated that it can maintain data accuracy over extended operating periods, without introducing measurement biases caused by equipment malfunctions or performance fluctuations. This is of critical importance for research projects and manufacturing enterprises that require long-term, continuous monitoring of the performance of radiative cooling materials.

Ease of operation is another key strength of our product. The system features a user-friendly design and an intelligent interface, enabling even first-time users to quickly master its operation. This significantly boosts testing efficiency and minimizes errors that might arise from unfamiliarity with the equipment.

In terms of application prospects, in addition to the high-voltage transmission sector, our radiative cooling test system can also be widely deployed across multiple industries, including construction, automotive, and electronics.

The approval of this National Key R&D Program project heralds new opportunities for the advancement of radiative cooling technology. We look forward to collaborating with more research institutions and enterprises to jointly drive the development of radiative cooling, contribute to addressing pressing challenges in the energy sector, and provide more efficient, environmentally friendly technological solutions to support the growth of various industries.
