Photovoltaic cable tray is a specialized cable laying supporting product designed specifically for new energy photovoltaic projects. It is designed for special working conditions such as outdoor exposure, long-term sun exposure, and variable temperature differences in photovoltaic power stations. It is widely used in various new energy projects such as ground centralized photovoltaic power stations, industrial and commercial rooftop photovoltaics, fishery photovoltaic complementarity, and mountain photovoltaics, and is also suitable for new energy infrastructure procurement projects at home and abroad. The product can be made of various mainstream materials such as galvanized, plastic sprayed, aluminum alloy and macromolecule. After targeted anti ultraviolet, anti-aging and anti-corrosion processes, it can effectively resist outdoor strong light exposure, rain wash, wind sand erosion, coastal salt spray and other environmental impacts, slow down the aging and corrosion process of the base material, and can adapt to the outdoor complex climate environment for a long time. The product structure conforms to the characteristics of photovoltaic cable laying, with good ventilation and heat dissipation performance, which can timely dissipate the heat generated during the operation of photovoltaic cable power generation, maintain stable operation of the line, and adapt to the long-term uninterrupted operation needs of photovoltaic systems. The overall structure is stable, with good wind and pressure resistance, and can adapt to special installation scenarios such as roof tilting and outdoor overhead. It fully fits the operation cycle of photovoltaic power plants for about 25 years, with low daily operation and maintenance pressure. It is a commonly used supporting product for new energy photovoltaic engineering wiring.
