In recent years, under the support and guidance of relevant national policies, the solar photovoltaic power generation industry has developed rapidly, and the installed capacity of solar power plants has increased year by year. However, due to the relative lag in the research and development and marketing of domestic photovoltaic cables, in the construction and operation of solar power plants, the connecting cables of solar power plants still use conventional cables. Because conventional cables do not consider the complex and changeable environment of photovoltaic power plant use and laying in the design and manufacturing process, they cannot meet the requirements of use, resulting in frequent quality problems of photovoltaic power plants. In particular, the quality problems caused by the performance of conventional cables themselves cannot meet the requirements of the power station environment. Photovoltaic cables are designed according to the complex and changeable operating environm
