Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a novel flexible cable for a multi-environment energy storage system. Background Art

[0002] In recent years, with the rapid development of the new energy industry, the energy storage market, as a subsidiary sector, has also experienced explosive growth. Whether it's photovoltaic, wind power, hydropower, or other renewable energy sources, or traditional grids or internal combustion engine distributed energy sources, they all rely on the support of energy storage technology. The cable industry for energy storage systems has become a strategic hub in the energy transition. However, among renewable energy sources, wind and solar power generation is intermittent and unstable. Energy storage systems can work with wind, solar, and other energy sources to address grid issues: they can store excess electricity during off-peak periods and use it during peak periods, reducing energy waste. Furthermore, energy storage stations can reduce line losses, extend the life of lines and equipment, optimize system power layout, and improve power quality. Therefore, energy storage systems can promote the development of new energy, especially distributed photovoltaic and wind farms, which require energy storage systems to stabilize power generation.

[0003] During the installation process, cables are generally laid on the ground first. However, the existing cable protection performance is poor. Workers will step on the cables when walking. If there are stones on the ground, the cable core will break, which will cause certain hidden dangers during use. Utility Model Content
