Answer: underground cables offer several advantages, including improved environmental aesthetics, lower maintenance due to protection from weather and vandalism, and enhanced safety. They are the preferred choice in densely populated urban areas and environmentally sensitive regions. However, they present challenges such as higher initial installation costs, more difficult and time-consuming fault tracing, and thermal management issues due to poor heat dissipation. We provide specialized underground cable laying equipment and tools designed to address these challenges, ensuring efficient installation and long-term reliability.
