The choice between overhead power lines and underground cables depends on a variety of factors, and neither is universally "better."

• Overhead Power Lines: These are the most common and cost-effective solution for long-distance transmission. They are easier to install, maintain, and repair, as faults are visible and accessible. However, they are more susceptible to weather-related damage from wind, ice, and storms.

• underground Cables: These are often preferred in densely populated urban areas, where aesthetics and space are a concern. They are more reliable in severe weather and have a lower visual impact. However, they are significantly more expensive to install and repairs can be complex and time-consuming, as locating a fault requires specialized equipment and digging.

Our company, Ningbo Changshi, specializes in a full range of equipment for both overhead and underground power line projects, enabling our clients to choose the best solution for their specific geographical and logistical needs.
