Overhead power transmission lines are generally a more cost-effective and practical solution for transmitting electricity over long distances. Their main advantages include:

• Lower Cost: Both initial construction and long-term maintenance costs are significantly lower than for underground cables.

• Easier Maintenance: Faults are more easily located and repaired, leading to quicker restoration of power.

• Flexibility: They are easier to modify, re-route, or upgrade, making them adaptable to changing needs.

The main disadvantage is their susceptibility to damage from severe weather, wildlife, and vehicle collisions. Our company, Ningbo Changshi, provides a full suite of OHTL tools and equipment that are engineered to enhance the safety and efficiency of construction and maintenance, helping to mitigate these risks.
