Answer: The choice between 22kV overhead lines and underground cables depends on factors like cost, safety, and environmental impact. overhead lines, using bare or Aerial Bundled Cable (ABC), are generally more cost-effective and easier to repair, but can be susceptible to damage from weather, animals, and vegetation. underground cables offer greater reliability and are often preferred in urban areas or locations with high bushfire risk, as they are protected from external elements.

Ningbo Changshi provides a comprehensive range of equipment for both applications. For overhead lines, we supply all the necessary transmission line tools, accessories, and stringing equipment. For underground projects, our cable laying equipment and tools, such as cable pullers and rollers, are designed for efficient and safe installation. We help our clients choose the right equipment for their specific project needs.
