For power line construction and maintenance, the primary conductor materials are copper and aluminum. At Ningbo Changshi, our equipment is designed to handle both of these materials, each with unique properties that make them suitable for different applications.

• Copper: Known for its high conductivity, durability, and a smaller size for a given current capacity. Copper is a preferred choice for many applications where space is limited or high performance is critical, such as grounding systems and certain underground cables.

• Aluminum: A lightweight and cost-effective alternative to copper. Although it has lower conductivity than copper, its low density makes it highly efficient for long-distance overhead transmission lines. We provide specialized tension stringing equipment for aluminum conductors, including ACSR (Aluminum Conductor Steel Reinforced) cables, which combine aluminum's conductivity with the mechanical strength of steel.
