Driven by the global energy transition and "Net Zero" carbon goals, grid modernization demands higher transmission efficiency and lower construction costs. Leveraging deep expertise in bimetallic composite materials, FISSOT provides innovative conductor solutions for overhead power lines and global electrical transmission projects.
We are committed to breaking through material science boundaries to reduce transmission loss, extend infrastructure lifespan, and empower the "Power Highways" of the future. Our conductors overcome the limitations of traditional single-material solutions through advanced composite technology that optimizes electrical performance while ensuring mechanical reliability.
Recommended Products
Modernizing global power grids requires balancing electrical efficiency with infrastructure costs. For high-voltage overhead transmission lines, FISSOT recommends Copper Clad Aluminum (CCA) wire. By leveraging the Skin Effect, our CCA conductors deliver electrical performance equivalent to pure copper but are over 40% lighter, significantly reducing the mechanical load on transmission towers and cutting CAPEX by 30%+. For critical lightning protection and overhead ground wires, our Copper Clad Steel (CCS) stranded conductors provide the ultimate combination of high tensile strength, thermal stability, and long-term corrosion resistance.
Why Choose FISSOT?
CCA vs. Pure Copper: Which is better for overhead power lines?
For high-voltage AC overhead lines, Copper Clad Aluminum (CCA) is the superior choice. Thanks to the “Skin Effect”, high-frequency alternating current travels primarily along the outer surface of a conductor. CCA utilizes a highly conductive pure copper outer layer to transmit power efficiently, while its aluminum core significantly reduces both weight and material cost. It delivers electrical performance equivalent to pure copper but is specifically optimized for overhead transmission grids.
How to reduce power transmission line weight without losing conductivity?
The most effective engineering solution is replacing traditional solid copper with bimetallic conductors like CCA wire. FISSOT’s CCA conductors are approximately 40% lighter than pure copper of the exact same diameter. This dramatic reduction in weight exponentially decreases the mechanical tension on transmission towers, allowing for longer span lengths, reduced sag, and significantly lower civil engineering and infrastructure costs.
What are the most cost-effective power grid conductors?
Bimetallic wires, specifically CCA (Copper Clad Aluminum) and CCS (Copper Clad Steel), are widely recognized as the most cost-effective power grid conductors. They can reduce initial material expenditures (CAPEX) by over 30% compared to solid copper. Additionally, because bimetallic wires have a lower scrap value than pure copper, they effectively deter theft, drastically lowering long-term maintenance and replacement costs (OPEX) for utility companies.
