Have you ever faced such dilemmas?
On rainy days, traditional power transmission conductors shake violently in strong winds, risking breakage with even the slightest mishap;
When erecting lines in mountainous areas, dense towers have to be built to cross canyons and rivers—each additional tower adds a huge cost;
What’s more frustrating is that the conductors rust and corrode within just a few years. Workers have to climb towers for frequent maintenance, and electricity fees are wasted away due to transmission losses...
These long-standing headaches for power professionals have now been completely solved by a "power transmission black technology" — the Aluminum Conductor Multi-Strand Carbon Fiber Composite (ACMCC). With its three core advantages of "lightweight, cost-saving, and long-lasting", it has become the preferred solution for UHV power transmission and new energy grid connection!
I. Three "Awesome Advantages" — Explained in Plain Language
Compared with traditional steel-cored aluminum strands, the advantages of this Aluminum-Conductor Multi-Strand Carbon Fiber Composite (ACMCC) are not empty talk, but tangible "cost savings + peace of mind":
✅ Light Enough to Cross Rivers and Mountains — Saving Millions in Construction Costs
Its total weight is 30% lighter than traditional conductors, doubling the tower span directly! Previously, 10 towers were needed to erect lines in mountainous areas or across rivers — now only 6 suffice. It can even achieve cross-river spans of over 1,000 meters, significantly reducing investment in towers and foundation projects. Construction costs in complex terrain drop by as much as 50%.
✅ Power Loss Drops by 15%-20% — Earning Millions More Annually
Power loss during transmission is significantly reduced, equivalent to a county saving millions of yuan in electricity fees every year! For new energy power stations and cross-regional power transmission projects, the electricity fees saved over long-term operation are pure profits. It not only aligns with the "dual carbon" goals but also boosts project returns.
(In the figure below, a 100km, 500kV transmission line is constructed using stranded carbon fiber composite core conductors instead of steel-cored aluminum strands)
For the ACMCC, the annual line loss reduction amounts to 33.92 million yuan — the line loss saved in approximately 15 months can offset the additional one-time investment cost. Over its 30-year full life cycle, the total savings in electricity fees reach 1.017 billion yuan.
✅ Durable and Low-Maintenance: No Frequent Overhauls for 50 Years
It completely eliminates the electrochemical corrosion issue of steel cores, resisting rust and aging. Its outdoor service life reaches 40 - 50 years, more than twice that of traditional conductors. Workers no longer need to climb towers for frequent maintenance, slashing operation and maintenance costs by 80% directly. It enables the transmission line to achieve "one-time investment and long-term benefits".
II. Ideal for These Scenarios with Unmatched Cost-Effectiveness
Whether it is grid-connected power generation of new energy power stations (enhancing transmission efficiency and reducing power loss), ultra-high-voltage (UHV) cross-regional power transmission (meeting the demands for long-distance and large-capacity power delivery), or power line erection in complex terrains such as mountainous areas and river zones (cutting down the number of transmission towers), this overhead electrical stranded conductor with stranded carbon fiber composite core (ACMCC) is perfectly suitable. Currently, it has been widely applied in national UHV projects and has become a core driver in the upgrade of power infrastructure.
