In the
Wire And Cable manufacturing industry, raw material costs account for over 80% of total production expenses. Key materials such as copper, aluminum, steel cores, rubber, plastic, and protective sheaths form the backbone of these costs. As a result, wire and cable companies must focus on designing unique products, optimizing material usage, and developing eco-friendly alternatives. To build a sustainable circular economy in this sector, the following strategies should be prioritized:
First, it is essential to phase out outdated technologies like cold-rolled black copper rods. The process of producing 8mm black copper rods using cold rolling mills is considered inefficient and environmentally harmful. These rods have high oxide content, poor electrical conductivity, low tensile strength, and lead to excessive energy consumption and pollution. Eliminating this method is crucial for improving product quality and reducing environmental impact.
Second, the adoption of advanced aluminum rare earth optimization technology should be accelerated. Although continuous casting and rolling processes for electrical aluminum rods are widely used in China, the equipment remains largely based on 1970s technology with limited innovation. Introducing unique Chinese aluminum rare earth treatment methods, along with upgrading coal-fired melting furnaces to fuel or natural gas alternatives, can significantly reduce emissions and improve efficiency. This also increases the operating temperature of cables from 70°C to 150°C, boosting current-carrying capacity by 1.6 times.
Third, there is a need to actively introduce advanced foreign technologies while independently developing high-performance specialized equipment for wire and cable production. Currently, key production machinery lags behind international standards, with issues such as low productivity, poor automation, high energy use, and unreliable performance. By investing in research and development, companies can enhance product quality, production efficiency, and material utilization, supporting the transition toward a circular economy.
Finally, the development of environmentally friendly wire and cable products must be prioritized, alongside strengthening waste recycling systems. Many polymer materials like rubber, PVC, and polyethylene are commonly used, but their production releases toxic gases. Companies should shift toward eco-friendly materials and follow global standards, as seen in Japan’s Fujikura, which has successfully promoted green cable products. With growing market demand, traditional and flame-retardant cables struggle to compete. Additionally, residual materials from production can be recycled and repurposed. Establishing dedicated PVC recycling facilities would help manage waste effectively, prevent secondary pollution, and support sustainable practices in the industry.
