But, how do these advanced cabling requirements affect machine manufacturers and technology integrators?
Machinery for Advanced Cabling: A Technological Synthesis
As previously mentioned, cutting-edge wire and cable production requires extensive technological advancements. Machinery experts combine separate technologies to build machines that efficiently produce high-quality wires and cables. With rising demand for specialized cables across power transmission, data connectivity, e-mobility, and automation, the manufacturing technologies are facing constant pressure to become cutting-edge.
Consequently, manufacturers are transforming production by combining advancements in extrusion, stranding, insulation, sheathing, and quality control. Not to say, these new machines are enhancing efficiency and product reliability while aligning with sustainability goals. Let’s quickly look at innovative developments in crucial cable manufacturing fields.
Advanced extrusion technologies play a key role in high-voltage power cables, fiber optics, and automotive wiring. Wire and cable manufacturing fundamentally relies on extrusion for the precise application of insulation and sheathing materials to conductors. Maintaining material integrity and performance requires strictly controlling temperature, pressure, and cooling rates during the process. Advanced extrusion lines incorporate multilayer co-extrusion, cross-linking techniques, and real-time monitoring systems to enhance efficiency and quality.
AI-powered automation within the extrusion process guarantees consistent insulation thickness and excellent electrical performance. In EVs, specialized PEEK extrusion is widely used for hairpin winding, reducing energy loss and improving system efficiency. Aman Arora of Rosendahl Nextrom explains, “Hairpins in electric vehicle stators allow for higher voltages, thus decreasing energy loss and improving motor efficiency and reliability. Mikko Lahti, Maillefer’s R&D Director, highlights key developments such as energy-efficient extrusion and cutting-edge insulation/sheathing technologies for minimizing excess material.
High-precision measuring and quality control systems are critical for maintaining strict performance standards. Advanced tools, including X-ray scanners, ultrasonic gauges, and optical diameter measurement systems, are essential for real-time monitoring of insulation thickness and detection of inconsistencies. Non-destructive testing of cable cores is achieved through X-ray solutions, whereas ultrasonic testing guarantees proper adhesion between insulation layers. Additionally, high-speed laser micrometers deliver precise outer diameter measurements, helping manufacturers maintain tight tolerances.
Moreover, laser-based monitoring, capacitance testing, and AI-driven defect detection improve consistency and reduce waste. Real-time monitoring identifies deviations early, ensuring that high-performance cables for power distribution and data transmission meet stringent specifications. SIKORA, a producer of high-tech measuring tools, emphasizes, “It’s the single value accuracy that matters, not an average of multiple measurements.”
Stranding, bunching, and coiling innovations have optimized power transmission cables and industrial wiring. Flexibility, conductivity, and mechanical strength are improved by twisting multiple wire strands together in these processes. Stranding can be done in concentric, compacted, or sectoral formations, each suited to specific applications. Bunching, mainly used with flexible cables, creates even strand distribution; coiling precisely winds cables to avoid tangles and damage.
Real-time tension control and automated splicing in modern coiling and rewinding machines lead to more consistent production. The adoption of no-twist coiling technology minimizes handling damage and enhances storage efficiency. According to Jonas Hagsted, President, Lämneå Bruk, “Our flagship innovation, the No Twist Coiler (NTC) portfolio, has been in development since 1992 and has transformed wire manufacturing worldwide. It significantly boosts productivity without requiring changes to existing setups.”
Continuous casting and rolling (CCR) innovations have modernized wire rod production through the integration of energy-efficient melting and refining, resulting in decreased power usage. The process begins with liquid metal being continuously cast into a strand, which is then hot-rolled through successive stands to achieve the desired diameter and mechanical properties. In advanced CCR systems, electromagnetic stirring improves metal purity and uniformity, and inline surface treatment minimizes defects and oxidation. In addition, maintaining exact temperatures during rolling creates the best grain structure, which improves the final product’s conductivity and its durability.
Advanced rolling mills boost conductivity, curb oxidation, and self-annealing technologies slash energy use by as much as 50%. Continuus-Properzi, a major machine maker in this segment, highlights, “We have dedicated particular attention to the reduction of electrical consumption during the casting, rolling, and coiling. Our SAM system enables up to 50% energy savings with no copper dust creation.”
Smart manufacturing, AI, and automation (Industry 4.0) are transforming production. Digital twin technology produces virtual copies of extrusion lines, allowing for real-time simulation and troubleshooting. IoT sensors track key factors like temperature, tension, insulation thickness to maintain consistent product quality. Predictive maintenance algorithms assess machine performance, thus minimizing downtime and averting defects proactively. Automated material handling systems boost production efficiency by reducing waste and improving resource allocation. Production is faster, more efficient, and less wasteful thanks to these advancements. Maillefer emphasizes this transition, stating, “Our new data storage solution will change how manufacturers collect and analyze production data.”
Sustainability and environmentally responsible manufacturing are gaining traction. There’s a growing trend toward using biodegradable insulation, halogen-free flame retardants, and energy-efficient materials. Cable manufacturers are now embracing circular economy principles and reducing plastic waste through recycling. “Sustainability is a top priority for manufacturers,” says Nicola Corti, Sales Director at MFL Group, “with a focus on reducing waste, energy, and materials to minimize environmental impact.” “We have engineered our machines to support biodegradable packaging materials, allowing cables to be securely packaged while reducing environmental impact,” says Dieter Gerger, Sales Manager at Windak, expanding on the subject. “In fact, our latest developments enable cable packaging without any plastic at all—a major step toward a greener future.”
Continued industry progress hinges on precision, automation, and sustainability. Companies specializing in extrusion, measuring systems, coiling automation, continuous casting, and smart manufacturing, such as Maillefer, Rosendahl Nextrom, FUHR, MFL Group, Lämneå Bruk, Windak, SIKORA, Continuus-Properzi, and many others continue to shape the next generation of wire and cable technologies.
