New equipment for solar cable packaging

lengths, markings and spool labels while the machine is running, optimising efficiency and minimising downtime. The “print reset to zero” capability ensures accurate printing of cable speci- fications, and the in-line operation op- tion eliminates the need for a separate rewind process, enhancing efficiency with speeds of up to 500m/min. Windak’s latest project for solar cable packaging was finalised in June and shipped to a customer in Korea. The AR24-D line included modern test equipment, automated PE film application unit (Wrap-App), a label applicator, and a two-axis spool palletiser equipped with an automatic pallet gripper and pallet dispenser.

In response to growing global demand for renewable energy sources, Windak has developed a new solution for solar cable packaging. The Windak AR series spoolers offer efficiency and innovative features, including precision winding and tension control; intelligent scrap handling (ISH) system; “no break” stretch wrap system; quick changeover between product sizes; optional labelling, boxing and palletising; and an operator-friendly design. The spoolers can handle a wide range of cable diameters from 3 to 20mm (0.12" to 0.8") and reel sizes between 216 and 800mm (8.5" to 32") in diameter. The “change on the fly” functionality allows real-time adjustments. Manu- facturers can seamlessly update cable

Mastering busbar insulation Modern electric vehicles (EVs) are equipped with high-voltage com- ponents that require a stable and efficient power supply.

Even minor deviations can noticeably impact wall thickness distribution, so precise control from payoff to take-up is required for maintaining quality. Every line component must be precisely calibrated to achieve seamless production. Rosendahl’s busbar insulation solution pays special attention to the conductor cleaning process before extrusion, and proper cooling afterwards. These measures ensure a high level of adhesion between the aluminium or copper conductor and the insulation layer – a primary quality factor for the final product.

than traditional cables, resulting in a reduction of power loss. Their distinctive flat shape is optimised for efficient use of the space available within a vehicle’s electrical construction. Busbars are more challenging to process than traditional cables with round cross sections.

For busbars to perform their function safely over the entire service life, high quality insulation is necessary. In July 2011, Rosendahl commissioned the first busbar insulation line. Since then, with the rise of e-mobility, these high-performance “flat cables” have gained significant importance. They have become an integral part of EVs, facilitating the conduction and distribution of power within electrical systems. The main advantage of busbars is their ability to handle higher currents
