7-core cables are problematic, above all over long distances and in small bend radii. The problem is the large stranding circumference that mainly occurs in the case of 7-core cables with cross sections of more than 1.0 mm. Due to the push/pull forces that act on the cores when the cable is bent, the cores […]
Cables with layered strands, 7 or more cores and a cross section of >1.0 mm² are especially at risk on long travels: The so-called corkscrew effect. This has an adverse effect on the cable’s overall structure and core breakages can occur. Cores wound in bundles counter this effect. Cable bundles with previously layered strands and […]
