Bow Type Laying Up Lines

The Bow Type Laying Up Line is a high-performance cabling solution engineered for the final assembly stage of multi-core power and control cables, where individually insulated cores are helically wound together to form a compact, round cable structure ready for sheathing. The bow-type design uses rotating bow frames mounted around the central cabling axis, allowing each core to be laid with consistent pitch and precise geometric alignment throughout the entire run. This machine is built to handle demanding cabling requirements, accommodating conductor cross-sections of up to 4×240mm² per core — a capacity that positions it squarely in medium to large power cable production. 
The rigid mechanical structure and precision-balanced rotating components enable stable high-speed operation without vibration-induced pitch variation, a common failure point in conventional laying up equipment operating at elevated line speeds. Tension on each individual core is independently controlled, preventing differential elongation between cores that would otherwise cause helical geometry inconsistencies or internal mechanical stress in the finished cable. The synchronized drive system ensures that lay direction and pitch remain uniform from the start of the reel to the end, a critical requirement for cables destined for armoring or outer sheath extrusion in subsequent production stages. The laying-up sequence and pitch are fully programmable, supporting both left-hand and right-hand lay configurations as required by different cable construction standards. 
The line is compatible with a range of filler and binder tape application systems that can be integrated inline, reducing the need for separate downstream processing steps. This bow-type laying up line is well suited for manufacturers producing multi-core power cables, flexible control cables, and instrumentation cables across energy, infrastructure, and industrial sectors. It is designed to comply with cable construction requirements under IEC 60228, IEC 60502, and related international standards.
