AI Technical Summary
Existing membrane-wrapped stranded wires are prone to stress concentration in the overlap area, wear or displacement at the overlap in high-dynamic application scenarios, which leads to a decrease in the stability of the stranded structure and the reliability of insulation.
The double-layer film overlap area is circumferentially staggered, and the combination structure of inner and outer stranded layers and overall winding layer is combined. The stranding forming process, which limits the wire feeding sequence through guide holes, adjusts tension, rotates and presses, and controls adjustable damping torque, ensures that the film overlap area is distributed in the cross section and that the outer layer is stably bound.
It improves the geometric stability and insulation reliability of stranded wires under repeated bending and torsion conditions, reduces the risk of wear and displacement of the cladding, and enhances the long service life and outer diameter consistency of the cable.
