AI Technical Summary
When spring cables are subjected to radial pressure or impact, the spiral of the cable is prone to flattening, resulting in excessive bending angle, deformation and breakage of the internal material, which affects the normal use of the equipment.
Spring cables are equipped with wound metal wires, an inner buffer layer, an outer buffer layer, a filler layer, and a protective layer. The elasticity and rigidity of the wound metal wires are used to withstand impacts, while the inner buffer layer and the filler layer provide deformation buffering to prevent the core from breaking.
It effectively prevents spring cables from deforming excessively under radial pressure or impact, avoids core breakage, and improves the durability and reliability of the cable.
