Traction chain cable, also known as flexible cable for traction chains, soft cable for traction chains, or special cable for traction chains, is a type of cable specifically designed for use in dynamic environments. The following is a detailed introduction:
Structural Features
Tensile Center In the center of the cable, within the space of the cross-section area of each core wire, a real centerline filler is set up to protect the stranded wire structure.
Conductor Structure Optimized diameter and length of single wires are selected to achieve the best tensile capacity and flexibility.
Core Insulation High-pressure-formed PVC or TPE materials that do not stick to each other, ensuring long-term reliability.
Stranding Wound around a stable tensile center with optimal lay length. Bunch-stranding method adopted for 12+ cores.
Inner Sheath Extruded in an armored-style manner to ensure the stranded wire structure remains intact.
Shielding Tightly braided layer with optimized angles to resist torsion and maintain EMC protection.
Outer Sheath Improved materials with UV, low-temperature, and oil resistance, featuring high wear resistance.

Differences from Ordinary Cables
Ordinary flexible cables are used for power transmission or signal transmission in fixed positions, while traction chain cables are specifically designed for movement in traction chains. They have high flexibility and wear resistance and can prevent cable entanglement, wear, pulling off, hanging, and scattering.
