This ultra high flexible ultra high speed drag chain cable is particularly suitable for continuous high-load, ultra-high flexibility, and high-speed bending applications in mechanical equipment and machine tools. The ultra-high flexible cable uses specially modified insulation and sheath materials, as well as a special structure, which provides high wear resistance and resistance to media. It can withstand long-term acceleration, deceleration, stretching, compression stress, and over 20 million times reliability tests for drag chain
