1. Applicable scope
This Drag Chain Bending Tester is suitable for repeated U-shaped bending fatigue testing of high flexible cables such as TUV, VDE, UL, etc., in applications that require continuous bending and high-speed movement, such as internal wiring of machines, high-speed drag chain system cables, connecting cables of machine moving parts, internal wiring of machines, as well as repeated bending fatigue testing of industrial drag chain cables and industrial robot cables.
The Drag Chain Bending Tester is mainly used to detect whether flexible cables are short circuited, and whether the insulation sheath is cracked, damaged, or other abnormal phenomena after repeated high-speed U-bend tests driven by drag chains. To detect the performance of metal conductors in withstanding plastic deformation and highlighting defects during repeated high-speed U-bend tests.
This Drag Chain Bending Tester meets the requirements of TUV 2PFG2577-08.16 and CRIA 0003.2-2016 "Industrial Robot Special Cables - Part 2: Test Methods" standards such as the China Robotics Industry Alliance.
