The Wire And Cable Repeated Bending Tester is a professional testing instrument designed to evaluate the bending fatigue performance and durability of wires, cables, cords and flexible conductors. It complies with international standards such as UL817, VDE, GB/T238 and ISO 7801, widely used in wire manufacturing, quality inspection, laboratories and certification bodies.
The machine fixes the sample with adjustable fixtures and applies standard weights to simulate real‑use tension. It conducts left‑right repeated bending tests at a controllable speed of 10–60 times per minute, with bending angle and radius customizable for different cable sizes. It supports preset test counts up to 999,999 times and automatically stops when the conductor breaks or the circuit is interrupted, with real‑time data display and power‑off memory.
With stable structure, precise control and easy operation, it effectively detects material defects, conductor breakage, insulation cracking and aging risks, providing reliable data for product quality control and R&D optimization.

Wire and Cable Repeated Bending Tester principle
One end of the wire or cable is clamped, and a standard weight is applied to the other end to maintain constant tension. The testing mechanism drives the sample to repeatedly bend left and right at a set angle, radius, and speed. During continuous cycles, the machine simulates the bending stress encountered in real-world applications. It automatically counts the number of bends and stops the test if the conductor breaks or the circuit fails. By recording fatigue life data, this testing machine can evaluate the bending strength, durability, and structural stability of wires, cables, and their insulation materials.
Accuracy of repeated bending test machine for wires and cables
This Wire and Cable Repeated Bending Tester features high accuracy in bending angle, test speed, and cycle counting. It adopts a precise driving structure to ensure stable and consistent bending actions, with minimal deviation in angle and radius. The digital counter provides accurate test cycles with high repeatability and reliable data output. Constant tension control ensures uniform stress on samples during testing. Its high accuracy guarantees stable, repeatable test results, making it ideal for quality control, material evaluation, and laboratory reliability testing of wires and cables.
