Cable Flexing Tester – Continuous flexing stress simulation according to IEC 60227-3, VDE 0281-3, BS EN 50525-2-31

ZONSKY's Cable Flexing Tester simulates severe, continuous bending stress to guarantee the mechanical lifespan of your wire products.

Product applications: Measures critical performance data including fatigue resistance, insulation breakdown, and conductor durability. Helps manufacturers ensure that flexible cables meet strict structural and mechanical safety standards.

Key features: Versatile multi-wheel design (customizable two- or three-wheel setup). Real-world fatigue simulation through continuous sample flexing. Single station, one sample per test cycle.

Complies with standards: IEC 60227-3, VDE 0281-3, BS EN 50525-2-31, NFC C 32-201, UL 62.

Main technical parameters:
