Flex Tester Machine For Wires Two-Wheel/Three-Wheel

What is the Flex Tester Machine For Wires Two-Wheel/Three-Wheel？

ZONSKY Flex Tester Machine for Wires (Two-Wheel/Three-Wheel) is designed to evaluate the flexural endurance and mechanical resilience of wires under repeated bending cycles. Using a two- or three-wheel setup, this apparatus continuously flexes wire samples to simulate repetitive bending stress, measuring parameters such as fatigue resistance, insulation integrity, and conductor durability. 

Two-wheel flexure test: After 15,000 reciprocating movements of the flexible cable used to detect rubber insulation and sheath, that is, 30,000 single-way movements, neither current interruption nor short circuit between conductors should occur. Three-wheel flexure test: During 1000 times of reciprocating movement, that is, 2000 times of one-way movement, there should be no open circuit of the conductor, no short circuit between the conductors, and no short circuit between the cable and the pulley (test equipment).

Compliance：IEC 60227-3；VDE 0281-3；BS EN 50525-2-31；NF C 32-201；UL 62
