price: contact company for price
The Manual Wire Bending Tester is designed to evaluate the mechanical durability of electrical wires according to the JIS-C3005 standard.
By bending wire samples repeatedly through preset holes, the tester assesses damage, cracking, surface cracks, and conductor strand breakage.
The instrument features simple operation, bidirectional rotation, and automatic stop after reaching the preset number of cycles.
Application
(1) Automotive wire harness testing – evaluate conductor integrity under repeated bending.
(2) Power cord quality control – ensure mechanical reliability of household and industrial cords.
(3) USB and data cable durability – simulate repetitive bending during normal use.
(4) Electrical appliance wiring – check wire insulation and conductor performance.
(5) Laboratory R&D – test new wire materials for bending fatigue resistance.
Standards
(1) JIS C 3005 – Testing method for flexible cords Parameters
