The Automotive Wire Repeated Bending Tester is designed to evaluate the durability of automotive wires under repeated bending conditions. It can be combined with a low-temperature chamber to perform bending tests under various environmental conditions, simulating real-world automotive wiring stress.
Application
(1) Automotive wiring harnesses – assess flexibility and resistance to repeated bending.
(2) Low-voltage cables – verify insulation and conductor integrity under cyclic mechanical stress.
(3) R&D laboratories – test new wire formulations for mechanical reliability.
(4) Production quality control – ensure wires meet bending durability standards.
(5) Environmental testing – evaluate performance under low-temperature conditions using an optional temperature chamber.
Standards
ISO 14572:2011 – Test method for the bending performance of electrical wires
