Description

The hard casing bending test machine, designed for non-metallic and composite conduits, assesses the bending performance of insulating electrical conduits. A specific bending aid is inserted into the sample prior to testing. The sample is secured using a forming mold and clamps. The equipment’s bending mechanism induces bending at a predetermined angle. Post-test, the sample is inspected for visible cracks, and the smooth passage of a corresponding gauge through the conduit is verified to ensure structural integrity and bending resistance. The apparatus adheres to regulations, ensuring a stable and controllable bending process, providing objective evidence for quality inspection of conduit products. Standards include IEC 61386-1:2017, GB/T 20041.1-2015, GB/T 14823.2-2017, JG 3050-1998, and ZBG 33008-1990.
