Product No: WDT-B42
The WDT-B42 Flexing Test Apparatus for Flexible Cables is used to test the damage of rubber-insulated and sheathed flexible cables after repeated bending under dynamic load conditions. The equipment uses a specific structure to make the sample reciprocate within a set stroke, simulating the bending state of the cable in actual use. Simultaneously, it can accurately monitor abnormal conditions such as wire breakage and short circuits during the test, ensuring the reliability of the test data. It is easy to operate and can reliably meet relevant testing requirements.
Test principle: A 5m long specimen is reciprocated within a 1m stroke through a pair of pulleys to achieve bending test of wires and cables.
