The structure of this testing machine is of a horizontal type. The equipment's test chamber is equipped with a temperature control box, which can adapt to different testing environment requirements. This machine is mainly used to test whether cables will short circuit after undergoing repeated high-speed U-shaped bending tests, and whether the insulation sheath has cracks, damages or other abnormal phenomena. It is used to detect the plastic deformation performance and defects of the cables during repeated high-speed U-shaped bending tests. This testing machine is suitable for the high-flexibility cable inspection requirements set by TUV, VDE, UL, etc. It is mainly used in the quality supervision industry, cable and wire manufacturing, mechanical industry, as well as manufacturers of metals, steel wires, and ropes, etc.
