Flexural testing machine
Product introduction:
Wire bending test machine is suitable for testing the ability of optical cable (such as elevator optical cable) to withstand repeated bending in operation. By applying repeated bending force, it is required that the optical fiber is not broken for qualified optical cables, and the attenuation change of the optical fiber does not exceed the detailed specification of the optical cable product. The value specified in, the cable sheath is not cracked, and the cable core components are not damaged.
The features of the wire bending testing machine are man-machine interface and PLC control, TFT true color screen to display test parameters and test data, speed inorganic speed regulation, beautiful appearance, stable performance, simple operation and safe use.
Product introduction:
The wire bending test machine meets the standard: it is designed and manufactured according to the VDE0472 standard.
The wire bending test machine is used to detect the damage degree of the flexible cable of rubber insulation and sheath after a certain number of bending under the dynamic load.
