Flexible cables testing equipment can meet the different requirements of dynamic bending and bending test for flexible wires and cables made by wire and cable manufacturers and inspection departments. Flexible cables testing equipment from Wewon Environmental Chambers Co., Ltd. can choose a variety of test loads and comply with test standard such as IEC 227-2 IEC 245-2 UL1581 VDE0472 IEC 60227-2(ed2)1997 IEC60245-2(ed2)1994 HD22.1 188.8.131.52 184.108.40.206 GB5023.2 GB5013.2
In addition to the electrical performance and other basic requirements of flexible wire and cables that can match the equipment, the most important basic feature is that wire & cable bending test apparatus can withstand regular bending, torsion, extension, shearing and other mechanical stresses to ensure normal operation. The flexible cable flexure test is a test item that is used to simulate the actual working environment of the flexible cable through multiple bends and stretches to assess whether the flexibility and structural stability of the flexible cable meet the long-term use requirements of the product.

The flexible cable bending test is suitable for multi-core PVC insulated and sheathed flexible cables and flexible cables with a core cross-sectional area not exceeding 2.5mm2. The bending test device is shown in the figure below, including a trolley equipped with a driving device and a flexible cable. The four pulleys for testing the cable sample and the weights at both ends. The installation of the four pulleys should make the sample horizontal.
According to the test model, number of cores, and cross-sectional area of cores, determine the diameter and load mass of pulleys A and B, sample test current and test voltage according to standard requirements.
Flexural Test Process
Take the sample about 5 meters long and install the sample according to the requirements of the standard. Note that the angle between the axis of the pulleys A and B is 45° with the track, and the three sections of cables installed between the pulleys are in a horizontal state.
Adjust the limit clamps (D) at both ends to make the cable sag naturally, and add weights of suitable quality to both ends and apply the load current and voltage specified by the standard.
Set the reciprocating times of the counter to 1 million reciprocating movements, start the flexure test device, and the trolley will move back and forth between a distance of 1 meter at a constant speed of about 0.33m/s to make the specimen bend back and forth. stretch.
After the flexural test, all samples on the wire & cable bending test apparatus are tested for the voltage of the finished cable.
Wewon’s polyvinyl chloride insulated cable testing equipment manufactured according to IEC 60227-2 test standard’s requirements. It is suitable for the bending (bending) test of cables by related manufacturers and quality inspection departments. The specific test method is to fix the cable on the fixture and swing the fixture to the left and right during the test. After a certain number of times, the testing machine will automatically stop operating and then check the total number of swings.
