What is a wire and cable flexure testing machine?
In today's industrial production and quality inspection fields, the wire and cable flexural testing machine is an important testing equipment, mainly used to evaluate the durability and reliability of wires and cables under repeated bending conditions. With the rapid development of electric power, communications, transportation and other industries, the quality requirements for wires and cables are getting higher and higher, and the role of flexural testing machines has become increasingly prominent. This article will introduce in detail the definition, working principle, application fields and related technical parameters of the wire and cable flexural testing machine.
1. Definition of wire and cable flexural testing machine
The wire and cable flexural testing machine is a testing equipment that simulates the repeated bending of wires and cables during actual use. With this equipment, you can test whether wires and cables will break or have insulation damage after being bent multiple times to evaluate their service life and safety.
2. Working principle of wire and cable flexural testing machine
The flexure testing machine drives the fixture through a motor to repeatedly bend the wire and cable sample at a certain angle and frequency. During the test, the equipment records the number of bends and monitors changes in the electrical and mechanical properties of the wires and cables. Common testing standards include GB/T, IEC, UL and other international and industry standards.
| test items | Test standards | Test parameters |
|---|---|---|
| Number of bends | GB/T 5023.2 | More than 10,000 times |
| bending angle | IEC 60227 | 90° or 180° |
| Test frequency | UL 2556 | 30 times/minute |
3. Application areas of wire and cable flexural testing machines
Wire and cable flexural testing machines are widely used in the following fields:
| Application areas | Specific use |
|---|---|
| Electric power industry | Testing the durability of power cables |
| Communication industry | Evaluate the bending performance of communication cables |
| automobile manufacturing | Testing the reliability of automotive wiring harnesses |
