What is a cable bending testing machine?
In today's industrial production and quality inspection fields, the cable bending testing machine is an important testing equipment used to evaluate the durability and performance of cables under repeated bending conditions. With the rapid development of electric power, communications, rail transit and other industries, the quality and reliability of cables have become key factors. This article will introduce in detail the definition, working principle, application scenarios and comparison of popular models in the market of cable bending testing machines.
1. Definition of cable bending testing machine
Cable bending testing machine is a testing equipment that simulates the repeated bending state of cables in actual use. By setting the number of bends, angles and speeds, it detects the insulation performance, conductor breakage, sheath wear and other indicators of the cable to ensure that it meets industry standards.
2. Working principle
Cable bending testing machines usually consist of drive systems, fixtures, counters and control systems. When working, the clamp fixes both ends of the cable, the drive system drives the cable to bend according to preset parameters, and the counter records the number of bends until the cable fails or reaches the set number.
| components | Function |
|---|---|
| Drive system | Provides power to control bending motion |
| fixture | Secure cables to ensure test stability |
| counter | Record the number of bends |
| control system | Set parameters and monitor the test process |
3. Application scenarios
Cable bending testing machines are widely used in the following fields:
| Industry | Application Notes |
|---|---|
| Electric power industry | Testing the bending durability of high-voltage cables |
| Communication industry | Evaluating the Repeated Bending Performance of Fiber Optic Cables |
| rail transit | Testing the reliability of train cables in vibration environments |
| Home appliance manufacturing | Verify the life of household appliance cables |
4. Comparison of popular models in the market
The following is a comparison of the popular cable bending testing machine models on the market recently and their main parameters:
| Model | Maximum bending angle | bending speed | Applicable cable diameter | Price range (yuan) |
|---|---|---|---|---|
| DL-1000 | ±180° | 10-60 times/minute | 5-50mm | 20,000-30,000 |
| HT-2000 | ±90° | 5-30 times/minute | 2-20mm | 15,000-25,000 |
| QC-3000 | ±360° | 20-100 times/minute | 10-60mm | 30,000-50,000 |
5. Purchase suggestions
When selecting a cable bend testing machine, consider the following factors:
1.Testing requirements: Determine parameters such as bending angle, speed, etc. based on cable type and testing standards.
2.Equipment accuracy: High-precision sensors and control systems can improve the reliability of test results.
3.After-sales service: Give priority to brands that provide technical support and warranty services.
6. Conclusion
Cable bending testing machine is an important tool to ensure the quality of cables and is widely used in many industries. Through the introduction of this article, I believe you will have a clearer understanding of the functions, applications and purchase of cable bending testing machines. If you need to know more about specific models or test plans, you can consult professional equipment suppliers.
