Accessories
| Name | Description |
|---|---|
| Cable-specific fixtures | Secure cable ends |
| T-shaped guide plate | Cable installation and routing |
| Curve forming mechanism | S-shape or U-shape routing simulation |
| Force sensors | Measure tension and fixed end load |
| Displacement sensors | Measure stroke and displacement |
| Print paper | Output for test data and curves |
| Fasteners | For fixing specimens |
Test Procedures
(1) Install the cable specimen according to the selected layout (straight, S-shape, or U-shape) per the applicable standard.
(2) Securely clamp both ends using the appropriate fixtures to prevent slippage.
(3) Set push/pull speed according to the relevant standard or company specification.
(4) Start the test; the system applies controlled push-pull forces while measuring force and displacement at both ends.
(5) Monitor the test to ensure smooth loading and consistent data collection.
(6) Upon completion of the specified stroke or cycle, stop the test.
(7) Record data, generate force–force and displacement–time curves, and calculate load and displacement efficiency.
Maintenance Information
(1) Regularly check the clamping fixtures, T-guides, and curve forming mechanisms for wear or loosening.
(2) Keep moving parts clean and lubricated.
(3) Periodically verify the calibration and accuracy of force and displacement sensors.
(4) Replace consumables such as print paper as needed.
(5) Ensure the control system and power supply are functioning properly.
