Test Procedures
Mount the wire sample securely in the clamps, ensuring alignment with the abrasion belt.
Install the desired sand belt and check tension.
Apply the standard load (54 g) to the sample using the load holder.
Set the abrasion travel distance, belt speed, and number of cycles on the control panel.
Start the test; the system moves the belt at the specified speed, applying uniform abrasion to the sample.
Monitor abrasion progress; the system stops automatically after reaching the preset distance.
Inspect the wire insulation for wear, cracking, or damage after testing.
Maintenance Information
Inspect sand belts before each test and replace if worn or damaged.
Clean abrasive support and guide surfaces to prevent uneven wear.
Check conductive strips for integrity and proper spacing.
Lubricate moving parts regularly to ensure smooth belt operation.
Verify applied load and belt speed calibration periodically.
