Test Procedures
Mount the wire sample securely in the clamps, ensuring proper alignment with the sand belt.
Select the appropriate sand belt grit and install it on the drive rollers.
Set the desired applied load and ensure the load holder is properly positioned.
Set sand belt travel distance, speed, and number of cycles on the control panel.
Start the test; the sand belt moves continuously, applying uniform abrasion to the wire.
Monitor the test progress; the machine stops automatically after reaching the preset distance.
Inspect the wire insulation for wear, cracks, or damage and record the results.
Maintenance Information
Inspect sand belts before each test and replace worn or damaged belts.
Keep support rollers, guides, and load holders clean to ensure uniform abrasion.
Periodically calibrate the travel counter and verify applied load weights.
Lubricate moving parts as recommended to maintain smooth operation.
Check electrical connections and conductive strips for integrity before testing.
