Wire Harness Inspection Methods

Wire Integrity Inspection: Inspect each wire individually to ensure its serial number, specifications, and quality meet requirements.

 

Wire Harness Assembly Inspection: Connect the wire harness to relevant equipment and check for proper operation.

 

Insulation Performance Test: Use an insulation tester to test the insulation performance of the wire harness to ensure no leakage.

 

Withstand Voltage Test: Perform a withstand voltage test on the wire harness to ensure it can withstand a certain voltage without damage.

 

Wire Harness Inspection Standards

Wire quality meets requirements, with no damage, breakage, or exposed wires.

 

Wire harness dimensions meet design requirements and are securely fixed.

 

The insulation performance of the wire harness should meet relevant standard requirements and there should be no leakage.

 

The withstand voltage performance of the wire harness should meet relevant standard requirements and be able to withstand voltage within the normal operating range.
