Before a cable assembly leaves our facility, it goes through destructive testing to confirm it meets both mechanical and electrical safety standards.

1. Pull-Force Test

We apply a pulling force higher than what the terminal manufacturer requires. This ensures that the crimp is mechanically strong and won’t fail under stress.

2. Cross-Section Analysis

We cut and polish the crimped terminal to examine the inside structure. This allows us to check that:

• All copper strands have been compressed correctly
  
  
• There are no voids or air pockets
  
  
• The compression is compact and uniform
  

Some real test samples from our lab:

These steps help us ensure that the cables can safely carry the required current and voltage, and resist the heat and vibration present in real-world applications.
