Cold impact testing assesses whether a cable can withstand impact forces after being subjected to low temperatures without cracking and continue to maintain insulation properties. After exposure to a specified freezing temperature, a controlled mechanical impact is applied to the cable, simulating real-world scenarios such as accidental drops, crushing, or bending. The cable’s performance is then assessed by a voltage withstand test.
Parameters that may be adjusted include:
- Mass of impact force
- Conditioning temperature
- Duration of conditioning
