What acceptance testing voltage level is recommended for shielded cables according to ICEA and AEIC standards?

The recommended acceptance testing voltage level for shielded cables, according to ICEA and AEIC standards, is typically set at 80% of the final factory DC test voltage. This standard is established to ensure that while the cable can endure the stresses of higher voltages at the factory testing stage, the acceptance testing phase should not exceed certain thresholds to minimize the risk of damage or insulation failure during practical application.

Conducting acceptance tests at 80% strikes a balance between validating the integrity of the cable and ensuring its reliability under operational conditions. It allows for a thorough assessment while safeguarding the cable against potential over-voltage scenarios that could lead to insulation breakdown or other failures if higher levels were used.

This strategy is rooted in the need to comply with safety and performance criteria, ensuring that cables are capable of performing effectively without introducing unnecessary risk from excessive testing voltages.
