Withstand testing can be performed on either new or aged cables. The test should only be done if there is concern that cable damage has occurred possibly during installation or the insulation has been compromised due to heat, water or chemicals.

General Testing Information

  • The test can be conducted with AC or DC voltages.

  • AC Withstand Test for field acceptance is 80% of factory test voltage. See table below.

  • DC Withstand Test for field acceptance is three times greater than the AC Withstand Test. See table below.
