Transient fire environment cable damageability test results: Phase 1
The results of a series of 13 cable tests using IEEE-383 qualified and unqualified cable are discussed in this report. The purpose of these tests was to determine cable damage response (as indicated by electrical failure) to transient fire environments (temperature vs time only). The major insights gained from these tests were that (1) cables terminated in a fire environment are more likely to fail; (2) cable geometry plays a significant role in determining if a cable will fail; (3) convective heat transfer, i.e., high air flow regions, leads to severe cable damage; and (4) based on simulated, air cooled down suppression, neither qualified nor unqualified cables would fail given the suppression actuation times and test profiles used in these tests. This assumes that suppression agents (e.g., water) do not cause damage.
