SFL geek and Amicus are correct about cold flow issues, I am just wondering how/why we think we know Honeywell used "thin teflon insulated wire" in the location where the issue occurred?
There was a list of approved wire for the 787, I very much doubt that was on it at all, and if it was it would have been for very specific applications, given it is known to have very poor cut-thru resistance, suffers from cold-flow and is heavy! The only real thing going for it is it's high temperature performance.
Assuming we are talking battery leads, I would expect it more likely that a single or double insulated wire with a polymer such as crosslinked ETFE or PDVF/PVF2 outer sheath would be called out?
Amicus, I too was wondering who actually fitted the batteries, given the production delays it is not beyond the bounds of possibility that the early deliveries of ELT were either without batteries or had them removed to be fitted later and given the focus on only units in 787...makes you wonder?
