Damage control technology idea from real world railway news.
From recent news in the realm of the fireproofing of railway electronics, dig the transforming cable insulation;
CABLES: Nexans has launched its Flamex Ethernet FR range of fire-resistant communication cables, which are designed to maintain their integrity during a fire so that train crew can continue using key communication and control systems.
When exposed to fire, the cable insulation, transforms from a flexible plastic covering to a tough insulating ceramic layer.

I can see so many ways this can go bad...

Does it rigidize? if so, then falling debris can crack it...
Does it expand? if so, it means the fireblocks have to be flexible materials.
how high does it go? If it's higher than melt-point, then a crack might have the wire leak right on out.

Are you an engineer, that sounds just like the outlook of my several friends who are. :D But, seriously, failure modes and unforeseen interactions, especially unforeseen interactions, are something which really need to be thoroughly examined with spacecraft systems.

Nope, not an Engineer. But was raised by one. And trained in basics of Theology by Dominican friars, and have been an RPG GM for 37 years or so.

And, just for reference, Murphy was an optimist.
