How to make or what sort of term or construction to look for in cable
specs?


The only wire that meets your requirement is intended for direct
burial, and is called 'Flooded cable' Nasty stuff to work with. It is
made for CATV, Networking and TELCO applications. Stock up on good
industrial hand cleaner and a bale of paper towels if you decide to use
it.

Sounds like fighting fire with fire. How to avoid liquid migrating along a
core - flood the interior with liguid.

Had a go chopping off a 2 inch length of hotmelt glue stick. Ground a crude
chisel on one end of a length of 1mm rod and drilled/melted through the
stick, pulled out while still warm. heated a copper wire cable core and
pushed through.
Covered with some heatshrink and a ceramic bead at the open end to keep
roughly centralised. Heating the copper and sleeving with hot air gun and
allowing the hotmelt to ooze out until contracted down, then cutting off
bead
section.

Cut it open to check and seemed a good bond but will repeat and stand in
some water with potassium permanganate on the upper end of the hotmelt
section and leave for a few days
