That use of linseed oil may have been suggested by the practice of
protecting steel tubing used in aircraft with linseed oil. However,
that application involved welding shut the tube after placing a small
quantity of the linseed oil inside it. The linseed oil oxidized before
the steel, thus limiting oxidation of the steel. Sealing the tube, by
welding and not by any organic or other permeable material, prevented
(or slowed) any exchange that might introduce more oxygen.
This process obviously can't work on open cables.
Hermetic seal requires solid metal, glass, or certain ceramic material,
fused together. Water and other gases permeate through rubber, plastic
and such materials. Those materials slow but do not stop exchange of gases.
