I think "pile of strands" is misleading; are you doing it right?
It is more a neat ring of strands with interior support enabling equal pressure all round which must be equivalent to at least half of a complete tube.
As for protection - apart from that against rodents, what advantage does it give against impact from spades and similar, not to mention mechanical diggers?
The cable will still be virtually ruined.
