RE: cable armor
From Pirelli:
"Available armour types:
1. Interlocking armour of aluminum or galvanized steel.
2. Galvanized steel wire armour. On single conductor cable, this type of armour is available per ICEA S-66-524 Section 4.
3. Double steel tape armour (DSTA). This armour consists of two layers of gapped galvanized steel tape applied over the inner jacket followed by an outer jacket.
Note: Steel interlocking and steel tape armours are not recommended for single conductor cables due to the excessive magnetic losses."
I would stick with the interlocking aluminum armour unless these cables are to be vertically suspended for some distance, in which case the steel wire armour would be preferred for supporting the cable.
