Steel-armoured cable protects power lines from cuts, crushing, and damage.
Steel wire armour shields conductors and provides a safe earth path.
Armoured cable suits outdoor and underground runs; unarmoured fits indoors.
2-core suits single phase; 4-core supports three-phase distribution.
Copper offers higher conductivity; aluminium is cost-effective for long runs.
Armoured cables fall under HSN 8544; pricing varies by size and metal.
