How does “Armoring” (SWA/AWA/STA) impact MV cable installation?

Armoring provides mechanical protection against impact and rodents:

SWA (Steel Wire Armor): Used for multi-core cables.

AWA (Aluminium Wire Armor): Mandatory for single-core cables to prevent electromagnetic heating (eddy currents) that would occur with magnetic steel armor.

STA (Steel Tape Armor): Offers excellent crush resistance and rodent protection for underground distribution.
