Typically, the armour is made of one or two layers of wires, round or flat in shape, made of steel with low to medium carbon content (for example ranging from less than 0.015% to up to 2%). Steel is generally used due to its low cost, availability of supply and good mechanical properties. Other materials used for the cable armour can be galvanized (e.g. zinc-coated) steel, copper, brass, bronze. Galvanized steel is preferably used when the armour wires are exposed to the environment without any polymeric sheath or yarn layer, to ensure better resistance to corrosion.

Answer:
In high voltage cables, the armor is an essential component that provides mechanical protection and shielding. The material used for the armor should possess specific properties to ensure the safe and efficient operation of the cable. Among the options provided, steel is the most suitable material for the armor of high voltage cables.
- Strength: Steel is known for its high strength and durability, making it an ideal choice for armor. It can withstand high mechanical stress and protect the cable from external forces.
- Conductivity: Steel has good electrical conductivity, which helps in maintaining the grounding of the cable and prevents the build-up of static charges.
- Corrosion Resistance: Steel can be galvanized or coated to enhance its resistance to corrosion and environmental conditions, ensuring the longevity of the cable.
- Flexibility: Steel armor can be manufactured in various forms, such as wires or tapes, allowing flexibility in the cable design and installation process.
- Cost-effectiveness: Compared to other materials, steel is relatively inexpensive and readily available, making it a cost-effective choice for cable armor.
- Mechanical Protection: Steel armor provides excellent protection against physical damage, such as impact, compression, and abrasion, which may occur during cable installation or operation.
- Electromagnetic Shielding: Steel armor acts as a shield, preventing the interference of external electromagnetic fields and minimizing signal distortion or loss.
- Fire Resistance: Steel is a non-combustible material, making it highly resistant to fire hazards. In case of a fire, the steel armor can help contain the flames and prevent them from spreading.
- Longevity: The durability and corrosion resistance of steel ensure the longevity of the cable, reducing maintenance and replacement costs.
Steel is the most suitable material for the armor of high voltage cables due to its strength, conductivity, corrosion resistance, flexibility, and cost-effectiveness. It provides essential mechanical protection, electromagnetic shielding, and fire resistance, ensuring the safe and efficient operation of the cables.
