What are the main types of armor the components of cable?

          1. Single or Double Steel Wire Armor (SWA, DSWA)

Construction: Made from galvanized steel wires wound around the cable.
Uses: SWA is commonly used in underground cables, and it provides excellent mechanical protection.
Benefits: High tensile strength and resistance to impact.



          2. Single or Double Steel Tape Armor (STA, DSTA )

Construction: Consists of two layers of steel tape helically wound around the cable.
Uses: Ideal for cables that need flexibility and medium mechanical protection.
Benefits: Good balance between protection and flexibility.



          3. Aluminum Wire Armor (AWA)

Construction: Made from aluminum wires wound around the cable.
Uses: Suitable for single-core cables in high voltage applications because aluminum is non-magnetic.
Benefits: Lightweight and provides corrosion resistance.

          4. Copper Tape Armor, Single Copper Tape Armour SCTA, Double Copper Tape Armour DCTA

Construction: Copper tapes are wound helically around the cable.
Uses: Provides protection and also acts as a conductor for electrical grounding.
Benefits: High electrical conductivity and corrosion resistance.



          5. Corrugated Steel Tape (CST)

Construction: Corrugated steel tape wrapped around the cable.
Uses: Used in cables that require high mechanical protection, such as direct burial installations.
Benefits: Enhanced protection against crushing and physical damage.



          6. Aluminum Interlock Armor (AIA)

Construction: Features interlocking aluminum tapes around the cable.
Uses: Used in various industrial and commercial applications where lightweight armor is preferred.
Benefits: Lightweight, flexible, and provides good protection against physical damage.



          7. Braided Armor ( Copper CBA, Aluminium ABA, Steal SBA, Bronze BBA )

Construction: Composed of interwoven metal wires, typically copper, aluminum, steel, bronze, etc.
Uses: Used in applications where flexibility and shielding against electromagnetic interference are necessary.
Benefits: It provides both mechanical protection, EMI/RFI shielding, and flexibility.



          8. Fiberglass Armor (Fiberglass braid FGB, Fiberglass tape FGT )

Construction: Consists of fiberglass yarns or tapes wound around the cable.
Uses: Often used in environments where non-metallic armor is required, such as explosive atmospheres.
Benefits: Non-conductive, lightweight, and provides thermal insulation.



          9. Lead Sheath Armor (LSA)

Construction: Composed of a lead alloy sheath.
Uses: Commonly used in environments where chemical resistance is required, such as in oil and gas industries.
Benefits: Excellent protection against moisture, chemicals, and gases.
