Armored Cables

Armored Cables

Armored cables are a type of cable that features an additional layer of metallic protection, usually in the form of mesh or foil, used to provide greater mechanical strength and protection against electromagnetic interference. These cables are widely used in applications where increased durability and shielding capability are required.

Structure:

They consist of several key components:

Conductor: It is the conducting core that carries electric current. It may be composed of copper, aluminum, or other conducting materials.

Insulation: Surrounds the conductor and electrically isolates it. A dielectric material, such as PVC (polyvinyl chloride) or XLPE (cross-linked polyethylene), is used to prevent short circuits and current losses.

Shielding: It is a metal layer surrounding the insulation and is used to protect against electromagnetic interference. It may consist of wire mesh or metal foil.

Filling: Used to fill the spaces between the shielding and insulation, providing an additional layer of mechanical protection and dimensional stability to the cable.

Outer Sheath: It is the outermost layer of the cable and provides protection against environmental factors such as moisture, heat, or abrasion. A resistant material, such as PVC or polyurethane, is used to protect the internal components of the cable.

Applications of Armored Cables:

They are used in a wide range of applications where increased strength and protection against electromagnetic interference are required. Some common examples include:

Industrial Applications: Armored cables are ideal for industrial environments where adverse conditions such as vibrations, impacts, moisture, or presence of chemicals exist.

Telecommunications: Armored cables are used in communication networks to avoid electromagnetic interference and ensure stable and reliable signal transmission.

Marine and Subsea Applications: Armored cables are used in marine and subsea installations, such as oil platforms, submarine communication systems, and ocean exploration equipment.

Security Systems: Armored cables are used in security systems, such as closed-circuit television (CCTV), alarms, and access control systems, to protect signals from external interference and ensure data transmission integrity.

Benefits of Armored Cables:

They offer a number of important benefits compared to conventional unshielded cables. Some of these benefits include:

Greater Mechanical Strength: The metallic protection layer provides greater resistance to traction, bending, and torsion, making the cables more durable and suitable for demanding environments.

Protection Against Electromagnetic Interference: The metallic shield protects against external electromagnetic interference, preventing it from affecting signal quality and ensuring more stable transmission.

Better Performance Over Long Distances: Due to their shielding capability.
