Armor is a protective layer, typically made of metal, that is used to protect cables from damage. It is generally used in areas where the cable may be exposed to the environment, such as outdoors or in industrial settings.

Armor is designed to protect the cable from physical damage, such as cuts or abrasions, as well as from other environmental hazards, such as water, excessive heat, and ultraviolet radiation. Armor is usually made of a metal material, such as aluminum or steel, which is strong enough to resist any physical damage. It is usually wrapped around the cable in a spiral pattern, which helps to disperse any force that is applied to the cable.

The amount of armor that is used depends on the application. For instance, in an industrial setting, where the cable may be exposed to higher levels of wear and tear, thicker armor is typically used. On the other hand, in a residential setting, a thinner armor may be sufficient to protect the cable.

Armor also helps to prevent the cable from becoming tangled or snagged and can help to reduce the amount of noise that is generated by the cable. Additionally, armor can provide electrical shielding, which helps to protect the cable from interference from other electrical signals. This is especially important for cables that are used for data transmission.

Overall, armor is an important component of any cable system, as it helps to protect the cable from physical damage and environmental hazards, as well as providing additional protection from electrical interference. By using armor, you can ensure that your cables are able to provide reliable performance for a long period of time.
