Armored cables are electrical cables fortified with an additional layer of protection, typically a steel wire or tape armor. This "armor" provides exceptional resistance to mechanical stress, physical damage, and environmental factors like moisture and rodents. They are essential for power line projects because they ensure the longevity, reliability, and safety of electrical systems in harsh environments, such as direct burial underground, industrial facilities, and outdoor installations. For a high-quality installation, it is crucial to use specialized cable laying equipment to handle these robust cables without causing damage.
