What does cable armor mean?

　　Cable armor refers to the addition of a protective layer of metal material to the cable, similar to a layer of "armor" to the cable to enhance its mechanical strength, compressive strength, tensile strength, etc., while improving the cable's anti-corrosion ability and anti-interference performance. This kind of cable is usually called armored cable.

　　Specifically, the protective layer of the armored cable can be made of metal materials such as steel strip, steel wire, aluminum strip, and aluminum tube, which have high strength and good magnetic conductivity. The armored layer not only protects the cable from external physical damage, such as wear, extrusion, and tearing, but also prevents SMall animals such as rats from biting the cable, ensuring stable transmission of power or signals.

　　In addition, the armored cable also has a certain anti-interference performance. The armored layer can shield the external electromagnetic interference, ensuring that the signal transmitted by the cable is not disturbed or weakened. This is especially important for occasions where high-quality signals need to be transmitted, such as communication, data transmission, audio and video transmission, etc.

　　Armored cables are usually used for fixed laying, that is, they do not move after being installed in one place. They are widely used in the fields of chemical industry, metallurgy, machinery manufacturing, power generation and scientific testing, for temperature measurement, signal transmission and special heating. In addition, armored optical cables are often used in military, national defense, underground facilities, industrial environments, marine environments and aerial devices to provide reliable communication and data transmission.

　　Overall, cable armor is an effective means to improve the mechanical strength, anti-corrosion ability and anti-interference performance of cables, and is widely used in various applications that require high reliability and stability.
