There are obvious differences between armored cables and unarmored cables in terms of structure, scope of application and use.
Construction: The main difference between the two is that armored cables add a layer of metal reinforcement to the outside of the metal casing made of insulating material, while unarmored cables do not have this layer of reinforcement.
Scope of application: Since the surface of the armored cable has a reinforcement layer, it is more suitable for use in environments buried underground or needing to withstand large external mechanical forces. There is no reinforcing layer on the surface of unarmored cables, so they generally cannot be buried. However, in other situations, such as simple indoor or overhead installation, unarmored cables can be used.
Use: Armored cables are mainly used for underground burialrain and are suitable for direct burial and laying in situations where significant external mechanical forces must be withstood. Unarmored cables cannot be used underground and are primarily used in other situations that do not need to withstand significant external mechanical forces.
In general, the choice of cable to use should be determined based on the scenario and the actual needs of the application.
