Specific analysis of specific issues:
1. Both braiding and armoring provide shielding, but armoring also provides moisture and pressure resistance.
2. Braiding is produced using weaving equipment and has a mesh-like appearance, while armoring (steel wire) is produced using cage-type stranding equipment and has a stranded appearance.
3. Because armoring is a structural form, while braiding is a manufacturing method, for example, braiding can be used for shielding or armoring. Armoring comes in various forms, including steel tape wrapping, steel wire armor, and braided armor.
4. In terms of function, braiding is more of an outer conductor, while armoring provides more protection.
5. In addition to providing shielding, braiding can also improve mechanical strength, such as providing a certain degree of tensile strength. Armoring (steel tape and wire) can provide both compressive and tensile strength, such as in submarine cables and mining cables.
6. That depends on the intended use. Braiding can also be used as a conductor, but it's mostly used for shielding and also provides some tensile strength. Armoring primarily provides protection and is generally used on Central Asian and high-voltage cables, while braiding is primarily used on cable.
7. Wires that move frequently are generally braided with copper wire, while those that don't move often are braided with armor or steel wire.
8. Braiding is produced using braiding equipment. Braiding steel wire is also a form of armor and is used in marine cables. It has a mesh-like appearance, and the armor (steel wire) is produced using cage stranding equipment.
9. Armoring primarily provides protection. It is braided between the inner and outer sheaths to provide shielding and is braided directly onto the core wire.
10. The primary purpose of armoring is to enhance the cable's tensile and compressive strength, as well as its water-blocking properties, providing protection. Braiding, on the other hand, primarily addresses electromagnetic interference in the cable's operating environment. The purpose of conventional tinned copper wire braiding is shielding, while armoring's shielding function is merely a secondary function. Similarly, braiding also provides stress-reducing benefits, but these two functions are distinct. The diameter of the steel wire can be determined by the braided outer diameter, while the braid density (P) is calculated as (2p-p²)*100%. P refers to the unidirectional coverage of each group of steel wires.
11. Braiding is a processing technique, and different braiding materials achieve different purposes, such as concentric conductors, shielding layers, and armor layers. Armoring is a structure, and different forms of armor are used to achieve different purposes, such as steel tape armor, wire-wound armor, and braided armor.
12. Armoring protects the sealing sheath from mechanical damage. Galvanized steel strips, steel wires, or copper strips or wires are typically wrapped around the outer sheath (called armored cable). The armor layer simultaneously shields the electric field and prevents external electromagnetic interference. To protect the steel strips and wires from corrosion by the surrounding medium, they are typically coated with asphalt or wrapped with impregnated jute or extruded polyethylene or polyvinyl chloride sheathing.
13. A shielding layer is formed by wrapping a layer of metal foil or braided metal wire around the insulation of an insulated wire or insulated cord. Connecting the shielding layer to a fixed potential reduces interference from external electromagnetic waves on the current within the wire and also reduces the impact of the electromagnetic field generated by the current within the wire on the outside world. It is primarily used in circuits where mutual interference prevention is required.
