In the interlocked type of armored data and power transmission cable, galvanized types of steel and aluminum are widely used, for increased durability, armored cable has a coating of wire or tape reinforced with galvanized steel or aluminum alloy.
Galvanized steel interlocked armored cable features
It is reasonable to anticipate dangers associated with armored cables, such as shock or pressure from outside sources, given the environment in which they are utilized.
Because of this, an uninterrupted layer of the alloys discussed before wraps around the inner wires of the armored cable to extend its useful life and boost its tensile strength.
In multi-stranded cables, the protective layer is typically composed of steel, but in single-stranded cables, the protective layer is typically made of aluminum.
Because steel and aluminum respond differently to the presence of a magnetic field, many alloys have been utilized in the construction of the protective layer.

It is important to remember that aluminum alloys are not magnetic and are unaffected by magnetic fields because of this property.
The use of armored cables in urban high-voltage distribution networks is the primary use for armored cables, and the presence of armored cables helps to prevent a variety of issues from arising.
Because of the way that these cables are constructed, the conductor, which is one of their primary components and is typically in the form of copper wire in these cables but aluminum in high voltage transmission cables, is one of the most important parts of these cables.
In the construction of armored cables, the insulation is often made of PVC, however, if waterproofing and electrical resistance are necessary, XLPE insulation is utilized instead.
The polyvinyl chloride that makes up its base layer serves as a barrier of protection between the insulating layer and the layer that is exposed to the environment.
The cable armor is an additional important structure of these wires.
The cable armor is the protective layer that shields the cable from high voltages.

In multi-stranded cables, the cable armor is typically made of steel, while the cable armor used in single-stranded cables is typically made of aluminum.
It is important to keep in mind that the type of layer that is placed on the primary insulation of the cable, which is also referred to as the lead sheath, always serves to separate the two components of these cables from one another.
Different varieties of armored cables
- NYRY and N2XRY are two types of low voltage cables that feature steel wire reinforcing.
- Low voltage armored wires, including NYBY and N2XBY.
- Cables of medium voltage that are reinforced with steel wire are denoted by the following part numbers: N2XSYRY, NA2XSYRY, N2XSEYRY, and NA2XSEYRY.
- Cables with Armor Protection for Medium Voltage: N2XSYBY, N2XSEYBY, NA2XSYBY, and NA2XSEYBY
- SWA and STA are both types of steel-armored multicore cables.
- AWA and ATA are both types of aluminum-armored single-core cables.
Applications involving armored cables or armored cables themselves
Due to the high electrical resistance of this type of cable, it is typically installed in a potentially dangerous location.
For instance, it might be used in places that are dirty, oily, moist, or even infested with rodents.
On the other hand, one may argue that the oil and gas as well as the petrochemical industries are the most typical users of these cables.
It should be noted that the armored cable is secure against voltage and shock, and it also protects mice from destroying the wire.
Special glands are used to make the connection between these kinds of cables and other pieces of apparatus.
It is also important to mention that this type of wire and cable is utilized for installations either inside or outside of buildings, as fixed installations in basements, in water, pipe, and cable supports, as well as in open places that require a significant amount of mechanical protection.
