Armored Cable
The armored cable is a type of cable that is reinforced by a metal structure integrated into its sheath. This metal structure can be made of steel, of aluminum or other metals and is generally used to increase the strength and resistance of the cable to tension and pressure.
Description of ZMS Armored Cable
ZMS armored power cable is made from high quality steel or aluminum, providing additional mechanical protection and higher tensile loads for applications where the cable is buried underground.
We can also manufacture armored cable to British standards, American, European and international.
Of course, we can also adapt them to your needs. You can send us a request by email.
Our sales team will design a program based on the specific project requirements.
Our technical team can solve complex structural problems.
SWA cable – Steel Wire Armored Cable
SWA cables are generally used for outdoor electrical power distribution applications, where they must withstand harsh conditions like rain, snow and mechanical shocks. The twisted steel frame gives them excellent resistance to traction and bending, which makes SWA armored cable particularly suitable for direct burial in the ground or for fixing to electrical poles.

STA cable – Steel Ribbon Armored Cable
The cable has a core composed of insulated conductors, surrounded by a layer of steel tape. The steel ribbon is wrapped around the core in a helical pattern, which ensures a high degree of mechanical protection. STA armored cable are commonly used in power transmission and distribution systems, as well as in telecommunications and other applications where mechanical protection is required.

AWA cable – Aluminum Wire Armored Cable
It is similar to an STA cable, but it uses aluminum wire to provide mechanical protection. The cable is made up of a core of insulated conductors, which are surrounded by a layer of aluminum wire. The wire is wrapped around the core in a helical pattern, which ensures a high degree of mechanical protection. AWA cables are commonly used in power transmission and distribution systems, as well as in telecommunications and other applications where mechanical protection is required.

ATA cable – Aluminum Tape Armored Cable
It is made up of several conductors which are wrapped in a layer of aluminum tape, which is then covered with a protective outer sheath. Aluminum tape provides a high degree of mechanical protection to conductors, which allows the armored ATA cable to be used in environments where the cable may be subject to physical damage. It is commonly used in underground applications, outdoor and industrial.

Types of Armored Cables and Their Applications
There exists several types of armored cables, each having its specific applications. Here are some common types of shielded cables :
Steel wire/ribbon armored cable (PRIVATE) : This type of cable is manufactured with a layer of galvanized steel wire or tape armor that serves as mechanical protection. It is often used in underground applications, like buried electrical cables, and exterior walls.
Aluminum wire/tape armored cable (AWA/ATA) : Similar to SWA/ATA cable, this type of cable is made with a layer of aluminum wire or tape armor. It is often used in power distribution and transmission applications, as well as in building construction.
Armored fiber optic cable (FOA) : This type of cable is used to transmit data over long distances using light signals. It has an armored protection layer, usually made of Kevlar or other very resistant materials, to protect the delicate fibers it contains.
Difference between STA and SWA
The metal protection layer of armored cable is generally divided into steel wire armored cable (STA), steel wire armored cable (SWA), aluminum wire armored cable (AWA) and aluminum ribbon cables (ATA). STA has advantages such as high strength and corrosion resistance, but it is heavier. And SWA, as for him, has advantages such as good flexibility and flexability, but its corrosion resistance is lower. The ATA is lightweight and corrosion resistant, but its resistance is lower.
Utilisation: STA armor can withstand transverse mechanical stresses, making it suitable for cables in direct burial installations or in conventional pipelines, in common ground, in the tunnels, among others. SWA cable can withstand general longitudinal stresses and is therefore suitable for short distance overhead installations or vertical and overhead installations.
Prix: SWA armored cable is more expensive than STA cable, because it is more difficult to produce and therefore costs more.
Magnetic shielding effect: STA steel armor has high permeability and good magnetic shielding effect and is suitable for resistance to low frequency interference, but it cannot completely replace the shielding layer of the cable.
