Underground Armored Cable — SWA/AWA

Armoured cable

ZMS manufactures armored cables that are made of high-quality steel or aluminum. We supply high-quality armored cables to the world. We can manufacture a variety of rugged low voltage armored cables or medium voltage armored cables according to British, American, European, and international standards, etc. Armor cables are suitable for applications that are buried directly underground and require additional mechanical protection and superior tensile loading. We are well-known cable manufacturers in the world.

Description of ZMS Cable

Types of underground armored cable are :
SWA (steel wire armored) cable, STA (steel tape armored) cable, AWA (aluminum wire armored), and ATA (aluminum tape armored). It is suitable for underground or outdoor cables with single or multiple core conductors. Like Copper single/multicore armored cable or Aluminum single/multicore armored cable.
The Underground Armored Cable mechanical protection layer can be added to any structure of the cable. To increase the mechanical strength of the cable and improve the ability to prevent corrosion. It is a cable designed for areas subject to mechanical damage and erosion. Can be laid in any way, more suitable for direct buried laying in rocky areas.

Steel Wire Armored Cable — SWA

SWA(Steel Wire Armored) cable is a high-strength, abrasion-resistant cable whose structure provides additional mechanical protection for itself. Armoring reduces the risk of the cable being torn or crushed. Generally, SWA cables exist in underground systems, power networks, cable ducts, outdoor installations, power control systems, etc.

Aluminum Wire Armored Cable — AWA

AWA(Aluminum Wire Armored) cable is used for single-core cables because it is non-magnetic. So when a current passes through the cable, a magnetic field is generated (the higher the voltage, the larger the magnetic field). The magnetic field will induce a current (eddy current) in the steel armor, which may cause the AC system to overheat. Non-magnetic aluminum armored cables prevent this from happening.

Characteristics of Armored Cables

An armored cable mechanical protection layer can be added to any structure of the cable to increase the mechanical strength of the cable and enhance the erosion resistance. It is a special cable designed to avoid mechanical damage and erosion-prone areas. It can be laid in any way and is suitable for direct burial in rocky areas. Simply put, the armored cable is also known as an underground power cable. The purpose of power line transmission cable with armor layer is not only to enhance the tensile strength, compressive strength, and other mechanical protection to extend the service life. The armor has the necessary resistance to external forces and can also put some rats to tear. To ensure that the power transmission problem is caused through the armor, the bending radius of the armor should be larger, and the armor layer can be grounded to protect the cable.
