At Top Cable we have a wide range of armoured cables for optimum mechanical protection designed and produced by our team of experts. Armoured cables are hard-wearing power cables designed for the supply of mains electricity. Armoured cable usually means steel wire armoured cable (SWA cables).
What are SWA -steel wire armoured- cables?
Commonly known as SWA cable, the steel wire armoured cable is one that has a protective layer of metal around it. The purpose of this cable together with the shielding layer is to improve performance against interference by providing shielding protection, as well as to increase the durability of the mechanical protection, including tensile strength and compressive strength.
Where are SWA armoured cables typically used?
SWA (steel wire armoured cables) are commonly used in underground systems, power grids and outdoor lighting installations. The steel wire armour makes it suitable for direct burial and for locations where high durability is required.
What are the benefits of using armoured cables?
Armoured SWA cable offers several unique advantages. First, SWA cables are very resistant to wear and tear, as the shielding material is hard enough to protect the inner cable from damage. Second, these cables ensure good stability in power transmission. Third, SWA power cables have advanced mechanical properties. Therefore, they are ideal for environments with extreme weather conditions, where cables can be easily damaged by machinery, and in areas with a high presence of radio frequencies.
How are SWA armoured cables installed?
First, prepare the junction box where the cable will be installed. Secondly, determine the exact length of shielded electrical cable you will need to successfully complete the installation. Once you have established the appropriate length, cut the cable to the required length. Next, install the cylindrical anti-short-circuit sheathing at the junction between the shielded cable and the cable inside the junction box. Next, connect the connector to the cable and finally attach it to the junction box to complete the wiring process.
What are the mechanical protection properties of SWA cables?
Armoured cables are designed with several mechanical protection properties that make them suitable for challenging environments. These cables are impact and abrasion resistant, resistant to rodents, water and high temperature. These properties make armoured cables a reliable choice for various applications, including industrial, commercial, and outdoor installations.
How does the armour affect the flexibility of the cable?
The armouring of a cable usually influences its flexibility. Even so, Top Cable’s range of armoured cables have a flexible class 5 conductor, ensuring ease of installation in more complex layouts.
Are there different types of armoured cables for different applications?
Yes, there are different types of armoured cables designed for various applications. The main types include:
Each type of armoured cable is tailored to meet specific environmental conditions, mechanical stresses, and safety requirements, ensuring optimal performance for its intended use.
