What are SWA cables?
SWA cables have a strong mechanical protection. This means that they are durable and extremely reliable even under the most extreme conditions. Understandably, they are somewhat more expensive than conventional cables. For price reasons, most people often avoid most types of armoured cables, even if they perfectly suit their wiring needs. Choosing ordinary cables can lead to expensive replacements and repairs. In the long run, it is cheaper to use SWA cables. To get a better price, it is advisable to ask for prices from several SWA cable suppliers. Considering that there are many of them, you are likely to find a cheap SWA cable.
When do I need to use SWA cables?
The main characteristic of SWA cables is their ability to withstand harsh conditions. It is therefore preferable to use SWA cables when dealing with any electrical application that is susceptible to physical damage. Such applications include industrial fixed power installations, residential underground power systems and power networks
What is the difference between AWA cables and SWA cables?
Essentially, AWA stands for aluminium wire armouring and due to its non-magnetic properties, AWA wire is mainly used for single core cables. As the current passes through the cable, it generates a magnetic field.
The magnetic field becomes stronger with each increase in voltage. This magnetic field induces eddy currents in any SWA conductor, which usually leads to overheating of the AC system. Therefore, the non-magnetic nature of the AWA is essential as it prevents the AC system from overheating. Given that SWAs can cause significant damage to AC systems, it is best to use them in outdoor or underground applications. In addition to providing mechanical shielding capabilities, the armouring of SWA cables can also withstand high tensile loads. SWA cables are currently used in several industries, including construction and transport.
What is the best way to lay armoured cables underground?
If you are considering laying SWA cables underground, you must ensure that you use the right cable. XLPE SWA cables are a good example of cables that can be used for underground installations. Nevertheless, regardless of the type of cable you use, there are certain rules that need to be followed when carrying out an underground installation. For example, you must discuss the regulations governing underground installations with your local inspector and obtain permission. How do I bury an armoured cable? The following are some expert tips that you need to follow.
Firstly, you must decide how much you are willing to dig, as it determines the type of cable you need to use.
Assuming you are using direct buried armoured cable without conduit, you must dig 12 inches deep. You must also ensure that the SWA cable has GFCI protection before it is buried.
