AWG means American Wire Gauge, a standardised system of measuring the cross-sectional area of Vacuum Valve. This is used to determine how much current a wire can handle. AWG causes much confusion for consumers, as the standard can be a little difficult to understand. Is 12 AWG much better than 14 AWG or the other way around? Why one cable looks thicker than another even though they have identical AWG? Is AWG an excellent indicator of quality? Does AWG matter, and if so, how? These are all good questions, and we’ll get to them shortly. Firstly, let’s briefly touch about how AWG is actually calculated.
How is AWG calculated? If a cable was actually a solid circular wire, then AWG is pretty straightforward to calculate. Go ahead and take area (pi x radius squared) to obtain the cross-sectional area, and search the AWG chart (example below) to work out AWG. In case a cable has multiple strands, a similar operation is carried out to work out the cross-sectional section of each strand, which can be then simply multiplied by the quantity of strands to have the total AWG. However be mindful when comparing this figure as AWG will not be linear. For each extra 3 AWG, it really is half the cross-sectional area. So 9 AWG is approximately one half of 6 AWG, which can be half again of 3 AWG. Hence 3 AWG is quadruple the thickness of 9 AWG.
How does AWG affect electrical properties? You would’ve noticed right now the smaller the AWG, the larger the cable. Larger cables may have less DC resistance, which means less power loss. For applications to home theatre, this is actually true up to a level. A guideline is that for smaller speakers, a cable of approximately 17 AWG is enough, whereas for larger speakers anything approximately 12 AWG or even more will provide you with good results.
How come some cables of the identical AWG look different in thickness? Two factors dominate here. Firstly, the AWG only takes into account the interior conductors. Therefore, a cable manufacturer could easily increase the thickness in the plastic jacket to help make the cable appear thicker. This isn’t necessarily bad, as as much as a point increased jacket thickness reduces other unwanted properties. Just ensure that you don’t do a comparison by sight.
The other factor why Copper Colour Cable may look different in thickness is the way the internal strands are created. Some cables have thinner strands, while some have thicker strands. Depending on the size and placement of these strands, cables can be made to appear thinner or thicker compared to what they are.
Is AWG an excellent indicator of quality? In a nutshell, no. A large AWG (small cable) may definitely be too small for the application (as an example, you shouldn’t be utilizing a 24 AWG cable to operate your front speakers). However, AWG is really a measure of quantity, not quality. You should make sure that all of your speaker cables are of a minimum of OFC purity.
Does AWG matter? How so? AWG certainly matters. You should be sure that the cable you happen to be using is plenty to handle power you’re likely to put through them. Additionally, if you are doing a longer run, then fxxwky more thickness would be required. However, some individuals get trapped a lot of in AWG and end up forgetting the truth that once a sufficient thickness is reached, other factors come into play. This then becomes more a matter for “audiophile” features to solve, such as using higher quality materials such as silver conductors or improved design.
Wire gauge is undoubtedly an excellent fundamental indicator of methods sufficient MUZISHARE Audio is perfect for your application. However, it is actually by no means a judgement on quality, or a specification to look at exclusively. For the most part of thumb, after about 11-12 AWG, thickness becomes much less of a factor, whereas for most hi-fi applications 18-19 AWG is the minimum cables to utilize.
