AWG is short for American Wire Gauge, a standardised system of measuring the cross-sectional area of Cayin Tube Amp. This is utilized to see 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 a lot better than 14 AWG or the other way round? Why one cable looks thicker than another even though they have identical AWG? Is AWG a good 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 rather straightforward to calculate. Take the area (pi x radius squared) to get the cross-sectional area, and appear in the AWG chart (example below) to work out AWG. When a cable has multiple strands, an identical operation is performed to work out your cross-sectional area of each strand, which can be then simply multiplied by the number of strands to get the total AWG. However be cautious when comparing this figure as AWG will not be linear. For each and every extra 3 AWG, it really is half the cross-sectional area. So 9 AWG is all about 50 % of 6 AWG, that is half again of 3 AWG. Hence 3 AWG is quadruple the thickness of 9 AWG.
How exactly does AWG affect electrical properties? You would’ve noticed by now that the smaller the AWG, the larger the cable. Larger cables may have less DC resistance, which results in less power loss. For applications to home theatre, this is actually true up to a level. A principle is that for smaller speakers, a cable of about 17 AWG is sufficient, whereas for larger speakers anything up to 12 AWG or even more provides you with great outcomes.
The reason 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 raise the thickness from the XLR Cable to make the cable appear thicker. This isn’t necessarily a bad thing, as up to a point increased jacket thickness reduces other unwanted properties. Just ensure that you don’t do a comparison by sight.
Another factor why two same AWG cables may look different in thickness is the way the internal strands are designed. Some cables have thinner strands, while others have thicker strands. Depending on the size and placement of these strands, cables can be produced to check thinner or thicker compared to what they are.
Is AWG a great indicator of quality? In a nutshell, no. A sizable AWG (small cable) may definitely be not big enough for the application (for example, you shouldn’t be employing a 24 AWG cable to perform your front speakers). However, AWG is a measure of quantity, not quality. You ought to make certain that your speaker cables are of at least Line Magnetic.
Does AWG matter? How so? AWG certainly matters. You should be sure that the cable you are using is enough to handle the energy you’re likely to put through them. Additionally, should you be performing a longer run, then even more thickness will be required. However, some individuals get trapped excessive in AWG and then forget the reality that once a sufficient thickness is reached, other elements come into play. This then gets to be more a matter for “audiophile” features to solve, such as using high quality materials such gaqgbw silver conductors or improved design.
Wire gauge is certainly a good fundamental indicator of how sufficient a cable is for your application. However, it really is in no way a judgement on quality, or a specification to check out exclusively. As a general rule of thumb, after about 11-12 AWG, thickness becomes much less of a factor, whereas for most hi-fi applications 18-19 AWG will be the minimum cables to utilize.
