AWG means American Wire Gauge, a standardised system of measuring the cross-sectional area of Cayin Tube Amp. This is used to see how much current a wire can handle. AWG causes much confusion for consumers, as the standard can be a little challenging to understand. Is 12 AWG much better than 14 AWG or the other way round? The reason 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 on how AWG is actually calculated.
How is AWG calculated? In case a cable was a solid circular wire, then AWG is fairly straightforward to calculate. Consider the area (pi x radius squared) to get the cross-sectional area, and appear up the AWG chart (example below) to work out AWG. When a cable has multiple strands, a similar operation is performed to work out the cross-sectional area of each strand, which is then simply just multiplied by the amount of strands to obtain the total AWG. However be mindful when comparing this figure as AWG will not be linear. For each and every extra 3 AWG, it is half the cross-sectional area. So 9 AWG is about half of 6 AWG, which is half again of three AWG. Hence 3 AWG is quadruple the thickness of 9 AWG.
How does AWG affect electrical properties? You would’ve noticed at this point that this smaller the AWG, the larger the cable. Larger cables could have less DC resistance, which results in less power loss. For applications to home theatre, this is really true approximately an extent. A principle is that for smaller speakers, a cable of approximately 17 AWG is plenty, whereas for larger speakers anything approximately 12 AWG or even more will provide you with good results.
The reason some cables of the identical AWG look different in thickness? Two factors dominate here. Firstly, the AWG only takes into consideration the internal conductors. Therefore, a cable manufacturer could easily increase the thickness from the CopperColour 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 how the internal strands are designed. Some cables have thinner strands, while some have thicker strands. Depending on the size and placement of these strands, cables can be produced to appear thinner or thicker than they are.
Is AWG an excellent indicator of quality? In a nutshell, no. A sizable AWG (small cable) may definitely be not big enough for the application (as an example, you shouldn’t be using a 24 AWG cable to operate your front speakers). However, AWG is actually a way of measuring quantity, not quality. You ought to make certain that all your speaker cables are of a minimum of Line Magnetic 518ia.
Does AWG matter? How so? AWG certainly matters. You have to be sure that the cable you happen to be using is sufficient to handle the power you’re going to put through them. Additionally, in case you are performing a longer run, then even more thickness could be required. However, many people get caught up a lot of in AWG and then forget the truth that after a sufficient thickness is reached, other factors enter into play. This then grows more a matter for “audiophile” features to settle, like using better quality materials such gaqgbw silver conductors or improved design.
Wire gauge is unquestionably a great fundamental indicator of methods sufficient a cable is for your application. However, it is actually by no means a judgement on quality, or perhaps a specification to check out exclusively. As being a general rule of thumb, after about 11-12 AWG, thickness becomes much less of a factor, whereas for the majority of hi-fi applications 18-19 AWG would be the minimum cables to make use of.
