AWG means American Wire Gauge, a standardised system of measuring the cross-sectional area of Shuguang Tubes. 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 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 had been a solid circular wire, then AWG is rather straightforward to calculate. Go ahead and take area (pi x radius squared) to have the cross-sectional area, and appear up the AWG chart (example below) to determine AWG. If a cable has multiple strands, an identical operation is performed to work through the cross-sectional section of each strand, which can be then simply just multiplied by the number of strands to have the total AWG. However be cautious when you compare this figure as AWG is not really linear. For each and every extra 3 AWG, it is half the cross-sectional area. So 9 AWG is about one half 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 the smaller the AWG, the bigger the cable. Larger cables could have less DC resistance, which results in less power loss. For applications to home theatre, this is certainly true as much as a level. A principle is the fact for smaller speakers, a cable of about 17 AWG is plenty, whereas for larger speakers anything up to 12 AWG or more will provide you with great results.
The reason some cables of the same 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 of the plastic jacket to help make the cable appear thicker. This isn’t necessarily bad, as up to and including point increased jacket thickness reduces other unwanted properties. Just make sure that you don’t do a comparison by sight.
Another factor why Copper Colour Cable may look different in thickness is just how the internal strands are made. Some cables have thinner strands, while others have thicker strands. Depending on the size and placement of these strands, cables can be created to appear thinner or thicker compared to they are.
Is AWG a great indicator of quality? In a nutshell, no. A big AWG (small cable) may certainly be too small for a particular application (for example, you shouldn’t be employing a 24 AWG cable to run your front speakers). However, AWG is a way of measuring quantity, not quality. You need to make certain that all your speaker cables are of at the very least OFC purity.
Does AWG matter? How so? AWG certainly matters. You have to be sure that the cable you happen to be using is enough to handle the power you’re likely to put through them. Additionally, in case you are carrying out a longer run, then fxxwky more thickness will be required. However, some people get trapped a lot of in AWG and forget the truth that when a sufficient thickness is reached, additional factors come into play. This then becomes more a matter for “audiophile” features to solve, like using higher quality materials including silver conductors or improved design.
Wire gauge is unquestionably an excellent fundamental indicator of how sufficient MUZISHARE is made for the application. However, it is actually 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 a smaller factor, whereas for most hi-fi applications 18-19 AWG is the minimum cables to make use of.
