AWG means American Wire Gauge, a standardised system of measuring the cross-sectional area of Vacuum Valve. This is used to figure out 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 better than 14 AWG or the other way around? How come 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? When a cable had been a solid circular wire, then AWG is fairly straightforward to calculate. Go ahead and take area (pi x radius squared) to get the cross-sectional area, and look in the AWG chart (example below) to work through AWG. When a cable has multiple strands, a similar operation is carried out to determine the cross-sectional section of each strand, which is then simply multiplied by the number of strands to get the total AWG. However be cautious when you compare this figure as AWG is not really linear. For every extra 3 AWG, it really is half the cross-sectional area. So 9 AWG is about 50 % of 6 AWG, that is 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 at this point that the smaller the AWG, the larger the cable. Larger cables will have less DC resistance, which results in less power loss. For applications to home theatre, this is really true as much as a degree. A guideline is the fact that for smaller speakers, a cable of around 17 AWG is sufficient, whereas for larger speakers anything up to 12 AWG or more provides you with good results.
Why some cables of the same AWG look different in thickness? Two factors dominate here. Firstly, the AWG only takes into consideration the inner conductors. Therefore, a cable manufacturer could easily increase the thickness of the plastic jacket to create the cable appear thicker. This isn’t necessarily a bad thing, as up to a point increased jacket thickness reduces other unwanted properties. Just make certain you don’t compare them by sight.
One other factor why Copper Colour Cable may look different in thickness is 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 produced to check thinner or thicker than they are.
Is AWG a great indicator of quality? In a nutshell, no. A large AWG (small cable) may easily be too small for the application (as an example, you shouldn’t be utilizing a 24 AWG cable to perform your front speakers). However, AWG is a way of measuring quantity, not quality. You ought to ensure that all of your speaker cables are of at the very least 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 the power you’re going to put through them. Additionally, if you are performing a longer run, then fxxwky more thickness would be required. However, many people get swept up a lot of in AWG and forget the fact that when a sufficient thickness is reached, additional factors come into play. This then grows more a matter for “audiophile” features to settle, including using higher quality materials like silver conductors or improved design.
Wire gauge is undoubtedly an excellent fundamental indicator of how sufficient MUZISHARE is made for your application. However, it is by no means a judgement on quality, or perhaps a specification to consider exclusively. For the most part of thumb, after about 11-12 AWG, thickness becomes much a lesser factor, whereas for many hi-fi applications 18-19 AWG will be the minimum cables to utilize.
