What is AWG?

The two USB data cord of the same brand look the same, but the price is different. Many people don’t know why, except for the connector material of the USB data cable, the more important factor is that the wire specifications are different.  The functions of the two USB charging and data sync cable are completely different. In terms of charging, the charging speed of the two USB data lines is different. One is fast and the other is slow, of course, the price of charging faster is definitely more expensive.


USB data lines are generally able to find such words as AWM 2725, E159272 in appearance, which is the design specification information that the line body follows.  The UL and CSA specifications focus on the temperature and voltage values that wire can withstand, as well as the type of wire and suitable use, covering a wide range of fields.  Mobile devices transmit power conditions, compared to home, business environment, industrial use, the voltage and current levels are low, just like a piece of cake.


If you want to buy a USB cable for charging, then you only need to pay attention to the AWG specification. The information on the wire structure can also be found on the online body. For example, the printed type is generally 28AWG/2C+26AWG/2C or 28AWG.  /1P, 26AWG/2C and other such modes.  The AWG represents the American Wire Gauge American Wire Gauge, which is one of the design specifications for the internal components of wire and is the most commonly adopted industry standard.  The number is the wire number used to indicate the diameter of the wire in inches.


The smaller the AWG value, the thicker the wire diameter. Why is the wire with a smaller value instead thicker?  The focus is on the difference in cross-sectional area.  Each of the USB cable signal lines is made up of many small soft copper wires, tinned soft copper wires, etc. For example, 20AWG is inserted into 26*0.16 wires, while 28AWG is only 7*0.12.  Relatively speaking, each of the 20AWG wires has a relatively large diameter and a cross-sectional area naturally larger than 28 AWG.  The wire diameter of these small wires is proportional to the amount of current that can be carried, that is, the thicker the higher the bearing capacity.


For the general application of USB data lines, the AWG value can withstand the amount of passing current is necessarily higher, the key is the cross-sectional area.  Of course, the AWG is only an industrial design specification and is based on security.  Due to the quality of the wire production and the temperature of the environment, it has a great influence on the conduction characteristics. Many of the variables are difficult to complete, so the reference point can only be found by the design specifications.  Whenever possible, select a wire with a thicker appearance and a higher AWG size.
