The same brand of two USB cable appearance looks the same, the price is different, a lot of people don't know why, actually connoisseur knows, in addition to the plug of the USB cable material differs character, a more important factor is it wire specifications different, lead to the function of the two USB cable is very different, take charge, two USB charging speed is not the same, a fast, a slow, fast charge, of course, the price must be a little more expensive.
< / p> < / p> USB cable can generally in appearance, such as AWM 2725, E159272 such words, this is the line body according to the design specification information.
UL and CSA standard focuses on wire can withstand temperature, voltage, and the wire type and appropriate USES, covers the area is quite broad.
Mobile equipment transmission power conditions, compared with residential, business environment, industrial purposes, low voltage and power flow is like a pediatrician.
In normal use situation, but don't too care about this difference, you just need to know its literal meaning.
< / p> if you want to charge of choose and buy USB cable, so you only need to focus on AWG specification, relevant evidence of wire rod structure, also can check it online body appearance, its print on common for 28 AWG 26 AWG / / 2 c + 2 c or 28 AWG / 1 p, 26 AWG / 2 c such patterns.
AWG is on behalf of the American Wire the Gauge American Wire Gauge, this is an internal component design specification of a Wire, also is the most widely used industrial standard.
The number for wire number, namely to the diameter of the wire (
< / p> AWG numerical is smaller on behalf of the wire diameter thicker, as to why the numerical small conductor wire diameter thicker instead?
Focus is the cross-sectional area differences.
USB wire line, interior is made up of many tiny soft soft copper wire, tin copper wire and other types of wire, such as 20 awg is into 26 * 0.
28 awg 16 wire, and only 7 * 0.
Relatively, 20 awg wire diameter are coarse, cross-sectional area greater than 28 awg nature.
And these tiny wire, the wire diameter and carry electricity flow is proportional to the, that is, the more coarse, the higher the tolerances.
< / p> for USB cable general application, AWG numerical outsiders can withstand through electromagnetic flow rate will be higher, the key lies in cross-sectional area.
Of course, AWG is industrial design specification, and on the premise of safety.
Due to the quality of wire rod production and using the environment temperature, will cause great influence to the conductivity, one of many variables is difficult to do, so can only design specification to find out the reference datum.
Key idea is to buy the zheng big eyes, as far as possible choose line body is relatively thick, appearance and AWG specification high wire.
< / p> suitable cinda, founded in 2004, has 13 years of production experience, is a professional development, design, manufacturing, selling all kinds of USB cable, the company has a complete and scientific quality management system, passed the ISO9001 international quality management system certification.
Has a perfect production line and sales channels, products are exported to Europe and the United States and other developed countries in the Middle East.
