In our daily life,   the USB cable will widely used on mobile phone charging, power bank charging and toy charging, etc., USB data cable is more common in people's lives. The market price gap is very big. Customers are also comparing the price of data lines.  Considering the quality of the product,  Sinodec Industrial Co., ltd.  will  interprets the price difference of the USB cable, mainly from the material cost of the data line.

USB cable

The USB cables frequently used in daily life are divided into two cores and four cores. The two core charging lead  are mainly used for charing, The four core data lines mainly add the green and white signal wires. If you want to analyze the material cost of the data lines, you must first understand  the basic structure of wire and cable is as follows:

1. Conductor: An object that conducts current, and the specifications of the wire and cable are represented by the cross section of the conductor.

2. Insulation: The insulating material is made of different thicknesses on the outside of the conductor according to the requirements of the withstand voltage level.

3. Protective layer: The part that protects the cable.

Second: the difference in market value of data line cost analysis

1. The price  of four core charging and sync USB lead is about 50% more than two-core charging lead.

2. The cable diameter of the wire core wire is also one of the influencing factors. For example, the frequently used 26AWG+28AWG data cable and the 24AWG+28AWG data cable are also very different. The main reason is that the core wire material is mostly tinned copper wire.  Tinned copper core wire is one of the main materials of wire.

3, Shielding layer is also one of the main reasons affecting the cost of data lines, data line manufacturers in order to save costs will use the powder data line, the general data line manufacturers will choose aluminum foil, so the selection of shielding layer is also one of the influencing factors.

Again: The recommended way for customers to purchase USB data lines is as follows:

1. If the function of the USB data cable only requires the charging function, you can select the two-core charging cable.

2. If the USB data cable transmits signals in the use environment, if the external signal has a small influence, you can choose to use the powder line to save costs.

3. If the environment used by the USB data cable receives the influence of electromagnetic waves, it is necessary to add a shielding layer because the current passing through the power cable is relatively large, and a magnetic field is generated around the current. In order not to affect other components, the shielding layer can be used.  The electromagnetic field is shielded inside the cable.  Because the current through the power cable is relatively large, a magnetic field is generated around the current. In order not to affect other components, the shielding layer can shield the electromagnetic field in the cable.

Now, you will know more about the price influence factors on the USB cable. In Sinodec Industrial Co., LTD., you can choose either USB charging cable or charging and sync cable as you want. We offer OEM service and wholesales service of our Micro USB cable, USB lightning cable and USB type C cable.
