The quality of the copper wire of the mobile phone data cable is closely related to 

the quality of the mobile phone data cable. How to judge the quality of the copper 

wire of the mobile phone data cable when purchasing the mobile phone data cable?

 Let's take a look at it.

Tips for judging the merits of the wire copper wire of the mobile phone data cable:

1. We look at whether the copper wire core is in the middle of the insulation layer. 

  Because if not centered, when there is a large current through, it is possible to put 

  the thin side of the electricity through, so the copper wire core is not centered copper

  wire cable is inferior cable.

2. Generally high-quality copper wire and cable are relatively soft, and the plastic on its

   surface is elastic. If we bend the copper wire and cable repeatedly by hand, 

   the corresponding  cracking phenomenon will not appear on the insulator, and 

   the plastic skin of the insulation layer is bright, and there will be no open flame 

   when lit.

3. To see whether its specifications are normal, in the relevant provisions, the length of 

    the copper wire and cable error can not exceed 5%, section diameter can not exceed 

    0.02%.  If you don't meet the rules at the time of purchase, don't buy it.

The skill of judging the advantages and disadvantages of the wire copper wire of the 

 mobile phone data cable is introduced to you here. If we can check the above three 

 points when buying the mobile phone data cable, we should be able to buy the 

 high-quality wire copper wire of the mobile phone data cable.
