Take a closer look at the label printing samples. The address of the handwriting is unknown. Refers to the label on the label and the insulating cover. If there is a typo or a different shade of printing or the words are blurred, you must pay attention to it.
Insulate the skin with a hand, fade the color, remove the word quality. Refers to rubbing the insulation skin with your fingers. Some poorly insulated wire covers are easily discolored. This is especially true for red lines. After the rubbing, the skin color on the finger or the word printed on the skin is rubbed off. It is generally a poor quality line.
Then use a fingernail and a squatting line to draw down and peel off the skin. It refers to the use of fingernails and enamels to insulate the skin. It is generally a poor quality line that can be drawn down and smashed down.
Repeatedly bend the insulated wire and break it three to four times. It refers to the repeated bending of the insulated wire, and the poor quality of the insulating material of the poor quality wire is very poor. After the bending 3 to 4 times, the insulating layer will break.
Use fire to ignite the wire and leave the open flame for self-ignition. It refers to the ignition of the insulating layer, and it is the inferior line that can spontaneously ignite after leaving the open flame.
The core is usually made of aluminum and copper, and the color is dark and light. Refers to the color of the core. The color of the inferior line is dark and has no metallic luster.
Fine inner diameter and outer diameter, look at the weight of leather. It means that if the above six methods cannot be determined, the outer diameter and the core diameter of the insulated wire can also be measured. The allowable error is ±10%. If the measured value exceeds the allowable error, it is basically an inferior insulated wire.
