Copper brightness is directly proportional to quality


1. Burning

Fake electric wires will burn quickly with fire, open flames and smoke. Real wires burn slowly with little or no smoke and no open flames.


There are signs on the insulation of the real wire, such as wire specifications, 3C certification, etc. and the handwriting is clear. Generally it can't be washed off with water, let alone

wipe it off. If you want to wash off the handwriting, you must use banana water to wash it off. There is a certificate of conformity in the electric coil. The certificate of conformity has

the manufacturer's address, telephone, 3C mark, quality system certification, voltage, wire model specifications, etc. On the fake line, there is no or missing.


The higher the copper brightness, the better the copper quality, and uniform brightness, shiny, no sense of layering. Qualified copper core wire copper core should be fuchsia, shiny, soft

to the touch. If you can peel off a small piece of plastic outer skin, look carefully at the copper wire inside, and touch the top of the copper wire with your palm, it should be flat,

without tingling, and feel softer.

Inferior copper core wires are purple black, yellowish or white, with many impurities, poor mechanical strength, and poor toughness. It will be broken with a little force, and the wire is

often broken. During the inspection, you just need to peel off the wire by 2CM, and then rub the copper core with a piece of white paper. If there is a black substance on the white paper,

it means that there are more impurities in the copper core. In addition, the shoddy wire insulation seems to be very thick. In fact, most of it is made of recycled plastic. Over time, the

insulation will age and leak electricity.

4.The length

It is not mandatory for the country to beat rice, but many manufacturers have also beaten rice. The rice that is beaten is not necessarily the national standard, but the general national

standard is generally not rice. Non-standard hitting meters is just a means. Generally, the length of national standard lines is 100 meters.

5.To try

It is advisable to repeatedly bend a wire end by hand. Anything that is soft to the touch, has good fatigue resistance, plastic or rubber has a large elasticity, and has no cracks on the

wire insulator is a superior product.
