The Group's best-selling wire and cable guarantees electricity safety

Wire and cable is an indispensable material for users in the process of electricity consumption. The quality of the cable is directly related to electricity safety. Some illegal js shoddy, selling counterfeit wires, so many netizens deceived. In the year of 2009, the "panda wire" was adulterated and sold. In this small series on the most popular group of pandas in the above group as an example, to teach the majority of users how to identify the authenticity of the wire.

The following are three ways to really explain the authenticity of Panda wires.

The first method: First of all, the most intuitive is to look at the anti-counterfeit packaging stickers, the latest Panda wire stickers must be photographed, white bottom, green words, and there must be security telephone.

There are anti-counterfeiting marks on the panda wire package. After the tear-off mark, there are 15 passwords. Call the anti-counterfeit electricity on the package or 4008881861 “Security System Phone of Shanghai Quality and Technology Supervision Center” and verify it according to the voice prompts. In order to prevent counterfeiting, the password will be invalid after the panda wire is checked for authenticity.

Because the mimeograph is often printed on the plastic film of the package because of the temperature change, people can't see the numbers. Therefore, it is recommended that you attach a piece of plastic film to cut the security sticker, and then look it in reverse, so that it is convenient to check the authenticity.

The second method of identification: A panda on a single core line of authentic pandas is stamped with pandas per meter. There are words such as English brand logos instead of printed ones, which can be touched by hand.

The third way to identify: Look at the copper core of the wire.

1 Look at the material

In fact, there are many kinds of copper cores for electric wires, and the conductivity and hardness of different copper are different. For example, the copper wire of the red wire in the figure above is brass. Brass is a copper and zinc alloy. The hardness is good, but the conductivity is not. The copper wire of the blue wire is copper. The price of this material is yellow. Copper is higher, more conductive, and softer. It is an excellent raw material for making high-quality wires.

Copper qualified copper core wire copper core should be purple, shiny and soft to the touch. The shoddy copper core copper core is purple-black, yellowish or white, with many impurities, poor mechanical strength, and poor toughness. It will break when it is hardened, and the wire is often broken. When checking, everyone can bend the wire freely. It is best to look carefully at the copper core material. You just strip the wire 2cm, and then use a piece of white paper on the copper core slightly click, if there is a black material on the white paper, indicating more impurities in the copper core.

Qi Jiaxiao Tips:

The copper core material of high-quality electric wire is made of high-purity copper with good conductivity and good electrical conductivity. It has very good metallic luster. The inferior metallic wire has poor metallic luster and can be clearly distinguished with the naked eye. Copper materials used for poor quality copper wire contain high levels of impurities, high electrical resistance, poor electrical conductivity, high electrical power loss on the line, and serious heat generation on the wires. They can not ensure the safety of use, and can easily cause damage to household appliances due to short circuits. What's more serious is that Poor wires can easily cause fire and seriously endanger the safety of our lives and property.

2 see the cross section

When we buy electric wires, we must also look at the cross section. The insulation is thick and uniform. The copper core is exactly in the middle of the cross section. Such a wire can be regarded as a qualified and safe home wire.

Insufficient wire insulation seems to be very thick, in fact most are made of recycled plastic, over time, the insulation will age and leak.

Qi Jiaxiao Tip: The cross-sectional area of ​​the high-quality copper core is strictly in accordance with the national electrical standards to ensure its safe use under rated current strength and rated voltage. In order to reduce the production cost of inferior quality wires, the cross-sectional area of ​​its copper core does not meet the national electrician standard, and its actual rated current intensity and rated voltage are not achieved in practical use. Such wires can easily cause damage to electrical circuits when you use high-power appliances.

So how do we distinguish between genuine and false? Continue below to explain.

Common weak wires include: closed routes, network cables, telephone lines, audio cables, AV cables, VGA cables, audio cables, and so on.

Looking at the cross section is a good way to distinguish the wires. Some points to look at for weak wires include:

1, copper thickness

2, copper core location

3, the density of aluminum wire

4, the extent of tin foil package

5, the degree of toughness of the skin

To put it bluntly, it is to look at a material and workmanship. The counterfeit goods are fakes. It is impossible to be the same as the genuine craftsmanship. Therefore, if you look closely at the craftsmanship, you will find many clues. It's best to tear the wires apart so that you can see more clearly.

As for the authenticity of the weak wires, the method of distinguishing them from the strong wires is similar. The plastic texture of the skin must first be considered. After folding the wire and restoring it to its original shape, the poor quality wire will leave a crease that cannot disappear, which is very obvious, but the high-quality wires will not have such a phenomenon. This picture is a comparison chart after the true and false wires are bent. Obviously, the one below is false.

The use of wires

In general, a single core wire of 1.5 square wires is used for lighting; a single core wire of 2.5 square wires is used for sockets; a single core wire of 4 square wires is used for more than 3 air conditioners; a single core wire of 6 square wires is used for total progress. Line, two-color line for grounding. The new houses in the air-conditioning line are all in good order. Therefore, under normal circumstances, air-conditioning lines do not need to increase. The wire is recommended for pandas. In addition, Yuba's wires also use a socket cable, which is 2.5 square meters, with 4 squares of the best.
