How to identify the authenticity of Zheng Xing wire 40

1- When using, please measure the length of 100 meters and the diameter of the wire.

2- Counterfeit wires are 5-10 meters less per reel.

3- Counterfeit products have small cross-sections, 20%-40% larger resistance, and are easy to burn electrical appliances.

4-Identify the authenticity of Zhengxing cable, pay attention to the genuine anti-counterfeiting code, not repeated, not continuous; Each group of numbers can only be dialed once, and users can call 0371-67848319 for inquiries.

5- The customer dials 0371 67848319 and follow the prompts.

1.If it is genuine, it will inform you that the anti-counterfeiting code is correct, and inform the product specification and model. )2.If it is a fake, it will inform you that the anti-counterfeiting code does not exist, please beware of counterfeiting! )

The biggest disadvantage of the fake wire is that the number of meters is not enough, the 100 meters marked above, you measure its one meter, only about 85cm, a plate is about 15 meters less, and the line inside is too thin. It is best to take a scale to buy wires I know that the square Zheng 3 factory BV line is full of more than 2 catties, but it can also be used, and the fake wires are generally acquiesced by electricians Even the manufacturers do not care. It's best not to let the electrician wrap the line for your own home improvement line, and buy the wire yourself The price of the real line and the false line is about 50% wrong.

There is no real or false wire, it is made of the same material. That's true and that's fake, it's just a matter of trademarks.

Regardless of whether it is true or false, just look at the quality!

It is recommended to go to the wire and cable industry ** "cable 315" above the more products and information, professional cable industry, procurement personnel often look for products, to improve the company's visibility and promote the product effect is better!

It has to be golden, professional.

We can't buy the real thing.

Now you can't look at the brand, the key is quality.

If the fruit is a real cable, the national standard, the quality is stable. The fake Zheng Xing card is too leaky, and there are many friends, so you should pay attention to the difference between sleepy reeds.

A cable is usually a rope-like cable consisting of at least two stranded wires or groups of wires, each insulated from each other, and often twisted around a center to form a highly insulating covering.

A cable is usually a rope-like cable consisting of at least two stranded wires or groups of wires, each insulated from each other, and often twisted around a center to form a highly insulating covering. Most of them are erected in the air or installed underground or underwater, and are used for telecommunications or power transmission. In 1832, the Russian veteran officer Schullinger buried the telegraph line in the ground, and the six wires were insulated with rubber from each other and placed in glass tubes, which was the world's first underground cable.

An insulated wire consisting of one or more conductive cores insulated from each other in a sealed jacket. It can be covered with a protective cover for the transmission, distribution of electrical energy or transmission of electrical signals. The main difference between it and ordinary wires is that the cable size is larger and the structure is more complex.

The cable is mainly composed of the following 4 parts. Conductive core: Made of a high conductivity material (copper or aluminum).

Depending on the softness of the cable under the conditions of use, each core may be made up of a single conductor or multiple conductors stranded. Insulation: The insulating material used as a cable should have high insulation resistance, high breakdown electric field strength, low dielectric loss and low dielectric constant.

The commonly used insulating materials in cables are oil-impregnated paper, polyvinyl chloride, polyethylene, cross-linked polyethylene, eraser, etc. Cables are often classified by insulating materials, such as oil-impregnated paper insulated cables, PVC cables, cross-linked polyethylene cables, etc. Sealing sheath:

Protects the insulated core from machinery, moisture, moisture, chemicals, light, etc. For insulation that is susceptible to moisture, lead or aluminum extruded sealing sheaths are generally used. Protective overlay:

It is used to protect the sealing sheath from mechanical damage. Generally, galvanized steel strip, steel wire or copper strip and copper wire are used as armor to wrap around the sheath (called armored cable), and the armor layer plays the role of electric field shielding and preventing external electromagnetic interference at the same time. In order to avoid the corrosion of steel strips and steel wires by the surrounding media, they are generally coated with asphalt or wrapped with an impregnated jute layer or extruded polyethylene and vinyl chloride sleeves.

Cables can be divided into power cables, communication cables and control cables according to their use. Compared with overhead lines, the advantages of cables are that the insulation distance between the lines is small, the space occupied is small, the underground laying does not occupy the space above the ground, it is not affected by the surrounding environmental pollution, the power transmission reliability is high, and the interference to personal safety and the surrounding environment is small. However, the cost is high, the construction and maintenance are more troublesome, and the manufacturing is more complicated.

Therefore, cables are mostly used in densely populated and grid-dense areas and congested places; In the river, river and seabed laying, the use of long-span overhead lines can be avoided. Cables can also be used where there is a need to avoid communication interference from overhead lines, as well as where aesthetics are a concern or where exposure to targets is a concern.
