In recent years, on weak cable products fake and shoddy news emerge in endlessly, today we will look at the advantages and disadvantages of household wire how to distinguish, household wire and cable prices. How to distinguish the advantages and disadvantages of household wires?

1, the purchase of household wires, pay attention to the wire packaging plate as the volume of the China Electrical Products Certification Committee on the Great Wall logo and production license number, there is no quality system certification, certification is standardized, there is no factory name, site, production date and other content, whether the wire is printed with trademarks, specifications, voltage and other content; Look at the cross section of the copper core of the household wire, the general excellent copper color is bright, the color is soft, the copper core is yellow and red, the surface copper quality is better, if the yellow is white, it is low quality copper.

2. Take a wire head and bend it repeatedly by hand, if it feels soft, has good fatigue strength, plastic or rubber feels elastic, and there is no cracking phenomenon on the wire insulator, it is an excellent household wire; Intercept a section of insulation layer, see whether the core is located in the middle of the insulation layer, not in the middle of the surface process is not high, resulting in eccentricity, if the use of small power can be peaceful, once the power consumption is large, the thinner side is likely to be current breakdown.

3, look at the outer plastic of the household wire, choose the plastic skin shiny, fine texture, if you do not know the quality of the outer plastic material, it is best to use a lighter to ignite the test, if there is no open flame wire is excellent.

4, in the purchase of household wires, but also clear wire supplies. General lighting wire is best used between 1.5-2.5 square millimeters, and such wire matters choose flexible wire; If the air conditioning refrigerator and other high-power electrical appliances, the wire used is generally 2.5-4.0 square millimeters, and the lamp head is hard wire. If the use is too fine products, easy to make the wire heat and lead to short circuit, dangerous; If the wire used by the speaker will be special, it should be selected by high-purity copper as a conductor, or thin, the error of the wire length cannot exceed 5%, the cross-section diameter cannot exceed 0.2%, if it does not meet, it is a poor quality wire.

How to distinguish the advantages and disadvantages of the above household wire, the content of the price of household wire and cable is introduced here, what is not clear? I hope it was helpful.
