Kitchen wire should not be bought

There are a wide variety of building materials available. At present, there are many kinds of wires on the market, many specifications, and prices are chaotic. It is very difficult for consumers to choose. The average family uses 2.5 square millimeters and 4 square millimeters of copper wire, but the price of the same specification of a line, because the manufacturers are different, the price can be a difference of 20% to 30%, as to the quality of the pros and cons, the length is up to standard, Consumers are even more difficult to determine.

According to industry sources, the reason why the prices of wires are so different is due to the differences in the original production process. The main raw materials for producing wires are electrolytic copper, insulating materials and sheathing materials. At present, the raw material market has more than 70,000 yuan per ton of electrolytic copper, while the recycled copper is much cheaper; the gap between the quality of the insulating material and sheathing material and the defective product is even more disparate. In addition, the lack of length and inadequate insulation of the insulators also contribute to price differences. The length of each line, excellent products is 100 meters, while the defective product is only about 90 meters; the insulation content of excellent products accounted for 35% to 40%, while the defective products only 15%, through comparison, consumers can easily see that the finished product The difference in the sales price of electric wires is caused by the presence of tricky materials.

So, how to identify the advantages and disadvantages when buying a wire?

First, look to see whether there is a quality system certification; see whether the certificate is standardized; see if there is a factory name, site, inspection seal, production date; see if there is a trademark printed on the wire, specifications, voltage and so on. Also look at the cross section of the wire copper core, superior product copper color bright, soft color, otherwise it is defective.

The second is to try, it is desirable to use a wire head repeated bending by hand, all the soft feel, anti-fatigue strength, plastic or rubber feel elastic and wire insulation without cracks is superior products.
