Identify the quality of the power cord and the use of the plug power cord Power cord

is a daily necessities in people’s career and tasks, especially for home decoration, office and production lighting, power cord quality is safe and serious. The attack of a lot of fire is because power cord is aging, equipment is unreasonable, perhaps use low quality low quality power cord to form, therefore, consumer must polish eyes when buying wire, careful identification, nip in the bud. The country requires the use of copper core insulated wire in new houses, office and production lighting, but the same is copper wire, there are also inferior copper wire, the copper core selection is recycled copper, recycled copper contains a lot of impurities, some inferior copper wire conductive function is even not as good as the iron wire, easy to stimulate electrical accidents. Current, the wire brand on the market is much, the price is chaotic, when consumer selection is very difficult. Single on the family decorate, office and production lighting commonly used 2.5 square millimeter and 4 square millimeter two kinds of copper core wire price, the coil of power cord of the same specification, as a result of manufacturer disagreement, price difference 10% – -20%, even bigger, as to quality stand or fall, length can reach the standard, consumer is difficult to conclude more. The reason why the price difference of the power cord is very big is because of the difference of the original data used in the production process. The main original materials of the production power cord are electrolytic copper, insulation data and insulation sheath material. At present, the electrolytic copper per ton on the market is 49,000 yuan, while the recycled miscellaneous copper is only 33,000 yuan per ton; the price of quality products of original insulation data and sheath material is 9000 yuan-10000 yuan per ton, and the price of defective products may be only 5000 yuan 6000 yuan per ton, the price difference is different. In addition, the lack of length, the insulator glue content is not enough, is also the main reason for the price difference. The length of each coil wire, excellent product (national standard) is 100 meters ± 0.5 meters, also be in at least 99.5 meters / roll, and inferior product wants 95 meters only, and so-called be national standard, some even want 80 meters cabinet only even. After comparison, it is not difficult for consumers to see that the difference in the sales price of the finished power line is the gap on the material.
