In order to obtain huge profits, the producers of fake and inferior wire and cable disregarded the interests of vast consumers and mass-produced inferior wire and cable products, disturbing the wire and cable market and damaging the interests of the vast number of users. Therefore, the correct choice of wire and cable is very important, what kind of product is in line with national standards?
First, there is a "CCC" certification mark. Due to the close relationship between wire and cable products and the lives of consumers, the quality and safety of wire and cable products directly affect the personal and property safety of consumers. Therefore, the wire and cable products are national compulsory safety certification products, and all the manufacturing enterprises must obtain the "CCC" certification certified by China Electrotechnical Product Certification Committee, the "CCC" certification mark and the "CCC" certification mark on the certification or product.
Second, the packaging is beautiful. Wire and cable products, like other products and packaging, all products manufactured to meet the requirements of national standards of large and medium-sized enterprises, the production of wire and cable is very focused on product packaging.
Third, the product looks smooth and round, uniform color. Products in line with the requirements of national standards of wire and cable companies, in order to improve product quality and ensure that products meet the national standards, in the purchase of raw materials, production equipment, production processes, and other aspects. Therefore, the production of wire and cable products meet the standard appearance requirements: smooth and round, uniform color. The appearance of fake and inferior products matte dull. For rubber insulated flexible cable, the appearance of round, jacket, insulation, conductor is not easy to peel off. The fake low-quality products look rough, large ovality, sheath low dielectric strength, the hands can be torn off.
Fourth, the conductor is shiny, DC resistance, conductor structure size in line with national standards. Wire and cable products that meet the national standards, whether aluminum conductor or copper conductor are relatively bright, oil-free, so the DC resistance of the conductor in full compliance with national standards, has good conductivity, high safety.
Fifth, the length is accurate. Length is the difference between the national standard requirements and the main visual method of counterfeit inferior products. In line with the requirements of national standards for wire and cable products in line with the national standard length of 100 ± 0.5m (ie 100 meters as the standard error of 0.5 meters) to protect the interests of consumers.
Sixth, certificate of identity clearly. Meet the requirements of national standards of wire and cable product certification Clear print "CCC" certification mark, trademark, model specifications, rated voltage, length, inspection, manufacturing date, certification number, the implementation of standards, factory name, address, telephone, etc. clearly identified Chu, and with the product line, and some enterprises in the certificate marked "to the user" and other content for the majority of consumers the right to buy and install.
In addition, the purchase of wire and cable also need to consider its purpose, usually based on the size of the electrical power with the calculated wire current, then the current size of the optional wire size.
