Electric wire and cable products and consumers of life have close relations, its quality, safety or not directly affects the general consumers' personal and property security, right to buy electric wire and cable is very important. Global trade nets to buy electric wire and cable, identification is the key. Identify the method is as follows:

1. See "CCC" the authentication marks. Electric wire and cable products is compulsory national security authentication products, all production enterprise must obtain China electric product certification committee authentication of the "CCC" certification, in conformance certificate or products are "CCC" authentication marks.

2. See inspection report. Cable as influence to the safety of person and property of products, has been listed as the government supervision and inspection, the regular production manufacturer focus on according to accept supervision department. Check cycle Therefore, vendors should be able to provide a quality inspection department of inspection report, otherwise, electric wire and cable products quality stand or fall is a lack of evidence.

3. See packaging. All production products meet the national standards of formal enterprise, the production of electric wire and cable pay great attention to packing. When the choose and buy note exquisite packaging, printing to clear, types and specifications, factory name, the site of factory is complete.

4. See appearance. Product appearance smooth rounder, the color and luster is even. Products comply with the national standard cable enterprise, in order to improve the product quality, ensure the products meet national standards, in the choose and buy, production equipment, raw materials production process strictly checks. So, the production of electric wire and cable products accord with standard, smooth appearance rounder, the color and luster is even. And fake and inferior product appearance rough dull. And for rubber insulation soft cable, requirements, and sheath, appearance roundness of the insulation, the conductor close not easy detachment. And fake and inferior products look rough, ellipse, sheath insulation intensity is low, with the hand can open.

5. See conductor. Conductor luster, dc resistance, the conductor structure size to the national standards. Comply with the national standard requirement of electric wire and cable products, whether aluminum material a conductor or copper conductor material, are bright, no pollution, thus the conductor dc resistance completely meet the national standards, has the good conductivity, high safety.

6. Quantity cable length. Length difference is standards and fake and inferior products mainly intuitive methods. When the choose and buy 10 million don't covet petty gain, the choose and buy the actual meters below the number of the number of nominal m wire and cable. Length must with nominal meters conform to number. State regulations allowed per m + 0.5 meters. Error
