Inspection: use the fixed telephone to check the anti-counterfeiting mark. ? The products of the company use the digital anti-counterfeiting inquiry system of the anti-counterfeiting association of Wuhan Bureau of Quality and Technical Supervision. Please scrape off the gray coating of the anti-counterfeiting mark pasted on the product, call the toll-free number and enter the anti-counterfeiting number according to the prompt to check the authenticity (please note: each group of anti-counterfeiting numbers can only be queried once). ?
Question 2: Ask the company where to buy "He Fei" brand wire products. ?
Third, look:
1, a look at the material: "He Fei" brand wires are all made of high-quality insulation materials and sheath materials with special requirements such as PVC or polyethylene. Using this material, the color is bright and bright, and the inner and outer layers are the same. When customers buy, if they find that the color of the wire is dull, especially the color of the core insulation material of the white sheathed wire is inconsistent, and the sheath material is easy to tear, they can be initially judged as counterfeit products.
2. Look at the anti-counterfeiting logo: every wire produced by the company is affixed with the digital anti-counterfeiting logo of the Anti-counterfeiting Association of Wuhan Bureau of Quality and Technical Supervision.
3. Look at the logo: The shape and size of the "He Fei" trademark pattern on the "He Fei" brand wire certificate can be inquired online or to the industrial and commercial department. The font on the line of the certificate is clear and bright, otherwise it can be preliminarily judged as a counterfeit product.
Extended data
There are many kinds and specifications of wires, and the application range is wide, and the application voltage is 1kV and below. In the face of special occasions, new products are constantly derived, such as fire-resistant cables, flame-retardant cables, wdz, termite-proof cables, rat-proof cables, oil-resistant/cold-resistant/temperature-resistant/wear-resistant cables, medical/agricultural/mining cables, thin-walled cables and so on.
There are two kinds of electromagnetic wires: enameled wire and wound wire. Enamelled wire is made by coating insulating paint on bare copper wire. The insulating layer is thin and occupies a small volume. Widely used in various electrical appliances and instruments. The performance of enameled wires varies with the nature of insulating materials used. Winding wires mainly include yarn-covered wire, silk-covered wire, glass-covered wire, paper-covered wire and plastic film-covered wire, among which yarn-covered wire and silk-covered wire may be eliminated because of their poor temperature resistance and large occupation volume.
