Many countries require plug and cable products exported to their countries to pass safety certification and bear corresponding safety markings. Safety certification is mainly aimed at the requirements that electronic products may cause personal injury during use.The safety certification standards for plug wires vary from country to country, such as China's CCC standard. If you want to export your products to a certain country, you must pass the certification of another country.European certification: VDE, NF, IMQ, CEBEC, SEV, OVE, KEMA, SEMKO, DEMKO, FIMKO, NEMKO, TUV, GS, CE, etc;American certification: UL, CUL, CSA, ETL, CETL, FCC; The difference between UL and CUL is that UL is certified in the United States and CUL is certified in Canada;Asian certification: CQC, CCC, PSE, KC, PSB;Australian certification: SAA, C-TICK, A-TICK.
In daily life, plug power cords are widely used, and many industries may require power plugs. In most places where electricity can be used, plug power cords are used. From this, it can be seen that the purpose of plug power cords and their widespread use in every corner of our lives cannot be separated from plug power cords. Below is a brief introduction to the application of plug power cords in many key industries. Household appliances: What is close to our daily life is the plug and power cord on household appliances. Television sets, household refrigerators, fans, air conditioners, etc. all need to be used and must use a plug and power cord. Communication field: Usually, we also use plug power cords in various communication fields, such as telephones, wire receiving towers, aviation equipment, and so on. The various production equipment used in the factory and so on all require plug and power cables. In short, there is a saying: "Wherever electricity is needed, there is a plug and power cable
1、 If the quality certificate of the household appliance is qualified, then the quality of the power cord of the household appliance should also be inspected and there should be no major problems.2、 Check the cross-section of the wire, and the copper or aluminum core surface of the qualified product should have a metallic luster. Copper or aluminum with a black surface or a white surface indicates that it has been oxidized and is a non-conforming product.3、 The appearance of the power cord is qualified. The insulation (sheath) layer of the product is soft, flexible, and stretchable, and the surface layer is tight, smooth, without roughness, and has a pure glossiness. The surface of the insulation (sheath) layer should have clear and scratch resistant markings. Products produced with non-standard insulation materials have a transparent, brittle, and non ductile insulation layer.4、 The core of the power cord is made of pure copper raw material and has undergone strict wire drawing, annealing, and stranding. The surface should be bright, smooth, without burrs, with a flat stranding tightness, soft and resilient, and not easily broken.5、 Electrical appliances with different lengths of power cords require different lengths of power cords. Decoration owners should first understand the length of qualified power cords before purchasing, so that they can have a clear understanding when choosing electrical appliances.
