Xingchengyi Cable Co., Ltd. reminds you that when buying wire and cable, identification is the key. The identification method is as follows:

1. View the CCC authentication identifier. Wire and cable products are national compulsory safety certification products, all production enterprises must obtain the China Electrical Products Certification Committee certification of the "CCC" certification, in the certificate or product there is a "CCC" certification mark.

2. Look at the inspection report. Wire and cable as a product affecting personal and property safety, has been listed as the focus of government supervision and inspection, regular manufacturers according to the periodic inspection of the supervision department. Therefore, the seller should be able to provide the inspection report of the quality inspection department, otherwise, the quality of wire and cable products is lack of basis.
