Products are closely related to the lives of consumers. Its quality and safety directly affect the personal and property safety of consumers. Therefore, it is very important to purchase wires and cables correctly. When purchasing wires and cables, identification is key. The identification method is as follows:

Important cables and wires

1. Check the "CCC" certification mark. Wire and cable products are national compulsory safety certification products. All manufacturers must obtain the "CCC" certification certified by the China Electrical Products Certification Commission, and have the "CCC" certification mark on the certificate or product.

2. Read the inspection report. As products that affect personal and property safety, wires and cables have always been listed as the focus of government supervision and inspection, and regular manufacturers are subject to inspections by supervisory departments on a regular basis. Therefore, sellers should be able to provide inspection reports from the quality inspection department. Otherwise, there will be no basis for the quality of wire and cable products.

3. Look at the packaging. Any formal enterprise that produces products that meet national standards pays great attention to product packaging when producing wires and cables. When purchasing, pay attention to the exquisite packaging, clear printing, and complete model specifications, factory name, and factory address.

4. Look at the appearance. The product has a smooth and round appearance with uniform color. Wire and cable companies whose products meet the requirements of national standards, in order to improve product quality and ensure that products meet the requirements of national standards, strictly control the purchase of raw materials, production equipment, production processes, etc. Therefore, the appearance of the produced wire and cable products meets the standard requirements, is smooth and round, and has uniform color. Counterfeit products have a rough and dull appearance. For rubber-insulated flexible cables, the appearance is required to be round, and the sheath, insulation and conductor are tight and difficult to peel off. Counterfeit and shoddy products have a rough appearance, large ovality, and low insulation strength of the sheath, which can be torn apart by hand.

5. Look at the conductor. The conductor is shiny, and the DC resistance and conductor structural dimensions comply with national standards. Wire and cable products that meet the requirements of national standards, whether aluminum conductors or copper conductors, are relatively bright and free of oil stains. Therefore, the DC resistance of the conductors fully complies with national standards, has good electrical conductivity, and is highly safe.

6. Measure the length of wires and cables. Length is the main intuitive way to distinguish between products that meet national standards and fake and shoddy products. When purchasing, do not be greedy for cheap, and choose wires and cables whose actual meter number is lower than their nominal meter number. The length must match the nominal number of meters. The state stipulates that the allowable error is ±0.5 meters per 100 meters.
