What should pay attention to the purchase of wire and cable

Wire and cable products have a close relationship with the lives of consumers. Its quality and safety have a direct impact on the safety of people and property of consumers. Therefore, it is very important to purchase wires and cables correctly. Xingchengyi Cable Co., Ltd. reminds you that when you purchase wires and cables, authentication is the key. The method of identification is as follows:

1. Look at the "CCC" certification mark. Wire and cable products are national compulsory safety certification products. All production companies must obtain the “CCC” certification from the China Electrotechnical Products Certification Committee, and have “CCC” certification marks on the certificates of conformity or products.

2. Look at the inspection report. Wire and cable, as a product that affects personal and property safety, has long been listed as the focus of government supervision and inspection, and regular manufacturers are inspected by the supervisory department on a periodic basis. Therefore, the seller should be able to provide the inspection report of the quality inspection department, otherwise, the quality of the wire and cable products is lack of evidence.

3. Look at the packaging. All the regular enterprises that produce products that meet the national standards are very careful about the product packaging. Pay attention to the exquisite packaging, the printing should be clear, the model specifications, the name of the factory, and the complete site.

4. Look at appearance. Product appearance smooth and round, uniform color. The wire and cable enterprises whose products meet the requirements of the national standards shall strictly control the purchase of raw materials, production equipment, and production techniques in order to improve product quality and ensure that the products meet the requirements of the national standards. Therefore, the appearance of wire and cable products produced meets the requirements of the standard, smooth and round, uniform color. The appearance of fake and shoddy products is rough and dull. For the rubber-insulated flexible cable, the appearance is required to be round and the sheath, insulation, and conductor are not easily peeled off. The appearance of counterfeit and shoddy products is rough, the ellipticity is large, and the insulation strength of the sheath is low, and it can be torn by hand.

5. Look at the conductor. The conductor is shiny, and the DC resistance and conductor structure dimensions meet the requirements of national standards. The wire and cable products that meet the requirements of national standards, whether aluminum conductors or copper conductors, are all brighter and free from oil pollution. Therefore, the DC resistance of conductors is in full compliance with national standards, with good electrical conductivity and high safety.

6. Wire and cable length. The length is the main intuitive method of distinguishing between compliance with national standards and counterfeit and shoddy products. Do not try to buy cheap, cheap, buy the actual number of meters below its nominal number of wire and cable. The length must match the nominal meter number. The national regulations allow an error of ±0.5 meters per 100 meters.
