In order to obtain huge profits and disregard the interests of consumers, manufacturers of counterfeiting national standards for wires and cables produce inferior wire and cable products in large quantities, disrupting the wire and cable market and harming the interests of users. Therefore, it is very important to choose the correct wires and cables. What kind of products meet national standards?
1. Characteristics of wire and cable products that meet national standards
First, there is a certification mark. Since wire and cable products are closely related to the lives of consumers, their quality and safety directly affect the personal and property safety of consumers. Therefore, wire and cable products are national compulsory safety certification products. All manufacturing companies must obtain certification certified by the China Electrical Products Certification Commission, obtain the certification mark, and have the certification mark on the certificate or product.
Secondly, the packaging is exquisite. The packaging of wire and cable products is the same as other products. All large and medium-sized formal enterprises that produce products that meet national standards pay great attention to product packaging when producing wires and cables.
Thirdly, 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 wire and cable products produced meets the standard requirements of being smooth, round, and even in color. The appearance of fake and inferior products is rough and dull. 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. The counterfeit and inferior products have a rough appearance, large ovality, and low insulation strength of the sheath, which can be torn off by hand.
Fourth, the conductor is shiny, and the DC resistance and conductor structural dimensions meet national standards. For wire and cable products that meet the requirements of national standards, whether they are aluminum conductors or copper conductors, they are relatively bright and free of oil stains. Therefore, the DC resistance of the conductors fully complies with national standards, and they have good conductive properties and high safety.
Fifth, the length is accurate. Length is the main intuitive way to distinguish between products that meet national standards and fake and inferior products. The length of wire and cable products that meet the requirements of national standards complies with national standards (that is, based on meters, the allowable error is . meters), protecting the interests of consumers.
Sixth, the certificate must be clearly marked. The certification of wire and cable products that meet the requirements of national standards must be clearly printed. The certification logo, trademark, model specification, rated voltage, length, inspection, manufacturing date, certification number, execution standard, factory name, factory address, telephone number, etc. must be clearly marked. And it is consistent with the product, and some companies have written notices to users on the certificate to facilitate consumers to purchase and install it correctly.
