1. Check the "CCC" certification mark. Wire and cable products are national compulsory safety certification products. All production enterprises must obtain the "CCC" certification certified by the China Electrotechnical Products Certification Committee, and have the "CCC" certification mark on the certificate or product.
2. Look at the inspection report. Wire and cable, as products affecting personal and property safety, has been listed as the focus of government supervision and inspection, and regular manufacturers are subject to inspection by the supervision department on a periodic basis.

4. Look at the appearance. The product has a smooth and round appearance and a uniform color. Wire and cable enterprises that meet the requirements of national standards, in order to improve product quality, to ensure that products meet the requirements of national standards, in the raw material purchase, production equipment, production processes and other aspects of strict control. Therefore, the appearance of the produced wire and cable products meets the standard requirements, smooth and round, and uniform in color. The fake and shoddy products have a rough and dull appearance. For the rubber insulated flexible cable, the appearance is required to be round, and the sheath, the insulation, and the conductor are not easily peeled off. The fake and shoddy products have a rough appearance, a large ovality, and a low insulation strength of the sheath, which can be torn by hand.
5. Look at the conductor. The conductor is shiny, and the DC resistance and conductor structure size meet the requirements of national standards. Wire and cable products that meet the requirements of national standards, whether it is aluminum conductor or copper conductor, are bright and oil-free. Therefore, the DC resistance of the conductor is in full compliance with national standards, with good electrical conductivity and high safety.
6. Measure the length of the wire and cable. Length is the main intuitive method to distinguish the requirements of national standards and counterfeit and shoddy products. When buying, don't be tempted to buy cheap wires and cables with actual meters below their nominal meters. The length must match the nominal number of meters. The state stipulates an allowable error of ±0.5 m per 100 m.
A salt lick is a deposit of mineral salts used by animals to supplement their nutrition, ensuring that they get enough minerals in their diets. A wide assortment of animals, primarily herbivores, use salt licks to get essential nutrients like calcium, magnesium, sodium, and zinc. When a saltlick appears, animals may travel to reach it, so the salt lick becomes a sort of rally point where lots of wildlife can be observed.
Farmers have historically provided salt licks for their cattle, horses, and other herbivores to encourage healthy Growth and development. Typically a salt lick in the form of a block is used in these circumstances, and the block may be mounted on a platform so that domesticated animals do not consume dirt from the ground along with the necessary salt. Salt blocks for farm animals can also be treated with medications, which may be convenient when someone needs to medicate shy animals, or a large group of animals.
