Cable is a kind of blood vessels and central nervous system, from power installation projects, traffic lines, urban traffic, communications, construction projects to general home decoration must use wire and cable. However, in the long-term use of the cable, it will be damaged by many factors, leading to the aging of raw materials, resulting in a decline in product performance, very much the aging of cable sheath raw materials may lead to common problems, and even lead to safety accidents. Therefore, in the selection of wire and cable, we should try to choose high-quality cables, the full performance of high-quality wire and cable is undoubtedly stronger, but also can use longer life, so how should we choose high-quality wire and cable?

1. Query the "CCC" authentication mark.

Cable products are national mandatory certification products, and all manufacturing enterprises have obtained the "CCC" certification, certificate or product certified by the China Welder Product Certification Committee as far as possible.

2. Read the inspection report.

As a product that endangers personal safety, capital and property safety, cables have always been listed as the top priority of government supervision, and manufacturers accept corporate supervision and inspection on a regular basis. Therefore, the distributor should be able to provide the inspection report issued by the product quality inspection department, otherwise, the quality of wire and cable products is lack of basis.

3. Look at the packaging

Where the production and processing products meet the national industry standards of reliable enterprises, the production and processing of cables are very focused on product packaging. Select good packaging, printing and packaging to be clear, model specifications, company name, manufacturing location is complete.

4. Look at the surface

The appearance of high-quality cable products meets the standard requirements, smooth, uniform color and bright. Compared with counterfeit products, the appearance of the product has a raised dimness. And rubber cable sheath soft cable, requiring good appearance gloss, wire sheath, cable sheath, conductor tight connection is not easy to take off. The appearance of the counterfeit products is convex, the ellipse is large, the protective wire set is low, and the force can be torn.

5. Look at the conductor

The wire is smooth... The conductor structure and model meet the requirements of national industrial standards. In order to make the insulation material between the wire and the wire more bright, oil-free, fully in line with the national industry standards, its electrical conductivity is good, high safety, in line with the national industry standards, with good electrical conductivity, good safety.

6. Measure the cable length.

Length is an important concrete method to distinguish products that meet the requirements of national industrial standards. When buying, do not be greedy for small bargains, and buy wires and cables with actual meters lower than their tolerance meters. This length must be the same as the tolerance meter. The allowable error is ±0.5 meters per 100 meters.
