What should we pay attention to when purchasing wires and cables
Jan 14, 2019

      Wire and cable products have a close relationship with the lives of consumers. Their quality and safety directly affect the personal and property safety of consumers. Therefore, it is very important to buy Wires and cables correctly. Wuhan Dingsheng Electric Power reminds us that identification is the key when buying wires and cables. The identification methods are as follows:

1. Check the CCC certification logo. Wire and cable products are compulsory national safety certification products. All production enterprises must obtain CCC certification from China Electrical Products Certification Committee, and have CCC certification mark on the certification or products.

2. Look at the inspection report. As a product affecting personal and property safety, wires and cables have always been listed as the focus of government supervision and inspection. Regular manufacturers receive periodic inspection by supervision departments. Therefore, vendors should be able to provide quality inspection department inspection reports, otherwise, the quality of wire and cable products is lack of basis.

3. Look at the packaging. All enterprises that produce products in accordance with the national standards pay great attention to product packaging. When choosing and purchasing, we should pay attention to exquisite packaging, clear printing, complete model specifications, factory name and site.

4. Look at the appearance. The product has smooth appearance and uniform color. In order to improve the quality of products and ensure that products meet the requirements of national standards, wire and cable enterprises that meet the requirements of national standards strictly control the selection of raw materials, production equipment and production process. Therefore, the appearance of the wire and cable products meets the standard requirements, smooth and round, uniform color. The appearance of fake and inferior products is rough and dull. For rubber insulated flexible cables, the appearance is round and the sheath, insulation and conductor are not easy to peel off. The fake and inferior products have rough appearance, large ovality and low insulation strength, so they can be torn open by hand.

5. Look at the conductor. The conductor is glossy, the DC resistance and the size of the conductor conform to the national standards. Wire and cable products that meet the requirements of national standards, whether aluminium conductor or copper conductor, are relatively bright, no oil pollution, so the DC resistance of conductor fully conforms to national standards, has good conductivity and high safety. DCZZ-10A DC resistance fast tester produced by Dingsheng Electric Power Company is an ideal device for measuring various inductive load resistance such as power transformer, contact resistance of low voltage switch, resistance of wire and cable or weld interface and DC resistance of high power inductance equipment. Its measuring speed is more than 100 times faster than that of bridge. DCZZ-10A DC resistance fast tester is used for AC power supply, which is suitable for field and harsh conditions. It is used in mountain forest conditions.

6. Measure the length of wire and cable. Length is the main intuitive method to distinguish fake and inferior products which meet the requirements of national standards. When choosing and purchasing, don't be greedy for cheapness. Choose wires and cables whose actual metre number is less than its nominal metre number. The length must correspond to the nominal metre number. The state stipulates that the allowable error per 100 meters is (+0.5 meters)
