How to buy electronic cable?

All electrical equipment internal connecting lines are collectively referred to as "electronic lines", from the electrification, electronic lines with weak current, and strong wire has a great difference, the quality of electronic lines is very important, if the unqualified electronic lines will seriously affect the performance of electrical equipment, and even lead to safety accidents. So how to buy electronic cable? Let's get to know:

 

Electronic wire is divided into UL standard, 3C standard, VDE standard these three series, to AWG as a unit is generally UL standard, to the square section of the unit is generally 3C standard or VDE standard, domestic electronic wire manufacturers mainly to 3C or UL these two standards.

First, in the selection of products as far as possible to meet the standard requirements

 

Wire and cable in China is a national compulsory safety certification products, all production enterprises must obtain China Electrical products certification Committee certification "CCC" mark, and in the product and certificate marked with "CCC" certification mark. The export products should pay attention to THE UL standards of the United States and the ENVIRONMENTAL RoHS requirements of the European Union.

Two, the performance, specifications meet the requirements

 

In terms of performance and specifications, it is not easy to choose the one that suits your requirements among the numerous and complicated electronic wires. But from actual combat experience is not difficult, can summarize two steps, first, to learn from peers, learn from the practice of peers, can first launch the product. Second, constantly optimize peer practices so that your choices are more suitable for your products regardless of cost, performance and environmental requirements. Of course, you can also simplify the complex, directly consult our customer service, he will be very happy to provide his professional advice for you to choose.

 

3. The appearance of the product is qualified

 

Smooth and round appearance, uniform color. Products in line with the requirements of national standards of wire and cable enterprises, in order to improve product quality, ensure that products meet the requirements of national standards, in the purchase of raw materials, production equipment, production technology and other aspects of strict control. Therefore, the production of wire and cable products meet the standard appearance requirements: smooth round, uniform color. Electronic wire and counterfeit inferior product appearance rough matte. For rubber-insulated soft cables, the appearance should be rounded, and the sheath, insulation and conductor should be tight and not easy to peel off. And counterfeit inferior product appearance coarse, ellipticity is big, sheath insulation strength is low, can tear off with the hand.

 

The conductor resistance conforms to the standard.

 

The conductor is shiny, the dc resistance and the structure size of the conductor meet the requirements of national standards. In line with the requirements of the national standards of wire and cable products, whether aluminum conductor, or copper conductor are relatively bright, no oil, so the dc resistance of the conductor is fully in line with the national standards, with good conductivity, high safety.

 

Five, the length is accurate.

 

Length is the main intuitive way to distinguish between conforming to national standard requirements and counterfeit inferior products. Electronic wire in line with the national standard requirements of the length of wire and cable products in line with the national standard 100±0.5m (that is, to 100 meters as the standard, allowing error 0.5m), to protect the interests of consumers.
