Zhengzhou Wubai Cable and Wire Co.,Ltd

At present, there are quite a lot of various cable products such as photovoltaic cables and power cables on the market. At the same time, this also represents a wide variety of cable brands and types on the market. Therefore, if you want to choose a more suitable cable product, it is not only a matter of money, but also requires us to understand some relevant skills for purchasing cable products.

 
 Choosing the correct cable model is to ensure the safety of power transmission. If the wrong or bad selection is made, it will not be said about wasting resources, and it is easy to cause safety accidents. This is the basis for ensuring the safety of electricity use. If the wrong model is selected, it will not only waste resources Resources are also easy to cause safety accidents. For example, some households have a large electricity load, but choose small wires, which are easy to cause safety accidents.

Of course, we must pay special attention to the practicality of the product to choose which model of the product. It is only for ordinary households, and the wire is better. If it is used in construction projects, the cable should be selected.

It should be noted that the choice of cable products depends not only on the price, but also on whether the quality of the product meets the national standards, so as to avoid unnecessary trouble. Of course, the quality of our cable products is still good, so the specific standards for purchasing wires and cables what is it?

Look at the outer packaging: the appearance of the general national standard line is still relatively good, both in terms of vision and feel, it is not bad. Of course, the national standard cable can also be detected. It can burn with fire. If it goes out within 5s after leaving and has a certain flame retardant function, it can be regarded as a national standard cable.

Look at the inner core of the cable: copper inner core material, the higher the brightness, the better the copper. Plus even luminosity and sheen with no layering. The national standard requires the use of oxygen-free copper for its core. If it is non-standard, such as black rod copper, there may be hidden dangers of accidents. However, the thickness of the inner core of the cable has certain requirements in the national standard, but it is not particularly strict. But the error is generally small.

Look at the line length: The country does not specifically require rice milling, but many manufacturers do. However, the general national standard cable products generally do not have meters, and the meters produced are not necessarily national standard. Non-national standard rice harvesting is just a means. Of course, the state stipulates that relevant signs must be marked on the wires. At this time, the user should make relevant markings as required.
