Definition of wire and cable: Wire and cable is used to transmit electrical energy, transmit signals and achieve electromagnetic energy conversion electrical products.

Cable structure composition, the structural components of wire and cable products, in general, can be divided into wire, insulation, shielding and protective layer of these four main structural components as well as filling elements and bearing elements. According to the use requirements and application occasions of the product, some products have a very simple structure, only a structural part of the wire, such as overhead bare wire, overhead contact line wire, copper and aluminum busbar (bus);

In recent years, about the weak cable products fake and shoddy news emerge in an endless stream, many illegal manufacturers in the cable industry to pursue interests at the expense of product quality, so that the cable market is mixed, there is a lot of difficulty in consumer selection. As for the quality, whether the length is up to standard, consumers are more difficult to determine. In this year's 3.15, some unqualified cable products were ruthlessly exposed,

Domestic wire is basically divided into five categories: bare wire and bare conductor products, power cables, electrical equipment with wire and cable, communication cables and optical fiber, electromagnetic wire. These five types of wires in our daily life is the most commonly used bare wires and power cables, and most of the other is used for industry and communication, then these cables need to do what what testing certification? Let's take a look at it:

Contact with wire and cable people more or less know that there is a national standard line and non-standard line in the cable industry, many by the non-standard line caused by the tragic fire too numerous, it is not only the problem in the wire and cable industry, it is closely related to people's lives and property, today and you talk about the difference between non-standard wire and national standard wire. Non-standard wire: cables and wires for specific purposes that do not belong to the sp

As people have higher and higher requirements for speed, the number of devices and cables in the data center is gradually increasing, and the disorganized cables may cause network failures, so cable management has become one of the essential work in the data center. When it comes to cable management, we generally think of cable rack, distribution box and other products, presumably we are not unfamiliar with these products, however, this article will introduce a cost-effective cable manager - cab
