UL is the English Underwriter Laboratories Inc. for short, UL Safety Laboratory is the most authoritative in the United States, but also in the world engaged in safety testing and identification of the larger private institutions. UL will give a certification file number such as E172073.

In the daily work of many people should be involved in electrical things, in the current living conditions, a wide range of electronic equipment, the use of voltage is also different, there are high-voltage and low-voltage.

For newcomers who just contact home improvement work, everything is relatively unfamiliar, especially the wire and cable, because he can be divided into a variety of different types, can be used in different voltages and equipment.

In the general work, we have to use the wire is very much, and each wire has a different terminology, the variety is very much, many people are represented by the letters of the type of wire, such as bvvb wire, I think some people hear the word do not know what it means.

For newcomers who just contact home improvement work, everything is relatively unfamiliar, especially the wire and cable, because he can be divided into a variety of different types, can be used in different voltages and equipment.

In the wire and cable industry, there are thousands of different types of wire names. Of these thousands of wires, some are used all the time, while others depend only on unique applications. Our team will break down one of the more popular wiring products.

When we carry out the construction of the project for the majority of owners, the first thing to consider is safety, that in terms of safety shows that those bvvb2 copper core wire manufacturers are more suitable for the needs of the current project.

Whenever we often need to use wire and cable in the actual work, but there are places where the size of the power varies, we often hear that the difference in the load capacity of wire and cable will directly affect the transmission of electricity.

In today's wire and cable, cable insulation material is mainly pvc, the scientific name is polyvinyl chloride insulator, which leads to a wide variety of wire and cable products for different uses and environmental requirements.
