What Are The Uses And Differences Between Tinned Copper Stranded Wire And Pure Copper Stranded Wire

Now copper stranded wire is all over the world, and the price of copper has also increased. Because of the change of copper price, it has brought a great impact on copper stranded wire. Let's talk about the direct relationship between galvanized copper and copper prices in detail.

The AC grounding system includes working grounding and protective grounding, and the products include grounding copper stranded wire products and tinned copper stranded wire products;

Low-voltage AC grounding protection methods: can be divided into three types: zero-connected system (Tn system), grounded system (TT system) and ungrounded system (IT system); DC grounding system:

According to different properties and uses, the direct grounding system can be divided into two types: working grounding and protective grounding.

1. Working grounding is used to protect the normal operation of communication equipment and DC communication power supply equipment;

2. The protective grounding is used to protect people and equipment; the grounding copper stranded wire is used for lightning protection. In the communication bureau, there are usually two types of lightning protection grounding:

3. One is a lightning rod lightning protection grounding device specially designed to protect buildings or antennas from lightning strikes, which are designed and installed by the building.

4. The other is to install lightning arresters and bury tinned copper stranded grounding devices in order to prevent lightning overvoltage from damaging communication equipment or power supply equipment. For example, the lower line of the high-voltage arrester is connected to the grounding device after being merged.
