Wire and cable industry in China has become second only to the automotive industry. In the domestic market share has reached 90%, and in the world, China's total production of wires and cables has exceeded the United States. At present, China has become a big producer of wires and cables. With the rapid development of cable, the number of enterprises is increasing. Due to the good development of China, all countries in the world have focused on the Chinese market. Since the implementation of reform and opening up, the huge power of Chinese people has shocked the world in just a few decades. Let the world have a new view on China.

 

The difference between power cable and control cable is that power cable is used for transmission and distribution through the main part of power system. The control cable is a power supply connection line that directly transmits electric energy from a distribution point of the power system to all kinds of equipment that need electricity. The cables we use in our daily life are generally divided into high voltage and low voltage. If you are using a high voltage cable, you will find that there is a layer of resin like filler inside the cable, which will play an insulating role. In the high voltage cable, this is an essential part. On the contrary, there is no such thing in the low-voltage cable, but it will be wrapped with something similar to ribbon. This is to fix each core in the cable and fill its own gap.

 

Because the current passing through the power cable is large, a magnetic field will be generated around the current. In order that the rest of the parts can continue to be used, an electromagnetic field shield is usually added outside. The main thing is to play a safe role. Modern society cannot do without electricity. People use electricity all the time, so we should know more about it.

 

Control cables will be used in coal mining enterprises and energy transportation. It usually works between 70 and 90 degrees centigrade. It is mainly used in the field of electric power. But also can achieve moisture-proof, anti-corrosion effect, but also can effectively avoid damage. The rated voltage of power cable will be larger than that of control cable, so when the power cable and control cable of the same specification are in production, the insulation and protective sleeve of power cable are thicker than that of control cable.
