as a concealed project of decoration, the materials used in hydropower also have strict requirements. Ground wire is a kind of circuit material, which plays a certain protective role. What is the specification of the grounding wire? Today, let's take a look at the specification of grounding wire through the following content introduction

specification of grounding wire

as the name suggests, the grounding wire is actually a line connected with the earth. In short, it can also be called a safe return line. When there is an emergency danger, the existing high voltage is directly converted to the earth, which can be said to be a safe line. As for the specification of grounding wire, the national power industry has strict requirements. In order to avoid accidental high-voltage hazards on power outage machinery and equipment and lines, it is uniformly stipulated that the specification of grounding wire should be more than 25mm 2, and the product is made of bare copper flexible wire

function of grounding wire

1 In many household appliances, due to the poor performance of the products and the long-term use in a humid environment, it is easy for the shell of household appliances to produce a certain amount of electrostatic effect. If the situation is serious, it is easy to have potential electric shock. In order to solve this problem, a ground wire is usually connected to the shell of these household appliances, and the other end is connected to the ground. Once there is leakage, the ground wire will immediately release static electricity to the ground, effectively avoiding potential safety hazards

2. The grounding wire is also very helpful to the electric soldering iron welding circuit, because the electric soldering iron is charged and it is easy to damage the circuit in the appliance, so the appliance maintenance personnel will connect the grounding wire. In addition, many people in the computer industry tend to ignore the connection of the ground wire for the host. In fact, connecting a ground wire can prevent the crash to a certain extent

3. For the communication industry, the grounding wire is also frequently used, because the communication line voltage is not high, it is easy to appear electromagnetic interference to affect the transmission. Although all shielding layers of the communication line can block electromagnetic interference, if connected to the ground, the generated voltage will be released to the ground, making the communication more normal and avoiding external interference to the signal in the communication. However, after the work is completed, the ground wire should be removed in time to avoid damaging the equipment and affecting the use

color of ground wire

ground wire is to connect one end of the line to the shell of the appliance and the other end to the earth, effectively reducing the occurrence of potential electric shock. In the circuit used in the decoration space, the live line is often represented by yellow, and the zero line is represented by blue line. However, the yellow green line is the ground line

about the specification of grounding wire, I'll briefly introduce it here. I hope it will be helpful to you. If you want to know more about wires, you can pay attention to the information, and more wonderful content is waiting for you
