Many people can't tell the ground rod and the ground wire. In fact, there are a lot of mistakes. Today, Berlika Electric will introduce the difference between the ground rod and the ground wire.
The ground electrode we often say generally refers to the conductive element group in the earth or sea water, which can provide a low-impedance path between a point of the DC circuit and the earth, and the ability to continuously pass current within a certain time. That is, a conductor or a combination of several conductors buried in the ground to connect to the ground is called a ground electrode. The ground electrode is the electrode that makes full contact with the earth and realizes the connection with the earth. In the lightning protection project, multiple ground rods with a length of 2m and 1.5m are used, nailed to the bottom of a trench of 800mm deep, and then led out with stranded wire or bare copper wire.
The ground rod generally refers to an individual. The conductor composed of multiple ground rods is a ground electrode. In short, the ground electrode is a combination, the ground rod is an individual, and the ground electrode is a conductive group composed of multiple ground rods.
A ground wire is a wire that connects to the earth. Electricity is led to the earth by connecting an object to a ground rod; household electrical appliances can have a certain amount of static electricity in their enclosures due to poor insulation or a humid environment. In severe cases, electric shock can occur. To avoid accidents, connect a wire to the metal shell of the appliance and connect the other end of the wire to the ground. Once the appliance leaks, the ground wire will bring static electricity into the ground and discharge it.
In addition, their construction methods and application fields are the same. They are suitable for general environments and special environments with moisture, saline, acid soil, and chemically corrosive media. They are widely used in power plants, substations, transmission line poles, Lightning protection grounding, anti-static grounding, protection grounding, working grounding, etc. in communication base stations, airports, railways, subway stations, various high-rise buildings, microwave relay stations, network rooms, petrochemical plants, oil storage depots, etc.
