FLAT ARRAY GROUNDING WIRE AND GROUNDING METHOD

In an electrical construction, grounding refers to a work for connecting a part of an electrical circuit or electrical equipment to the ground using a conductor.Since the ground maintains approximately the same potential, circuit parts connected to the ground through a low-resistance conductor may be considered to have a uniform potential value, and a conductor connecting an electric device to the ground is called a grounding conductor or grounding wire.The grounding wire is used with an insulating coating formed on the wire for the purpose of safety in processing. In the underground, the grounding wire is used in the form of a bare wire without the insulation coating for the purpose of close contact with the ground. The grounding wire can be used as a single wire when the size is small, however, if the size becomes large, several strands of wires are twisted and used in the form of a stranded wire.A conventional grounding wire installed in the ground is composed of a single stranded wire, so an inner surface of the stranded wire does not come into contact with the ground, so it is difficult to lower the grounding resistance value.Therefore, there are provided a flat array grounding wire and a grounding method using the same, in which the flat array grounding wire is configured to lower the grounding resistance value by greatly increasing the surface area in contact with the ground by arranging the grounding wires used for a grounding work in an electrical construction on a flat plane, so that the construction cost can be reduced as the grounding resistance value is lowered.
