Copper wire score 25 of the types of equipment needed in setting up the well, earth is made of copper metal with a purity of 99.9 per cent, so the electrical conductivity high, and can have a flow of electricity to a good pass. The application of these wires in the Earth System Transfer overload voltages generated surplus electronic devices to Page Earth, and ultimately to the ground. Weight of one meter of copper wire score 25 equal to 225 g, which is composed of 7 strands of copper twisted it. In place that should be well earthed will be drilled, there is a copper wire and plate earthing is essential because Should after digging the pit scratch a copper wire through a connection fastened to the page, boil, and eat, and then to the bottom of the Wells sent on the other hand, the other end of the wire, Earth, must be the electrical switchgear building connected, so in this case with the creation of the load current, add The voltages through wire Earth copper to the page, and then the land transferred, and risk of electrical shock disappears.
