The life of an earthing network is determined not by the conductors but by the connections.<\/strong> In a system buried underground the conductor can go on doing its job for decades; but a single connection that has loosened or corroded ends the electrical continuity of the whole network. What is more, this fault is invisible to the eye \u2014 it can only be found by measurement, and often only once it is already too late. <\/p>

Exothermic welding (thermite welding) joins two conductors with molten copper, making them a single piece at molecular level. The resulting connection has the same current-carrying capacity as the conductor itself and is sealed against corrosion underground. This is why it is our preferred method for permanent earthing connections. <\/p>

At Y\u0131lkomer we supply exothermic welding system equipment and carry out the application with our specialist team.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
