Exothermic Welding Connection
There are several main objectives providing for well designed grounding system: personal safety, equipment protection signal reference quality,
return path for faults and surges and static dissipation.
In order to meet these objectives, grounding connection must maintain a low contact resistance often under adverse conditions for the expected lifetime of the grounding system. the connections in grounding network are subject to severe corrosion, high mechanical stress due to electromagnetic force and rapid thermal heating due to high current magnitude during fault conditionsExothermic Welding processKumwell Exothermic Welding process
is a molecular chemical reaction between copper oxide and aluminum, generates a tremendous superheat with molten metals reaching approximately temperatures of 4000°F (2600°C) The process used finely divided aluminum particles as the reducing agent with copper oxide to produce the following chemical reaction
3Cu0 + 2AI → 3 Cu + Al2
