Aluminum bus -bar and copper - aluminum transition joints

The conductive aluminium bus bar is a long conductor made of aluminum material called aluminum bus bar，have rectangular or chamfered (rounded) rectangle, which acts as a conductor to carry current and connect electrical equipment.
When producing the transformer outlet row, the copper bus-bar and the aluminum bus-bar are directly connected. Due to the difference of the two metal chemicals, when the air is wet, the electrochemical reaction occurs at the contact, which is commonly called “electro-corrosion”, which will cause the joint to be corroded. The contact resistance increases heat and eventually breaks due to overheating. Therefore, copper and aluminum can be directly connected indoors, and copper-aluminum transition joints should be used outdoors.
