Copper-aluminum transition joints copper and aluminum wire
The chemical and physical properties of copper and aluminum are very large and should not be directly connected. However, copper-aluminum connections are inevitable. When connection is required, copper-aluminum transition Terminal clamps, copper-aluminum transition joints are generally used for direct connection.
Because the copper and aluminum metals have different electrochemical properties. If they are directly connected, a chemical battery is formed when water, carbon dioxide and other impurities are formed in the electrolyte. This is because aluminum tends to lose electrons and become a negative electrode. It is difficult for copper to lose electrons to become a positive electrode. Thus, an electromotive force of 1.69V is formed between the positive and negative electrodes, and a small current is passed through to corrode the aluminum wire, so-called electrification. corrosion. This will cause poor contact between copper and aluminum and increase the contact resistance. When there is current, it will increase the temperature of the joint, and the temperature will increase and accelerate the corrosion of the joint, increasing the contact resistance, causing a vicious circle until it burns and even causes a fire.
