[China Aluminum Industry Network] Nowadays, the connection of aluminum alloy cables in China is basically based on aluminum terminals or so-called alloy terminals that do not match the cable performance. The majority of electrical accidents occur at the connection points between the connection terminals and the cable conductors. The stability and reliability of the connection between the cable conductors and the connection terminals are crucial for the power system. Therefore, we must ensure that the advantages and value of aluminum alloy cable can be played and embodied. If aluminum alloy cables are used safely and without hidden dangers, aluminum alloy copper connectors with the same performance as aluminum alloy cables must be used.
If aluminum terminals or so-called alloy terminals that do not match the performance of aluminum alloy cables are used for connection, the aluminum material connecting the terminals or the so-called alloy whose performance is inconsistent with the cable may still have physical and mechanical performance defects and safety hazards, and the electrical terminals Performance and aluminum alloy cable conductor performance does not match, the use of large discounts and other issues still exist. This connection scheme is undoubtedly the wrong connection solution. This kind of erroneous connection solution will inevitably cause fatal hidden dangers to the user's transmission lines and also lay a hidden danger for the development of the industry.
As we all know, the connection application technology of aluminum alloy cable should be similar to the connection application technology of copper cable and aluminum cable. That is, the copper cable is connected to the copper nose, the aluminum cable is connected to the copper-aluminum transition terminal, and the aluminum alloy cable is connected to the aluminum alloy copper connection terminal whose performance is the same as that of the aluminum alloy cable. This is the correct cable connection solution.
