As a new type of power transmission material, aluminum alloy cables have gradually become the first choice for many power systems due to their lightness and economy. In order to ensure the installation quality and performance of aluminum alloy cables, the following are some key installation methods and precautions:

• Choose the appropriate cable model: The model selection of aluminum alloy cables needs to be determined according to the actual application scenario, especially in long-distance transmission, high current load and other occasions, it is necessary to select aluminum alloy cables with strong conductivity and durability.
• Check the cable before installation: Aluminum alloy cables need to be fully inspected before installation to confirm that the cable sheath is intact and check the electrical performance of the conductor.
• Avoid excessive bending: Compared with copper cables, aluminum alloy cables are relatively brittle, so excessive bending should be avoided during installation. The bending radius of aluminum alloy cables should meet the requirements of the specifications to avoid cable damage or unstable current transmission due to excessive bending.
• Joint treatment: The joint part of aluminum alloy cables requires special attention. Aluminum alloy conductors are relatively fragile and oxidation is prone to occur at the joints. Therefore, special aluminum alloy joints and connectors should be used in the joint part to ensure good contact and anti-oxidation treatment.
• Fixing and support: Aluminum alloy cables should be fixed with appropriate cable brackets or clamps during installation to avoid cable hanging or free swinging to prevent mechanical damage.
• Moisture-proof and anti-corrosion measures: Although aluminum alloy cables have good corrosion resistance, they still need to be treated with moisture-proof treatment in humid environments. Waterproof cable outer sheaths, sealed ends and other measures can be used to ensure the normal operation of cables in humid environments.

The correct installation of aluminum alloy cables can not only improve the efficiency of power transmission, but also effectively extend the service life of cables.
