Bare aluminium conductors have several advantages over other types of conductors. Firstly, aluminium is lighter than copper, which makes it easier to handle and install. This is particularly important for overhead power lines, where the weight of the conductor can have a significant impact on the cost and feasibility of the project.
Secondly, aluminium has a higher conductivity-to-weight ratio than copper. This means that for a given weight, aluminium conductors can carry more current than copper conductors. This makes them more efficient in terms of power transmission.
However, bare aluminium conductors also have some disadvantages. One major drawback is their lower mechanical strength compared to copper conductors. This makes them more susceptible to sagging and stretching under the weight of their own span, especially in hot weather conditions. To address this issue, aluminium conductors are often reinforced with steel strands to improve their mechanical strength.
Another disadvantage is that aluminium has a higher resistance than copper, which can result in higher power losses and voltage drops. To mitigate this, aluminium conductors are typically designed with larger cross-sectional areas compared to copper conductors to compensate for the higher resistance.
Overall, bare aluminium conductors are widely used in electrical power transmission and distribution systems due to their cost-effectiveness, lightweight, and high conductivity-to-weight ratio. However, careful design and installation considerations are necessary to ensure their mechanical strength and minimize power losses.
