1. Power Distribution

One of the primary uses of Bare Stranded Conductors is in power distribution systems. These conductors are widely used for overhead power lines due to their high conductivity and lower weight compared to solid conductors. For instance, utilities often choose bare aluminum conductors for their transmission lines because they offer excellent resistance to corrosion and are lightweight, making them easier to install and maintain.

Recommendation: When selecting a Bare Stranded Conductor for power distribution, consider the tensile strength and environmental conditions of your installation site. High tensile strength is vital for overhead lines to withstand wind and ice loading.

2. Grounding Applications

Grounding is another vital application for Bare Stranded Conductors. These conductors are used in grounding systems to ensure the safety of electrical installations by providing a low-resistance path for fault currents. The flexibility and durability of bare stranded configurations make them ideal for adapting to various environmental settings.

Example: In solar power installations, bare stranded conductors are often employed in the grounding system to protect against lightning strikes and electrical surges.

Recommendation: Ensure the bare stranded conductor selected has appropriate insulation and is correctly sized to handle the expected fault currents. Regular maintenance checks are crucial to ensure the conductor remains effective over time.

3. Industrial Applications

Bare Stranded Conductors are also prevalent in the industrial sector, particularly in machinery and equipment where flexibility is crucial. They are utilized in transport systems, such as cable cars and cranes, where the conductor must bend and move without losing electrical connectivity.
