What distinguishes an overhead distribution system from an underground one?

The distinguishing factor between an overhead distribution system and an underground distribution system lies in their construction and installation methods. Overhead systems utilize elevated cables, which are strung between utility poles or towers above ground. This design allows for easier access for maintenance and repairs but can be more susceptible to weather-related issues such as ice, wind, or falling trees.

In contrast, underground systems consist of buried cables, which provide a more protected and stable setup, reducing the risks associated with environmental factors. However, while this installation method offers certain advantages, it is often more complex and can lead to higher costs and longer installation times.

Understanding this distinction is crucial for anyone working in electrical distribution, as it helps in assessing the appropriate technology for specific applications and environments. This knowledge is foundational in ensuring reliable and efficient distribution of electricity in various settings.
