What voltage range does a primary line typically fall within?

The voltage range for primary lines is typically within the range of 2.4kV to 34.5kV. Primary lines are used to distribute electricity over longer distances and connect substations to various endpoints, such as neighborhoods or large facilities. This range allows for efficient transmission, reducing both power loss and the size of conductors required compared to lower voltage lines.

The lower limit of 2.4kV is significant because it ensures that the power can effectively travel to the locations it serves while overcoming resistance in the lines. The upper limit of 34.5kV allows for sufficient power levels to be supplied to industrial and commercial users without needing additional transformation. Lines operating within this voltage range are essential for maintaining grid stability and efficiency.
