What is the minimum clearance required for a 22kV overhead line over roads and streets subject to truck traffic?

16 feet

18.5 feet

For a 22kV overhead line over roads and streets that experience truck traffic, the minimum clearance requirement is set to ensure safety and adequate space to prevent any electrical hazards or interference. In this case, an 18.5-foot minimum clearance is stipulated based on industry standards and safety regulations.

This height is designed to accommodate various types of vehicles, including taller trucks, to minimize the risk of accidental contact with the overhead lines. The specific clearance requirement reflects a balance between safety, accessibility, and the necessity to prevent power outages or electrical shocks that could arise from lower hanging lines.

The other options, while representing heights that could be deemed safe in different contexts or for other voltages, do not meet the specific regulatory guidance related to 22kV lines over areas with truck traffic, which is specifically established as 18.5 feet to ensure the safety of both vehicles and the electrical infrastructure.
