What is the minimum clearance required for a 22KV overhead line in areas subjected to truck traffic?

The minimum clearance required for a 22KV overhead line in areas subjected to truck traffic is 18.5 feet. This requirement is primarily established to ensure the safety of vehicles passing beneath power lines, particularly those that may have heights that vary significantly, such as large trucks. Maintaining a clearance of 18.5 feet helps to avoid accidental contact between overhead conductors and vehicles, which could lead to dangerous situations, including electrical shocks or outages.

This standard is informed by the potential risks associated with both the electrical system and the vehicular traffic in the area. In regions where vehicles of varying heights frequently operate, a higher clearance is necessitated. By adhering to this regulation, safety is enhanced for both the electrical infrastructure and the public using the roadways.
