What is the shielding angle for 400kv transmission line tower?

The shielding angle for a 400 kV transmission line tower typically ranges from 30 to 45 degrees. This angle is designed to protect the line from lightning strikes by ensuring that the electric field around the conductor is sufficiently reduced. The exact angle may vary based on factors such as local terrain, weather conditions, and specific design standards. Proper shielding is crucial for maintaining the reliability and safety of high-voltage transmission systems.
