What are the standard safety clearances and regulations for a 33kV overhead line?

2025-08-13

Safety is the top priority in overhead line construction. While specific regulations can vary by country and region (e.g., IEC, Indian Standards, local utility codes), the general principles for 33kV lines include:

  • Ground Clearance: There are minimum height requirements to ensure sufficient distance from the ground, buildings, and roads. A typical minimum clearance over a road is around 8.5 meters.

  • Clearance from Other Structures: Specific distances must be maintained from other power lines, communication cables, and buildings to prevent accidental contact.

  • Safety Devices: The use of danger plates, anti-climbing devices, and proper earthing arrangements on support structures is mandatory to protect the public and maintenance personnel.

Our tension stringing equipment and line tools are designed to facilitate the precise stringing and installation required to meet these stringent safety standards.
