How to Ensure the Safety and Service Life of Metal Poles in High-Voltage Backbone Transmission Lines?

2025-07-17

In high-voltage backbone transmission systems, the safety and longevity of metal poles are crucial to maintaining grid stability. The following strategies help ensure their long-term performance:

Use of High-Strength Materials
Select hot-rolled steel that meets ASTM or EN standards (e.g., ASTM A633 GR65) to enhance load-bearing capacity and fatigue resistance.
Professional Structural Design
Apply modeling and structural analysis based on PLS-CADD and ASCE standards to ensure safety under wind, seismic forces, and ice loads.
Hot-Dip Galvanized Corrosion Protection
Apply a zinc coating (≥85μm) through hot-dip galvanizing to protect against moisture, acid rain, and industrial atmosphere, extending service life to over 20 years.
Proper Site Selection and Foundation Engineering
Choose appropriate foundations based on geological surveys—such as rock-embedded or isolated foundations—to ensure pole stability in varied terrains.
Standardized Installation Procedures
Employ trained personnel for lifting and wiring to avoid structural stress or misalignment during installation.
Routine Inspection and Maintenance
Conduct regular inspections (annual or quarterly) to detect rust, loosened bolts, or coating damage; perform timely repairs or replacements.
Effective Lightning and Grounding Protection
Install proper grounding and lightning arresters to prevent lightning strikes from damaging the pole structure.
