132 kV electrical line transmission towers are critical infrastructure components in modern power grids, designed to efficiently transmit high-voltage electricity across mid-to-long distances. These robust steel lattice or monopole structures support 132-kilovolt power lines, balancing structural stability with electrical safety standards. As a key voltage level in sub-transmission networks, 132 kV towers connect regional substations to distribution systems while minimizing energy losses.

1. High-Quality Hot-Dip Galvanization
Ensure thorough zinc coating (minimum 80-100 microns) for superior corrosion resistance, protecting the tower from harsh weather conditions.
2. Proper Material Selection
Use high-grade steel (e.g., ASTM A572 Grade 50) to enhance structural integrity and resistance to rust and fatigue.
3. Regular Inspections & Maintenance
Biannual visual checks for rust, cracks, or coating degradation.
Advanced NDT (Non-Destructive Testing) every 5 years to detect hidden corrosion.
4. Corrosion Prevention Strategies
Apply zinc-rich touch-up paint on damaged galvanized layers.
Install cathodic protection (sacrificial anodes) in highly corrosive environments.
5. Environmental Stress Mitigation
Strengthen structures in cyclone-prone regions with additional bracing.
Use anti-icing coatings in cold climates to avoid ice accumulation damage.
6. Proactive Repair & Refurbishment
Replace corroded bolts immediately with hot-dip galvanized alternatives.
Re-galvanize critical sections when necessary.
Junjiang 132KV hot-dip galvanized power towers are design to be high safety with high material utilization so as yo control the cost. And the raw materials are from the trusted steel suppliers which we’ve been collaborating with for decades. In the stage of welding, CO₂ welding and submerged arc auto welding are adopted in our fabrication process. Our steel towers meet all the strict standards above.
