Features of Power Towers
High-Strength Steel Structure
Power Towers are fabricated using Q235B or Q345B structural steel; the tower body maintains structural stability even under prolonged exposure to conductor tension and wind loads.
Corrosion-Resistant Galvanized Coating
The surface undergoes hot-dip galvanization, creating a dense protective zinc layer that effectively prevents oxidative corrosion and typically ensures a service life exceeding 30 years in outdoor environments.
Modular Design for Reduced Transport Costs
Featuring a segmented design (with individual sections ≤ 13m), the towers facilitate both sea and land transport, thereby lowering international logistics costs.
Bolted Connections for High Installation Efficiency
Utilizing standardized bolted connections eliminates the need for on-site welding, significantly shortening the overall construction cycle.
Quality Control
Raw Material Inspection: Prior to production, all Power Towers steel materials are inspected to verify that their material grade, thickness, and strength comply with Q235B or Q345B standards.
Cutting and Processing Inspection: After steel structural components have undergone cutting and drilling, they are inspected for dimensional accuracy and hole positioning tolerances.
Welding Quality Inspection: Welded joints are inspected to verify weld seam integrity and strength.
Dimensional Verification: Upon completion of component processing, critical structural dimensions are measured once again.
Trial Assembly Inspection: A sample assembly is conducted prior to shipment to confirm structural fit and compatibility.
Galvanization Inspection: The uniformity and surface quality of the galvanized coating are inspected.
Final Inspection: Shipment is arranged only after a final verification confirms the integrity of the structure, accessories, and packaging.
