Rural electrification projects (remote villages, agricultural zones)

Industrial parks (high-voltage power supply for factories)

Renewable energy integration (connecting wind farms, solar parks to grids)

Cross-regional high-voltage transmission lines
Connection Structure: Precision-machined flange connections (tolerance ≤0.5mm) ensure tight, shake-proof assembly.

Surface Protection: 85μm+ hot-dip galvanizing layer (tested via salt spray for 1000+ hours) prevents rust in coastal/humid areas.

Base Fixing: Reinforced concrete foundation brackets (with anti-slip design) enhance stability in soft soil.

Top Fittings: Customizable hardware (insulator mounts, cable clamps) compatible with global line standards.




Certifications: ISO9001, CE, UL, ANSI C136.10 (US), EN 50341 (EU).
Advanced Production: Automated welding lines, 3D scanning for dimensional accuracy, and ultrasonic flaw detection.


Testing: Every pole undergoes load-bearing tests (1.5x design load) and environmental simulation (extreme temperature/humidity cycles).
Shipping: Door-to-door service via sea (40ft containers) or land transport; poles are wrapped in anti-scratch film to avoid damage.
Customization: Tailor length, material, and fittings to your project’s needs (minimum order: 50 units).
Installation Support: Provide detailed manuals, video guides, or on-site technical teams (extra fee for on-site service).
Warranty: 10-year warranty for material defects; lifelong maintenance consulting.
