52FT Three Section Flange Connection Octagonal Galvanized Electric Steel Pole 900KGF for 33KV
Yixing Hongxin Illumination Facilities Co., Ltd. offers the 52FT three-section flange-connection octagonal galvanized electric steel pole, rated at 900KGF for 33KV transmission and heavy-duty distribution applications. This pole represents the upper tier of Hongxin's standard distribution pole range, bridging the gap between distribution-class and transmission-class structures.
The three-section design with bolted flange connections enables efficient containerized shipping while maintaining full structural continuity at each flange interface. Manufactured from Q345B structural steel with 25+ years of specialized production expertise, every pole undergoes comprehensive quality control including robotic longitudinal welding, hot-dip galvanization to ISO 1461, and final dimensional verification against engineering drawings.
Key Features
- Three-Section Modular Design: Enables container-optimized shipping of tall poles that would otherwise require specialized break-bulk transport, dramatically reducing logistics costs for international projects.
- 900KGF High-Capacity Rating: Engineered for 33KV transmission lines, heavy-angle positions, and long-span crossings where elevated mechanical demands require robust structural capacity.
- Precision Flange Alignment: CNC-machined flange faces with tight flatness tolerances ensure uniform bolt preload distribution, preventing localized stress concentrations at the joint interface.
- Galvanized Fastener System: All flange bolts, nuts, and washers are hot-dip galvanized to match the pole coating specification, eliminating galvanic corrosion at dissimilar metal interfaces.
- Foundation Compatibility: Base plate dimensions and anchor bolt patterns are designed to interface with standard utility foundation designs, minimizing civil engineering costs for project development.
- Anti-Galloping Profile: The octagonal cross-section reduces aerodynamic instability compared to round poles, particularly important at heights above 40FT where wind speeds increase significantly with elevation.

Applications
The 52FT galvanized steel pole is designed for 33KV transmission feeder lines, substation interconnection corridors, and long-span river or highway crossing structures. Its three-section flange design makes it particularly suitable for international projects where containerized shipping is mandatory and on-site assembly resources are limited to basic lifting equipment.
The pole accommodates all standard 33KV line hardware including tension and suspension insulator strings, disconnect switches, and fiber optic ground wire attachments. Custom engineering for site-specific wind zones, ice loading maps, and seismic acceleration values is available through Hongxin's in-house structural engineering team.
Packaging & Quality Assurance
Each of the three pole sections is individually wrapped and the complete pole set is packed in steel-framed timber crates. Matched flange faces are protected with anti-corrosion compound during transit. Documentation includes Q345B mill certificates, flange machining reports, robotic weld logs, ISO 1461 galvanization measurements, and final assembly inspection records.
Third-party inspection by SGS or Bureau Veritas is available upon request. Standard warranty: 12 months. Minimum order: 10 pieces. Delivery: 30-45 days.
