Hot-Dip Galvanized Tapered Octagonal 11kV Distribution Steel Electric Pole 12m Q345B ASTM A123

Product Overview

The ESP-11kV-12M-OCT is a premium tapered octagonal steel pole engineered for 11kV medium-voltage distribution networks. Fabricated from high-strength Q345B steel and finished with ASTM A123 hot-dip galvanization, this 12-meter pole delivers exceptional structural integrity and decades of corrosion-free service in diverse environmental conditions.

Key Features

• Tapered Octagonal Profile: Optimized wind load distribution with reduced material weight compared to round poles of equivalent strength
• ASTM A123 Galvanization: Minimum 86μm zinc coating (610g/m²) providing comprehensive cathodic protection against rust and atmospheric corrosion
• Q345B High-Strength Steel: Yield strength ≥345 MPa, ensuring reliable performance under heavy conductor and equipment loading
• Slip-Joint Assembly: Precision-engineered overlap joints with 1.5* diameter embedment for rapid on-site erection
• Pre-Drilled Mounting Holes: Factory-drilled per customer specifications for cross-arms, insulators, and accessories

Technical Specifications

Applications

Ideal for 11kV overhead distribution lines, rural electrification projects, industrial park power supply, and utility grid extensions. Compatible with porcelain and polymer insulators, fused cutouts, and lightning arresters.

Quality Assurance

Every pole undergoes: (1) 100% ultrasonic weld inspection, (2) dimensional tolerance verification per GB/T 2694, (3) zinc coating thickness testing with magnetic gauge, (4) straightness check within 0.2% of total length, (5) full traceability with heat number documentation.

Customization Options

Custom heights (9m-18m), alternative steel grades (Q235B, Q420B, ASTM A572 Gr.50), powder topcoat colors, specific hole patterns for hardware mounting, and integrated ladder clips available upon request. Contact our engineering team for project-specific designs.
