Product Description
ASTM A123 Galvanized Step-Type 10m Medium-Voltage Distribution Steel Pole
Product Overview
The ESP-10M-ST-A123 is a cost-optimized step-type distribution pole designed for rapid deployment in 11kV-33kV overhead networks. Manufactured from Q235B structural steel with ASTM A123 hot-dip galvanization, this 10-meter pole features a two-section telescopic design with pre-drilled mounting holes that slash field installation time by up to 40%.
Key Features
- Step-Type Telescopic Design: Two-section construction with factory-controlled overlap joint ensures consistent structural performance and eliminates field cutting
- Pre-Drilled Mounting System: All cross-arm, insulator, and accessory holes CNC-drilled at factory per customer-approved GA drawings with ±1mm positional accuracy
- ASTM A123 Galvanization: Full-immersion hot-dip process coats interior and exterior surfaces uniformly, providing 86μm minimum zinc thickness for rural and semi-industrial environments
- Q235B Steel Economy: Proven carbon structural steel with excellent formability and galvanizing response, delivering reliable performance at competitive pricing
- Rapid Dispatch: Standard models maintained in inventory for 3-day sample shipment; production orders fulfilled in 7-15 working days

Applications
Budget-optimized solution for rural electrification programs, agricultural power distribution, secondary distribution spurs, temporary construction site power, and utility pole replacement projects where cost-per-kilometer is a primary consideration.
Installation Efficiency
Pre-drilled hole patterns are verified against customer-provided GA drawings using CMM (Coordinate Measuring Machine) inspection. Each pole ships with a matching hole schedule drawing for field crew reference. Typical 3-man crew can erect and outfit a complete pole within 2 hours using standard equipment.
