Overhead pole brackets are core support components for power transmission and communications networks, designed specifically for securing ADSS/OPGW optical cables, electrical cables, and power lines. Handan Jinmai Fastener Manufacturing Co., Ltd., leveraging its in-house customized production capabilities, offers a comprehensive range of pole bracket solutions, covering the needs of various sectors, including power, communications, and railways. These brackets can be customized based on parameters such as pole diameter and load strength, and are compatible with various cement poles and metal towers ranging from Φ100mm to Φ400mm, ensuring stable installation of optical and electrical cables in complex environments.
1. High-strength and corrosion-resistant: Made from Q235 carbon steel or high-strength aluminum alloy, the base is hot-dip galvanized (zinc layer ≥ 86μm). It has passed the ISO1461 salt spray test and withstands Class C5 industrial corrosion environments, with a service life exceeding 30 years.
2. The adaptive structural design features a unique curved slot and multi-bolt locking system, accommodating slight arc differences in different pole diameters, eliminating installation stress and preventing cable wear.
3. Safety redundancy ensures a static load of ≥ 12kN and a dynamic wind load rating of Class 12 (referring to GB/T 2314 standard). Built-in anti-slip serrations prevent movement during operation.
1. Precision forging and forming utilizes an 800-ton hydraulic press to cold-forge the blank, ensuring seamless metal flow and increasing strength by 40%.
2. Intelligent galvanizing utilizes a controlled gradient temperature hot-dip process (445°C-465°C), resulting in a zinc layer density ≥500g/m² and Class 1 adhesion (ISO 1460).
3. Full dimensional testing utilizes a 3D coordinate measuring machine to verify aperture tolerances (±0.1mm) and supports short-circuit current capacity testing (i²t ≥ 50kA²s), meeting the DL/T 759-2001 standard for electrical hardware.
