Pole Top Brackets are core support components used in power and communication line installations, specifically designed to secure electrical cables, optical cables, and hardware to the tops of utility poles. Leveraging its own advanced production lines, Handan Jinmai Fastener Manufacturing Co., Ltd. offers a full range of customized pole top bracket solutions, meeting the load-bearing, weather-resistant, and insulation requirements of diverse scenarios. These products are widely used in power transmission and distribution systems, 5G base station construction, and rail transit, ensuring line stability and safety in complex environments.
1. High-strength, load-bearing design constructed from Q235 carbon steel/304 stainless steel, hot-dip galvanized (zinc layer thickness ≥ 86μm), with a tensile strength of 500MPa. It can withstand dynamic loads exceeding 300kg and is suitable for extreme climates.
2. Modular and flexible adaptability supports angle-adjustable installation (0°-45°), compatible with pole diameters from 150mm to 350mm, and includes standardized bolt holes for quick integration with various crossarms, insulators, and hardware.
3. Long-term corrosion protection certified by a 2000-hour salt spray test. The coating has strong adhesion and a service life exceeding 20 years in corrosive environments such as coastal areas and industrial pollution areas.
4. Customization services support custom designs based on drawings, including non-standard dimensions, hole layouts, and special coatings (such as epoxy spray). Design solutions are provided within 48 hours.
Handan Jinmai utilizes a four-step precision manufacturing process:
1. Mold Development: CAD modeling based on customer requirements, laser cutting of master molds;
2. Stamping: Integrated stamping using a 630T hydraulic press, with an accuracy of ≤0.1mm;
3. Welding Reinforcement: Robotic argon arc welding, achieving weld strength reaching 98% of the base material;
4. Surface Treatment: High-temperature hot-dip galvanizing → passivation and sealing → electrostatic spraying (optional).
