Jiujin Electric Power’s D-iron Bracket with Secondary Swinging Clevis is engineered to address the need for articulated support in overhead power lines. The D-iron bracket provides a rigid base for mounting on poles, while the integrated swinging clevis allows controlled movement to absorb vibrations, wind-induced sway, and thermal expansion of conductors. Forged from high-tensile steel and protected with a heavy-duty hot-dip galvanized coating, this assembly ensures longevity in harsh environments. The design simplifies installation by combining two critical components into one reliable unit, reducing assembly time and potential points of failure. Manufactured in Hebei, China, with precision quality control, this fitting meets international standards for safety and performance in utility and telecommunication networks.
