Made in China D-Type Iron Bracket

D-type iron brackets are indispensable connecting hardware in overhead power distribution lines. Primarily installed on crossarms, they suspend suspension insulators and bear the mechanical tension from conductors. They are widely used in 10kV rural power grid upgrades, urban power grid construction, and overseas overhead power engineering projects.

The product is made of high-quality carbon steel through a single stamping process, resulting in a stable overall structure. Thickened sections at stress points provide excellent resistance to bending and impact, allowing it to withstand alternating loads such as conductor tension and wind vibration over extended periods without easily deforming or cracking during operation. The entire structure undergoes hot-dip galvanizing, resulting in a uniform and dense zinc layer that meets the anti-corrosion standards for power fittings. This resists corrosion from harsh outdoor environments such as rain, humidity, and salt spray, effectively delaying steel corrosion, significantly extending the product's outdoor service life, and reducing subsequent line maintenance costs.

The product comes with a complete set of pins and cotter pins. After the pins are inserted, the cotter pins lock them in place, effectively preventing pins from falling off due to equipment vibration and ensuring the overall safety of the line. The U-shaped open frame structure, with pre-drilled standard mounting holes, is compatible with various specifications of suspension insulators and tension plates for assembly, making installation simple and convenient, and increasing on-site construction efficiency.

A wide range of product models and specifications are available to suit different crossarm sizes and insulator matching requirements. Customization based on customer drawings and samples is also supported. Strict quality control is maintained before shipment, including appearance, galvanized layer thickness, and mechanical load testing. These D-type iron supports are high-reliability basic fittings, and their stable performance has earned recognition from numerous domestic and international customers.
