Multiple Drop Wire Cross-arm Brackets are indispensable precision components in the construction of power transmission and distribution systems and communication networks, and are designed for high-altitude erection scenarios such as utility poles and communication towers. The product uses a modular structure to achieve synchronous fixation and support of multiple cables, which can effectively optimize line layout, improve power transmission stability and optical cable communication efficiency, and is widely used in engineering fields such as urban and rural power grid transformation and 5G base station construction.
1. High-strength material
Made of Q235 carbon steel or customized alloy, formed by precision stamping and welding process, with a tensile strength of ≥400MPa, it can withstand extreme wind loads and mechanical stress.
2. Anti-corrosion treatment
The surface is hot-dip galvanized (average zinc layer thickness ≥ 85μm), in line with ASTM A123 standards, with salt spray resistance of more than 1000 hours, suitable for high-corrosion environments such as coastal areas and industrial areas.
3. Modular design
Supports horizontal expansion installation, a single bracket can integrate 2-6 line positions, equipped with an adjustable card slot design, compatible with cables of different diameters (Φ8-25mm), simplifying the line expansion and maintenance process.
4. Convenient installation
Pre-set standardized installation holes, suitable for M12-M16 bolts, support vertical/horizontal multi-angle fixing, significantly reducing construction time and labor costs.

1. Material selection: Select low-carbon steel plates, and the material composition is tested by spectrometer to meet the standards;
2. Precision stamping: CNC hydraulic press completes the punching and bending of the main structure, with an error of ≤0.2mm;
3. Automatic welding: CO₂ gas shielded welding process is adopted to ensure the strength and appearance consistency of the weld;
4. Surface treatment: The fully automatic galvanizing line completes the processes of pickling, plating assistance, hot dip plating, etc.;
5. Quality inspection: Pass the triple quality inspection of three-coordinate measuring instrument, coating thickness gauge and tensile testing machine.
