The Pole Transformer Bracket securely mounts distribution transformers on utility poles, supporting single-phase and three-phase applications. Constructed from high-grade steel or ductile iron with hot-dipped galvanized coating per ASTM A153 standards, the bracket resists corrosion, moisture, and environmental stressors. Heavy-duty models support loads up to 15,000 pounds when properly installed, with individual positions handling 2,000 to 5,000 pounds depending on design.
The bracket accommodates pole diameters from 6 to 12 inches and transformers ranging from 3kVA to 333kVA, including single-phase models up to 167kVA. Common configurations support one to three transformers, with mounting hole spacings of 12 or 24 inches for National Electrical Manufacturers Association (NEMA) A or American National Standards Institute (ANSI) B lug types. Adjustable mounting points enable flexible configurations, while a jump-proof lip prevents accidental dislodging.
Installation uses provided hardware including machine bolts, nuts, and lockwashers to secure the bracket firmly. Some models allow ground-level assembly with transformers before hoisting via welded lifting eyes. The bracket meets industry standards including International Organization for Standardization (ISO) 9001, ASTM A153, and Rural Utilities Service (RUS) approval, ensuring certified compliance and reliable performance under operational stresses and diverse weather conditions.
