A pole top bracket mounts and secures equipment such as post-type insulators at the top of utility poles in overhead power line construction. The bracket features an open neck design allowing wrench movement during installation, an open bottom slot for easier assembly and removal, and an offset configuration providing adequate insulator clearance from the pole. Models are rated for voltage classes including 35 KV, 55 KV, 69 KV, and 88 KV, and accommodate line post studs with 5/8 inch or 3/4 inch diameters.
Construction typically uses ductile iron conforming to American Society for Testing and Materials (ASTM) A-536 or aluminum alloy, finished with hot-dip galvanized coating per ASTM A-153 for corrosion resistance in outdoor environments. Mounting bolt diameters range from 5/8 inch to 3/4 inch, with weights from approximately 3.4 to over 12 pounds depending on the model. Dimensions include lengths up to 24-9/16 inches and widths around 3.875 inches, with specific versions designed for different pole diameters and load capacities up to 200 pounds.
Installation involves through bolts securing the bracket against flat pole gains, with slotted mounting holes accommodating variations in bolt spacing such as 203 millimeters center to center vertical spacing. The brackets support crossarms, transformers, and other equipment on wood, concrete, or steel poles across various weather conditions. Products carry Rural Utilities Service (RUS) approval and Buy America Qualified status, meeting regulatory requirements for safety and performance in electrical utility applications.

Frequently Asked Questions (FAQS)
Absolutely. RaxPower accepts minimum order quantities as low as 1 piece, allowing you to order small amounts for evaluation or small-scale projects without large commitments.
RaxPower offers a 2-year warranty on all products to ensure long-term performance, durability, and customer satisfaction.
Yes, RaxPower provides customized services including modifications to dimensions, materials, and mounting hardware. Customization is available for pole diameters ranging from approximately 90mm to 400mm, accommodating wood, concrete, and steel poles to meet your unique project needs.
Pole top brackets are constructed from durable materials such as ductile iron per ASTM A-536, hot-dip galvanized steel per ASTM A153 specifications, and aluminum alloy, providing enhanced corrosion resistance and long-term durability.
The brackets are engineered to withstand outdoor elements including storms, strong winds, and UV exposure, ensuring reliable performance in challenging environmental conditions.
These brackets are RUS approved and comply with ASTM A153 for galvanizing and ASTM A-536 for ductile iron. Type test reports and third-party certifications for IEC, ANSI, or other requirements are available upon request.
Voltage ratings vary by model, with common ratings including 35 KV, 69 KV, and up to 88 KV for certain configurations, ensuring compatibility with various electrical distribution requirements.
Mounting typically uses 5/8 or 3/4 through bolts or stud bolts. Some brackets are designed for two bolts vertically spaced, such as 16mm diameter bolts with 203mm center-to-center spacing, and may include slotted holes for slight variations.
Lead time depends on order volume and complexity. For prototypes or low-volume runs, RaxPower typically delivers within 5-7 working days, and rush orders can be accommodated to meet your project deadlines.
