The Double Arming Plate supports and secures two crossarms on a single utility pole in power distribution systems, particularly in double-arm construction common in Russia and similar regions. This reinforcing plate enhances structural integrity and load-bearing capacity by providing dual arm support that minimizes crossarm movement and shifting during installation and operation.
Constructed from carbon steel or high-strength steel (with aluminum options available), the plate undergoes hot-dip galvanizing per ASTM A-153 standards for corrosion resistance and extended service life. The design includes pre-drilled mounting slots (typically 11/16″ x 3-1/2″ or 13/16″ x 3-1/2″) and center holes for insulator pins or deadend connections. Standard dimensions range from 4 inches in width and 17 to 24 inches in length, with approximately 0.5-inch thickness.
The heavy-duty construction distributes loads evenly across the pole assembly, reducing structural failure risk while the galvanized coating protects against environmental degradation. The plate installs easily with standard tools, reducing labor time, and can be customized to accommodate specific pole and crossarm sizes with tolerances ensuring field compatibility.
The product meets ISO 9001 quality management standards and carries Rural Utilities Service (RUS) listing for utility applications, ensuring compliance with industry requirements for electrical infrastructure reliability and safety.

Frequently Asked Questions (FAQS)
What is a Double Arming Plate and what is its primary function?
RaxPower's Double Arming Plate is a crucial component in power distribution systems that supports and secures two crossarms on the same pole. It serves as a connecting element between the crossarms and the pole, enhancing structural integrity and load-bearing capacity while providing a mounting position for insulator pins or deadend connections.
What materials and corrosion protection are used in Double Arming Plates?
Double Arming Plates are constructed from robust materials such as steel, carbon steel, or malleable iron for durability and long-term performance. They are hot-dip galvanized per ASTM A-153 and ISO 1461 standards, providing superior corrosion resistance that ensures longevity and reliability even in harsh environmental conditions while reducing maintenance needs.
What are the standard dimensions and mounting specifications?
Standard dimensions include widths like 4 inches and lengths such as 17 inches or 24 inches, with variations available. They feature precision-punched mounting holes, including slots (e.g., 11/16 x 3-1/2) and connection holes (e.g., 13/16), designed to fit poles with top diameters from 8-12 inches and gains 0.5 inch deep for secure installation.
How are Double Arming Plates installed on utility poles?
Installation is straightforward and designed for use with standard tools to reduce labor time. The plates are secured to the pole and crossarms through pre-drilled holes and slots, ensuring a stable platform for attaching insulator pins and facilitating efficient assembly in double-arm construction.
