Electrical cross arms are horizontal structural members mounted on utility poles to support conductors, insulators, and electrical equipment in power transmission, distribution, and telecommunications systems. They maintain proper spacing between lines, prevent faults, and distribute mechanical loads to ensure system stability.
These components are constructed from galvanized steel, fiberglass, or wood, each selected for specific properties. Galvanized steel provides high strength and corrosion resistance through hot-dip galvanizing, fiberglass offers insulation and non-conductive characteristics with reduced weight, while wood delivers durability in certain environments. Standard dimensions range from 400mm to 6100mm in length, with section sizes from 40x40mm to 100x100mm and thicknesses between 3mm and 10mm. Load ratings span 2kN to 200kN, tailored to project requirements.
Cross arms are deployed in urban and rural power distribution networks, high-voltage transmission lines, telecommunications infrastructure, and street lighting systems. They organize and support overhead lines while elevating electrical components for enhanced safety. Installation involves positioning at the desired height, aligning pre-drilled holes, and securing with pigtail bolts, U-bolts, or double arming bolts, with cross arm braces providing additional stability.
Manufacturing employs precision techniques including press molding for burr-free hole creation and hot-dip galvanizing for corrosion protection. Products comply with American National Standards Institute (ANSI), International Electrotechnical Commission (IEC), and other industry standards, with third-party certifications available upon request.
Alley Arm
Side-mounted crossarm assembly that extends conductors away from the pole, used in alleys or tight corridors to maintain line clearance and proper alignment.
Angle Brace
One-piece V-type steel brace supporting heavy crossarm construction, installed under the arm to resist unbalanced loads and improve rigidity on transmission or distribution poles.
Cross Arm Brace
Flat or angle steel brace used in pairs beneath crossarms to align and support them, increasing strength and stability against vertical and transverse loads on utility poles.
Double Arming Plate
Thick steel plate used between two crossarms on the same pole to clamp and reinforce them together, providing robust support for insulators and hardware in double-armed construction.
Guard Arm Brace
Light-duty steel brace that supports a guard arm located below primary conductors, helping carry neutral or communication wires and maintain safe vertical spacing on multi-circuit poles.
Rectangular Cross Arm
Rectangular tubular steel crossarm mounted horizontally on poles or towers, providing high-strength support for insulators, conductors, and accessories with excellent corrosion-resistant performance.
