The Rectangular Cross Arm supports conductors in power transmission and distribution systems, maintaining proper spacing and stability to prevent short-circuiting. Made from rectangular steel tubing—typically Q235 steel—with a hot-dip galvanized finish, it provides high strength, durability, and corrosion resistance for overhead lines and utility poles.
Standard sizes include 8FT, 10FT, and 12FT lengths with common dimensions of 80mm x 100mm. The cross arm can be customized in length, thickness, and other dimensions to meet specific load specifications and installation requirements.
Applications range from single-phase to three-phase circuits in power distribution networks operating at voltages from 13.8 kilovolt (kV) to 69 kV. It supports insulators, transformers, and other pole line hardware in overhead power line installations.
Installation involves horizontal mounting on utility poles or towers using pre-drilled holes for bolts or lag screws. The galvanized finish minimizes maintenance needs while ensuring long-term functionality in harsh environmental conditions with moisture exposure.
Rectangular Cross Arm Wholesaler with Proven Industry Standards
