Galvanized crossarms for cable trays are typically made of Q235 low-carbon steel via rolling. 5mm, 3mm, and 4mm) based on load levels. Our focus has always been on solutions from the field of cable support systems. They serve as support structures for insulators, conductors, and other electrical equipment, ensuring proper spacing and stability. The National Electrical Safety Code (NESC) establishes the criteria to be followed in the design, construction, and operation of the electric distribution system. The requirements for. Single-pole single crossarm is mainly composed of crossarm, U-shaped clamp, M-type pad (some poles also have support feet and support foot clamp); single-pole double crossarm is mainly composed of crossarm, stud bolt, M-type pad.
