11M Tubular Pole 450daN 550daN ,Hot Dip Galvanization Steel Utility Pole,Low Silicon
Product Description
Transmission line poles and towers are tower structures used to support and raise overhead conductors, lightning rods and other accessories, so that conductors and conductors, poles and towers, conductors and lightning rods, and conductors on the ground or across objects to maintain a specified safe distance from the towering structure.According to the purposes are: tension tower, straight tower, corner tower, transposition tower (replacement of wire phase position tower), terminal tower and spanning tower.
To design in accordance with PLS software, we will require the following design parameters:
