Our electric poles come in various cross-sectional forms including square, octagonal, I-shaped, circular, and other irregular sections. The most commonly used are circular and square cross-sections. We offer two types of circular electric poles: conical pole and equal diameter pole. The conical pole has a tip diameter of 100-230 millimeters with a taper of 1:75, while the equal diameter pole has a diameter of 300-550 millimeters. Both types have a wall thickness of 30-60 millimeters.
Our overhead power lines poles are available in heights of 30ft, 35ft, and 40ft, made of galvanized steel for durability in electric power transmission.
In China, our electric poles support various voltage levels including 220V, 380V, 6.3kV, 10kV, 35kV, 110kV, 220kV, 330kV, 500kV, and 1000kV. The power system consists of power plants, transmission lines, substations, distribution lines, and electrical equipment. Voltage lines above 35kV are considered transmission lines.
At CZEE, we pride ourselves on our team of professional engineering personnel trained in the latest software such as PLS-CADD, PLS-POLE, TOWER, and AutoCAD. With expertise in three different manufacturing processes, we specialize in producing steel towers, poles, and other steel structure supports for various applications.
