The electric poles come in various cross-sectional forms including square, octagonal, I-shaped, circular, or other irregular sections. The most commonly used are circular and square cross-sections. The poles are available in two types: 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.
The voltage levels commonly used in China range from 220V to 1000kV. The power system consists of power plants, transmission lines, substations, distribution lines, and electrical equipment. Voltage lines above 35kV are typically referred to as transmission lines.
