Abstract::Taking 10 kV straight dual concrete pole in mountainous area as the background,the electrical design and verification for ironwork of straight dual concrete pole are carried out. MathCAD software is used to write the calculation programs. Considering different meteorological district,different altitude area,different cross - section conductor,different suspension insulator string and other conditions,the Kv value is adjusted,the swing angle of insulator string of straight dual concrete pole is calculated,the diagram of gap circle is drawn,and the size of cross arm and the electrical location of diagonal bracing are determined for 10 kV straight dual concrete pole,which provides the necessary electrical conditions for the structure design of cross arm and diagonal bracing.
