Power pole and its components mainly support and shift power cable and its direction to properly distribute electric power to the need. Power pole assembly includes such components as supporting pole, crossarms, bands for crossarms and insulators. Considerable portion of external force are to be applied to crossarms and bands which connect crossarms to the poles. One-directional bands, 1D bands, are used for single crossarms and two-directional bands, 2D bands, for double cross arms. In the case of replacing a single crossarm by double crossarms, a band also has to be changed to a 2D band. Since replacing bands require a lot of work, a suggestion which utilize adapters to install double bands without the replacement of bands is made. This paper compares the results of stress and fatigue analysis of double crossarms with 1D band and adapter and double crossarms with 2D bands by finite element analysis. Finally structural integrity of the two structures are evaluated and then compared.
