This paper presents a cartographic design for 3D representation of electric power networks. So far, there are few research works related to 3D cartographic design, mainly considering the suitability of symbology to map use. Most 3D maps are produced considering the same aspects used to design 2D maps and this can lead to problems in the final product and, consequently, in the way maps are used. Hence, using as reference the cartographic design for 2D and 3D maps proposed by Sluter (2008) and Haeberling (2008), respectively, the existent differences between them were analyzed. As a result of this analysis it was noticed that the main change is related to symbology desing. Afterward, this paper presents two different proposals of symbology: one realistic and other geometric. These two symbologies were applied to the study area and the results point out to better differentiation of network elements when geometric symbols were used.
