LV cables use stranded copper or aluminum conductors. although small conductor of cables may use solid conductors. The overall assembly may be round or flat. Non-conducting filler strands may be added to the assembly to maintain its shape. Special purpose LV cables for overhead or vertical use may have additional elements such as steel structural supports. Some LV cables for outdoor overhead use may have no outer sheath.
