As an aerial lineman, your duties revolve around the installation, maintenance, and repair of overhead or buried power lines or cabling used for electrical or power distribution systems. You climb poles or transmission towers to assess issues with the line or to connect a line to a construction site as it nears completion. You can find aerial lineman positions with power companies, utility providers, construction operations, or private contractors. You use a variety of specialized tools, such as cable splicers and climbing equipment.
