A utility lineman is a broad term for professionals who build, maintain, and repair electrical power systems. An overhead lineman works on power lines and equipment suspended on poles or towers. Their tasks involve stringing conductors, installing transformers, and using specialized climbing gear and bucket trucks. An underground lineman focuses on the buried cables and equipment, which requires trenching and working in manholes and vaults. They use specialized underground cable laying equipment and tools for splicing and terminating cables.
