ABSTRACT

The cables were mostly laid overhead for a score of years, but the exposed metal wires in cities were easy to be corroded by acid-base gas and water vapor in the atmosphere, which had many hidden dangers. Therefore, more and more places choose to lay cables underground. The underground cable can improve the reliability of the urban power grid and the transmission capacity of urban lines, beautify the urban environment, and improve urban the utilization value of urban land. However, the repair of underground cables is more difficult, need good non-human material and financial resources. Based on the tracking ability, platform stability and maneuverability, this paper is committed to selecting appropriate robots and sensors to locate underground cable faults and reduce the workload of cable maintenance.
