Condition Evaluation and Replacement Method of Damp Cable

Abstract

Cable lines are now being widely used. According to statistics data, cable dampness is the main factor affecting the operation of cable lines at present. If the cables are damp, evaluate the degree of damp and replace the cables that are severely damp in sequence. In this paper, the physical and chemical properties, mechanical properties and dielectric properties of the cable are used to evaluate the status of the cable. By comparing the length and carrying capacity of cables in operation, the degree of damp was sorted by skyline algorithm, and the most serious cables were replaced first.
