Comparison and Selection of Three-Core Cable and Single-Core Cable

Chunyang Liu

Abstract

Abstract The selection of three-core and single-core power cables generally follows the following rules: three-core cables are selected under the condition of 6-10 kV voltage, and single-core cables are selected when the voltage level is 66 kV or above. However, 35 kV voltage grade cable has both three cores and single core. How to choose the right one is a difficult problem for engineers and technicians. Through the analysis and comparison of 35 kV three-core cable and single-core cable, the applicable environment and conditions of each cable are defined, which can provide reference and help for the majority of electric power technicians in choosing cable in engineering practice.
