The structure of 110kV high-voltage cable terminal is compact and the distribution of electric field is complex. The magnitude and distribution characteristics of electric field on body surface of live line workers are an important basis for formulating the safety protection and operation methods. In aim to attain the distribution of electric field on body surface of live-line workers under different working conditions, Combined with typical 110kV cable outdoor terminal, established human body’s surface electric field analysis model under three working conditions, namely earth potential, flaoting potential and equal potential, and horizontal and vertical entry path. Analysis results show that: The distortion field intensity of head, hands and feet is relatively large. With the distance between workers and cable terminal increasing by 0.1m, voltage decreases by 8% and electric field drops exponentially. When workers accesses to equal-potential in vertical direction, electric field rises about 2.2kV/m for each upward movement of 0.1m. When human body is in different phases, electric field in phase A to phase C gradually increases by 11% per phase. The operation mode and access path provide a reference for cable terminal live working, which has theoretical value and practical significance for ensuring safety of live line maintenance.
