DC power cable

The utility model relates to a power cable, especially to a DC power cable. The DC power cable is provided with a conductor (1), an insulating layer (4), a metal shielding layer (7), a wrapping layer (8) and an outer sheath (9) together arranged from inside to outside successively. The DC power cable is also provided with a semi-conductive wrapping shielding layer A (2), a semi-conductive shielding layer A (3), a semi-conductive shielding layer B (5) and a semi-conductive wrapping shielding layer B (6). The semi-conductive wrapping shielding layer A (2) wraps the conductor (1). The semi-conductive shielding layer A (3) wraps the semi-conductive wrapping shielding layer A (2) in an extruding manner. The insulating layer (4) wraps the semi-conductive shielding layer A (3) in an extruding manner. The semi-conductive shielding layer B (5) wraps the insulating layer (4) in an extruding manner. The semi-conductive wrapping shielding layer B (6) wraps the semi-conductive shielding layer B (5). The metal shielding layer (7) wraps the semi-conductive wrapping shielding layer B (6). The DC power cable in the utility model has characteristics of excellent flexibility, excellent electromagnetic shielding capacity, safe and reliable performance and long service lifetime. The DC power cable in the utility model is environment friendly.
