Title:
DC SUBMARINE CABLE
Document Type and Number:
WIPO Patent Application WO/2021/093085
Kind Code:
A1
Abstract:
The present invention provides a DC submarine cable, which comprises a conductor unit, an insulation unit and a protection unit which are sequentially arranged from inside to outside, wherein the protection unit comprises a water blocking tape, a metal protective layer and an outer sheath which are sequentially arranged from inside to outside, wherein a return unit is further arranged in the DC submarine cable, and the return unit has the same current carrying capacity as that of the conductor unit. When a certain DC submarine cable in the same DC transmission circuit fails, a return conductor layer in another intact DC submarine cable can be used as a return path to form a loop with its own conductor to continue working, ensuring that a complete dynamic DC submarine cable has 50% of the power transmission capacity of the original transmission circuit.
