Problems solved by technology

[0002] At present, AC cables are widely used in land cables and submarine cables, but AC cables generally have the following problems: large line loss during power transmission; when the transmission capacity is large, the diameter and weight of the AC cable are large, and the cost is high; Due to the limitation of distance, long-distance large-capacity power transmission cannot be realized; the construction investment required for AC cables is relatively high
The photoelectric composite filling layer of this submarine cable is arranged between the inner lining layer and the armor layer. When the submarine cable is damaged by external force, the armor layer of the submarine cable bears the brunt, and the photoelectric composite filling layer directly protected by it will be destroyed immediately. , the optical cable is also extremely vulnerable, which affects the transmission of communication

Abstract

The invention discloses a photoelectric composite direct current submarine cable for + / - 160kV flexible power transmission. The photoelectric composite direct current submarine cable comprises a water blocking conductor, a conductor shielding layer, an insulating layer, an insulating shielding layer, a semiconductive resistance water hose, an alloy lead sleeve, a PE sheath, an inside liner, an armor layer and an outside layer which are sequentially arranged from inside to outside, wherein the water blocking conductor is located in the center of the cable, the outside layer is located on the outermost layer of the cable, the submarine cable further comprises a photoelectric composite layer, and the photoelectric composite layer is located between the semiconductive resistance water hose and the allay lead sleeve. According to the submarine cable, long-distance high-capacity transmission of electric power and communication signals can be achieved, and damage risks of the cable are reduced.

Description

technical field [0001] The invention relates to a submarine cable, in particular to a photoelectric composite DC submarine cable for ±160kV flexible power transmission. Background technique [0002] At present, AC cables are widely used in land cables and submarine cables, but AC cables generally have the following problems: large line loss during power transmission; when the transmission capacity is large, the diameter and weight of the AC cable are large, and the cost is high; Due to the limitation of distance, long-distance large-capacity power transmission cannot be realized; the construction investment required for AC cables is relatively high. [0003] Compared with AC transmission, DC transmission has the advantages of high transmission power, small line loss, convenient adjustment of current and change of power transmission direction, low investment cost, reduction of short-circuit current between the main line and the grid, and small corona radio interference.
