Photoelectric composite submarine cable with rated voltage 220kv

Abstract

The invention discloses a photoelectric composite submarine cable with rated voltage 220kv. The cable comprises a conductor, an insulating shielding layer and an outer sheath, wherein a conductor shielding layer is extruded outside the conductor; the insulating shielding layer is arranged outside the conductor shielding layer; an XLPE (Cross Linked Polyethylene) insulating layer is arranged between the conductor shielding layer and the insulating shielding layer; the insulating shielding layer is formed by tightly extruding a semiconductor resistance water tape, a lead alloy sheath and a bituminous anti-corrosive layer from the inside out; the outer sheath is arranged outside the cable, and extruded on the surface of an inner sheath; a composite layer is arranged between the bituminous anti-corrosive layer and the inner sheath; and a plurality of tightly arrayed steel tape armor strips are arranged in the composite layer. The cable has good shielding property, bending resistance, energy saving and environmental protection and excellent interference resistance.

Description

technical field [0001] The invention relates to the field of cables, in particular to a photoelectric composite submarine cable with a rated voltage of 220kv. Background technique [0002] At present, with the development of human society and the improvement of living standards, the resources on the earth are becoming more and more tense. Inefficient mining, man-made destruction and waste have depleted the limited land resources such as oil, natural gas and coal. Therefore, many countries have set their energy development goals to the ocean, and marine resources will become the main source of energy for human beings in the near future, so submarine cables are becoming more and more important, so this requires cables to have good electrical conductivity, energy saving and environmental protection, and excellent performance Due to the characteristics of water resistance and corrosion resistance, the existing submarine cables cannot be well adapted to the submarine environment...
