The application provides a
submarine communication cable, relates to the cable field, and comprises a core and an inner protective layer, a shielding layer and an outer protective layer which are sequentially wrapped from inside to outside, further comprises an elastic layer and a gas delivery
assembly, the elastic layer is wrapped outside the outer protective layer, there is a gap between the outer protective layer and the elastic layer, and the gas delivery
assembly is located in the gap; the gas delivery
assembly comprises a gas delivery
pipe, solenoid valves and a
bus, the gas delivery
pipe is connected with the solenoid valves, and the solenoid valves are arranged at equal intervals along the axial direction of the gas delivery
pipe; a plurality of radial partitions are arranged in the gap, the radial partitions are arranged around the outer protective layer, the inner ring of the radial partitions is fixedly connected with the outer side surface of the outer protective layer, and the outer ring is fixedly connected with the inner side surface of the elastic layer; the radial partitions divide the gap into a plurality of annular cavities, the gas delivery pipe penetrates through the radial partitions, and the solenoid valves are located in the annular cavities, respectively; the
bus is fixed to the outer surface of the gas delivery pipe, and the solenoid valves are connected with the
bus, respectively.
