Example Embodiment

[0018] Example 1

[0019] A cross-linked polyethylene insulated optical fiber composite submarine power cable includes a cable core, an optical unit 10, a reinforced filling strip 8, a wrapping tape 9, an inner lining layer 11, an armor layer 12 and an outer coating layer 13.

[0020] There are three cable cores distributed in a star shape, and the wrapping tape 9 is wrapped around the outer circumference of the cable cores. The reinforced filling strip 8 is filled in the cable core gap inside the tape 9 , and a reserved hole 14 is arranged on it, and the optical unit 10 is placed in the reserved hole 14 . The reinforced filling strip 8 is made of PP material, which is hard and not easy to deform. It is filled in the cable gap of the product, on the one hand, it can ensure that the cabled product is dense and round; on the other hand, it can protect and fix the optical unit. function, and ensure that the optical unit is not damaged during the laying process. In addition, the...

Abstract

The invention discloses a cross-linked-polyethylene insulating optical-fiber composite submarine power cable. The cable comprises a cable core, an optical unit, a reinforced filling strip, a wrapping tape, an inside liner, an armor layer and an outer covering layer, wherein the wrapping tape, the inside liner, the armor layer and the outer covering layer successively wrap outer sides of the cable core, the optical unit and the reinforced filling strip. The reinforced filling strip is filled in a cable core gap of an inner side of the wrapping tape and is provided with a preformed hole. The optical unit is placed in the preformed hole. By using the cross-linked-polyethylene insulating optical-fiber composite submarine power cable of the invention, the structure is simple; the design is reasonable; the reinforced filling strip is filled in the cable core gap and the optical unit is placed in the preformed hole of the reinforced filling strip so that on one hand, effects of protecting and fixing the optical unit are achieved, the optical unit can be prevented from being damaged during a laying process and a processing risk is reduced; and on the other hand, a degree of density and a spherical degree of a cabling product are increased.

Description

technical field [0001] The invention relates to the field of power cables, in particular to a cross-linked polyethylene insulated optical fiber composite three-core submarine power cable, which can be used as a 10-500kV three-core submarine power cable. Background technique [0002] At present, the common optical fiber composite three-core submarine power cable, such as the submarine power cable disclosed by CN 202394580 U, has a cable core composed of a water-blocking conductor and an inner shielding layer, an insulating layer, and an outer shielding layer arranged outside the water-blocking conductor in sequence. It is composed of a water-blocking buffer layer, an optical cable unit is arranged in the gap of the cable core, and the space around the optical cable unit is filled with fillers, and the filler and the power cable are successively provided with wrapping tape, inner cushion layer, armor layer and Outer layer. [0003] The processing technology of the existing op...
