Embodiment Construction

[0040] Refer to attached Figure 1~4 ,exist figure 1 Among them, the bundled frequency conversion submarine cable includes a frequency conversion cable unit 1, a gap filling material 2, an armored cushion layer 3, a metal armor layer 4, and a submarine cable outer sheath 5.

[0041] Frequency conversion cable unit 1 is a relatively independent frequency conversion cable, see the detailed structure figure 2 To describe, there are 2 to 10 frequency conversion cable units 1 . A plurality of frequency conversion cable units 1 are twisted into a cable, and gap filling materials 2 are filled between the several frequency conversion cable units 1, and the gap filling material 2 is a rope-like filler with seawater corrosion resistance and good flexibility. There is an armored cushion layer 3 on the outside of several frequency conversion cable units 1 twisted into cables, and the armored cushion layer 3 is an extruded plastic cushion layer or a seawater-resistant reinforced fiber b...

Abstract

The invention relates to a bunched frequency conversion submarine cable and a manufacturing method thereof, which legitimately combines a plurality of frequency conversion cable units together and transmits power supplies of different parameters to electric submersible pumps of multiple producing wells on a marine petroleum exploitation platform. The submarine cable comprises frequency conversioncable units, gap filling materials, an armoring cushion layer, a metal armoring layer and a submarine cable outer protective layer, wherein the frequency conversion cable units are twisted into the cable, the gap filling materials are filled among the frequency conversion cable units, the armoring cushion layer is arranged outside the frequency conversion cable units twisted into the cable, the metal armoring layer is arranged outside the armoring cushion layer, and the submarine cable outer protective layer is sheathed outside the metal armoring layer; and each frequency conversion cable unit comprises a power cable core, a control cable core, a gap filler, a metal shield layer and a protective layer, wherein the power cable core comprises a power cable core conductor, a power cable coreinsulation layer, a semiconductive shield layer and a power cable core metal shield layer, and the control cable core comprises a control cable core conductor, a control cable core insulation layer and a control cable core metal shield layer.

Description

technical field [0001] The present invention relates to a bundled frequency conversion submarine cable and a manufacturing method thereof. It is composed of a plurality of frequency conversion cable units rationally combined, and a metal protective layer is added to the outside of the cable. Submersible pumps deliver power with different parameters. Background technique [0002] With the strengthening of my country's offshore oil exploitation and the continuous improvement of oil extraction technology, offshore oil exploitation has achieved rapid development. There are often multiple electric submersible pumps working at the same time on an offshore oil platform, and because the manufacturers and operating parameters of each electric submersible pump are different, the power parameters from the electric submersible pump transformer are also different, and the power parameters transmitted by the same cable are Certainly, this requires multiple cables to feed ESPs of differen...
