Abstract
The utility model discloses a seabed cross bonding electric force electric cable, comprising a core, an armoured inner covering, an armoured layer, and an armoured outer protection layer, which are arranged from the inside to the outside. The utility model is characterized in that the armoured layer is constituted by a plurality of non-magnetic metal wires which are evenly winded and arrayed, and a plastic antiseptic layer is arranged outside of the non-magnetic metal wires. The utility model has the advantages that the non-magnetic metal wire armoured structure substitutes the zinc coating steel wire armoured structure, which spares serious vortex and magnetic-lag depletion which are produced by adopting the zinc coating steel wire armoured structure, and the allowed current carrying capacity is about 30% than that of zinc coating steel wire armoured electric cables, and the tensile strength of the seabed cross bonding electric force electric cable is guaranteed, and a plastic antiseptic layer is arranged outside of the non-magnetic metal wires, thereby the non-magnetic metal wire armoured cable wires can be arranged in sea water for a long time and are not corroded.
Description
Technical field
The utility model relates to a kind of cable, especially relates to a kind of seabed cross-linked power cable.
Background technology
Have the single core of the 110kV level seabed crosslinked cable that in seawater, uses now and all adopt the zinc-coated wire sheathed structure basically, can produce very big eddy current loss and magnetic hysteresis loss but the cable of this structure lays when using in seawater, seriously reduce the ampacity of cable; Lay on land when using, excessive eddy current and magnetic hysteresis loss can make cable seriously generate heat, and destroy the insulation of cable, and cable is burnt out very soon.
Summary of the invention
Technical problem to be solved in the utility model provides and a kind ofly can reduce the higher seabed cross-linked power cable of eddy current and magnetic hysteresis loss and ampacity.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of seabed cross-linked power cable, comprise the core, armouring inner covering, armour and the armouring outer jacket that are provided with from inside to outside, described armour is made up of around the nonmagnetic metal silk of arranging many uniform ring, and described nonmagnetic metal silk is outside equipped with the plastics anticorrosive coat.
Described nonmagnetic metal silk can be aluminum-alloy wire, also can be stainless steel wire etc.
Described core comprises the copper conductor that is provided with from inside to outside, interior semi-conductive layer, crosslinked polyetylene insulated layer, outer semiconducting layer and screen.
Described screen comprises semiconductive waterstop, metallic sheath and the metallic sheath outer jacket that is provided with from inside to outside.
Compared with prior art, the utility model has the advantages that substituting the zinc-coated wire sheathed structure with nonmagnetic metal silk sheathed structure had both exempted serious eddy current, the magnetic hysteresis loss of taking the zinc-coated wire sheathed structure and producing, it is nearly 30% to make it allow ampacity to exceed than the permission ampacity of zinc-coated wire armoured cable, has guaranteed the tensile strength of seabed cross-linked power cable again; And be outside equipped with the plastics anticorrosive coat at the nonmagnetic metal silk, make nonmagnetic metal silk armoured cable place seawater for a long time and can not be corroded; Lay on land when using, also exempted eddy current and magnetic hysteresis loss, its security performance is guaranteed to the damage that cable brings.

Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the enlarged diagram of aluminum-alloy wire of the present utility model.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in the figure, a kind of seabed cross-linked power cable, comprise the copper conductor 1, interior semi-conductive layer 2, crosslinked polyetylene insulated layer 3, outer semiconducting layer 4, semiconductive waterstop 5, metallic sheath 6, metallic sheath outer jacket 7, armouring inner covering 8, armour 9 and the armouring outer jacket 10 that are provided with from inside to outside, armour 9 is made up of around the aluminum-alloy wire of arranging 11 many uniform ring, the every aluminum-alloy wire 11 outer plastics anticorrosive coats 12 that are arranged with.
In the foregoing description, armour 9 used aluminum-alloy wires 11 also can be substituted by nonmagnetic metal silks such as stainless steel wires.
