Description
Technical field
This utility model relates to a kind of sea electric power cable, particularly relates to the single subsea power electricity of a kind of segmentation armouring
Cable.
Background technology
At present, existing sea electric power cable (hereinafter referred to as sea cable) structure typically all utilizes zinc-plated round copper wire as sea
Cable armoured, thus ensure tensile strength and the corrosion resistance of sea cable.But sea cable can be at protective metal shell and armoured in running
On can produce induction electromotive force, need the method using two sides earth to eliminate, be allowed to safe operation, but can produce again a large amount of
Circulation loss, cause sea cable especially its land part current-carrying capacity be substantially reduced.The extra large cable current-carrying capacity of same structure is land
Part is very big with the current-carrying capacity difference of underwater portion, and the current-carrying capacity of the sea land part of cable and underwater portion can not well mate,
Cause the wasting of resources to a certain extent.
Utility model content
The technical assignment of the technical problems to be solved in the utility model and proposition be prior art is carried out improve with
Improve, it is provided that the single sea electric power cable of a kind of segmentation armouring, to reduce the purpose of cost.To this end, this utility model
Take techniques below scheme.
A kind of single sea electric power cable of segmentation armouring, including in the core of outer setting, screen layer, insulating barrier, absolutely
Edge body screen layer, lead set, inner protective layer, armor and external protection, described armor is formed by many one metal wires are stranded, its
It is characterised by: armor is divided into for the first land armor with for the second armor under water, the one of the first armor
End docks shape all-in-one-piece armor with one end of the second armor.First armor and the series connection of the second armor, sea cable is at water
Lower part and land part are by different armor structures, and the extra large cable of the technical program both can improve the overall mechanicalness of sea cable
Can, it is also possible to improve the current-carrying capacity of sea cable, reduce whole piece sea cable cost.
As improving further and supplementing technique scheme, this utility model also includes that following supplementary technology is special
Levy.
The first described armor is blue or green round copper wire armor；The second described armor is zinc-coated wire armor, the
The blue or green round copper wire of one armor and the zinc-coated wire welding of the second armor.Land part use blue or green round copper wire as armor with
The current-carrying capacity of sea cable is greatly improved；And underwater portion uses zinc-coated wire, to ensure and the sea cable equal current-carrying capacity of land part
On the premise of, reducing the manufacturing cost of sea cable, underwater portion uses zinc-coated wire to also ensure that the severe ring of opposing of sea cable simultaneously
The performance in border.
Inner protective layer is semiconductive polyethylene layer.
Described core is the conductor stranded by copper conductor.
It is provided with armouring inner cushion layer between described inner protective layer, armor.Be conducive to improving intensity and resistance to tension.
Described armouring inner cushion layer is the Colophonium inner liner using polypropylene rope as internal stiffeners.It is effectively improved tension energy
Power.
Described external protection is the outer jacket with polyurethane as material.
Beneficial effect:
The technical program both can improve the overall mechanical properties of sea cable, it is also possible to improves the current-carrying capacity of sea cable, reduces whole piece
Sea cable cost.
Sea cable part and land part under water are by different armor structures, and land part can use blue or green round copper wire conduct
Armor is to be greatly improved the current-carrying capacity of sea cable；And underwater portion can use zinc-coated wire, same with the sea land part of cable in guarantee
On the premise of current-carrying capacity, reducing the manufacturing cost of sea cable, underwater portion uses zinc-coated wire to also ensure that supporting of sea cable simultaneously
The performance of anti-adverse environment.
Accompanying drawing explanation
Fig. 1 is this utility model horizontal sectional structure schematic diagram.
Fig. 2 is this utility model longitudinal direction sectional structure schematic diagram.
Detailed description of the invention
Below in conjunction with Figure of description, the technical solution of the utility model is described in further detail.
Fig. 1, shown in 2, this utility model include in the core 1 of outer setting, screen layer 2, insulating barrier 3, insulator shielding
Layer 4, lead set 5, inner protective layer 6, armor 7 and external protection 8, described armor is formed by many one metal wires are stranded, and it is special
Levy and be: armor is divided into for the first land armor 71 with for the second armor 72 under water, the first armor 71
One end dock shape all-in-one-piece armor with one end of the second armor 72.The armor of the technical program according under water, land
On different requirement carry out subsection setup, both can improve the overall mechanical properties of sea cable, it is also possible to improve the current-carrying capacity of sea cable, fall
Low whole piece sea cable cost.
In the present embodiment, the first described armor 71 is blue or green round copper wire armor；The second described armor 72 is
Zinc-coated wire armor, the blue or green round copper wire of the first armor 71 and the zinc-coated wire welding of the second armor 72.Can certainly
Substitute with other material.
