Weakness, protect the environment in lake.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the pollution-free lake cable of novel environment friendly.
The components in the drawings are labeled as follows: 1, filled layer；2, fiber unit；3, conductor；4, conductor shield；5, water resistant
Set insulating layer；6, insulation screen；7, metal screen layer；8, radial resistivity water layer；9, nonmetallic oversheath；10, twining package tape；11,

Specific embodiment
The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, to make the protection scope of the utility model apparent clear
Define.
The utility model embodiment includes: a kind of pollution-free lake cable of novel environment friendly, comprising: several conductor structures and outer inclusion
Structure composition, the externally-packed structure is wrapped in several conductor structure outer walls, between the externally-packed structure and the conductor structure
Equipped with filled layer 1.
In the present embodiment, the quantity of the conductor structure is three.
Several fiber units 2 are installed, in the present embodiment, the quantity of the fiber unit 2 is two in the filled layer 1
It is a.
The conductor structure is by conductor 3, conductor shield 4, water resistant tree insulating layer 5, insulation screen 6, metal screen layer
7, radial resistivity water layer 8 and nonmetallic oversheath 9 form, the conductor shield 4, the water resistant tree insulating layer 5, insulation screen
It covers layer 6, the metal screen layer 7, the radial resistivity water layer 8 and the nonmetallic oversheath 9 and is successively wrapped in the conductor 3
On, the conductor 3 is water-blocking conductor, 3 every layer of longitudinal wrap semiconductor waterstop of conductor, so that the block-water performance of the conductor 3
More preferably.
The water resistant tree insulating layer 5 substantially increases the water tree resistant property of insulating materials.
The externally-packed structure is made of twining package tape 10, liner layer 11, wire armouring 12 and serving 13, the twining package tape
10, the liner layer 11, the wire armouring 12 and the serving 13 are successively wrapped in several conductor structure outer walls,
Since metal is heavy metal in traditional lead alloy sheath structure, lake is generally used as drinking water source more, and metal is weight
Metal is harmful to the human body, and can generally coat pitch outside traditional lead alloy sheath, and pitch pollutes the environment, so this hair
It is bright middle using the wire armouring 12, it can satisfy the short circuit current requirement of system, and will not pollute to lake.
The wire armouring 12 needs to select Sheathed metal silk diameter according to construction, to meet the drawing of practice of construction armouring
Force request.
The serving 13 is that the plastics of waterproof wear-resistant material extrude, and keeps it more durable environment friendly and pollution-free.
Compared with prior art, the pollution-free lake cable of a kind of novel environment friendly of the utility model, the lake cable not only meet current-carrying
The requirement of amount, solves the restricted problem of sea cable inland transport inconvenience, and overcomes the weakness of insulation water tree resistant property difference, saves
The use for having removed pitch, protects environment, produces, transports compared with traditional sea cable, construction is easier, same size section lake
Cable outer diameter is smaller, and quality is lighter, more saving cable material, solves the problems, such as the small lake of the depth of water and land electricity power growth requirement.
In the description of the present invention, it should be noted that term " on ", "lower", "left", "right", "inner", "outside" etc.
