Description
Technical field
The present invention relates to electrical equipment, more particularly to a kind of high power cable of block-water performance.
Background technology
Electrical equipment includes primary equipment and secondary device, the secondary device that cable belongs in electrical equipment.With China
Economical continues to develop, and the application of cable is more and more wider, its performance requirement also more and more higher.Traditional construction of cable pine
Dissipate, unit area current-carrying capacity is small, in sleety weather, hydrone easily enters inside cable, so as to cause the generation of short circuit phenomenon, shadow
The stabilization of power transmission is rung, and jeopardizes the security of the lives and property of citizen.Above mentioned problem urgent need to resolve.
The content of the invention
The technical problem existed based on background technology, the present invention proposes a kind of high power cable of block-water performance, to solve
Certainly above-mentioned technical problem.
A kind of high power cable of block-water performance proposed by the present invention, including：Cable core, water blocking filler, armor and outer shield
Set；The cable core includes three mutual stranded cores, on arbitrary section, and the line of centres of three cores is in equilateral triangle,
Core includes wire, the insulating barrier that is extruded in outside wire positioned at middle part, wrapped screen layer outside insulating barrier, it is wrapped
Waterproof cushion outside screen layer, the inner sheath for being extruded in waterproof buffer exteriors, water blocking filler, which is filled out, to be set between core, armour
Dress layer is coated on water blocking filler periphery, and oversheath is coated on armor periphery.Conductor is twisted into circle, screen layer by multiple conducting wires
Formed by aluminium-plastic tape is wrapped, waterproof cushion is formed by waterstop is wrapped, and inner sheath is made up of vinyl polymer material,
Armor is made up of steel band, and oversheath is made up of high abrasion material water-proof material.
A kind of high power cable of block-water performance proposed by the present invention, cable core includes three mutual stranded cores, in office
Anticipate on section, the line of centres of three cores is in equilateral triangle, and this design makes the construction of cable compact, and unit area current-carrying capacity is big,
When by external stress, core is not susceptible to movement；Core includes the wire for being located at middle part, the insulation being extruded in outside wire
Layer, wrapped screen layer outside insulating barrier, wrapped waterproof cushion outside screen layer, is extruded in waterproof buffer exteriors
Inner sheath, water blocking filler, which is filled out, to be set between core, and armor is coated on water blocking filler periphery, and oversheath is coated on outside armor
In week, by above-mentioned design, oversheath can prevent hydrone from entering cable core, and water blocking filler can prevent hydrone from entering core,
Even if thering is inner sheath and waterproof cushion that small part hydrone enters in core, core through oversheath and water blocking filler also may be used
By hydrone isolation outside wire, the water resistance of cable is improved.A kind of high electric power of block-water performance proposed by the present invention
Cable, compact conformation, current-carrying capacity is big, can effectively prevent moisture penetration from entering inside cable and cause the generation of short circuit phenomenon.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the high power cable of block-water performance proposed by the present invention.
Embodiment
As shown in figure 1, Fig. 1 is a kind of structural representation of the high power cable of block-water performance proposed by the present invention.
Reference picture 1, a kind of high power cable of block-water performance proposed by the present invention, including：Cable core, water blocking filler 2, armouring
Layer 3 and oversheath 4；The cable core includes three mutual stranded cores 1, on arbitrary section, the line of centres of three cores 1
In equilateral triangle, core 1 includes the wire 11 for being located at middle part, the insulating barrier 12 being extruded in outside wire 11, wrapped in insulating barrier
Screen layer 13 outside 12, wrapped waterproof cushion 14 outside screen layer 13, be extruded in outside waterproof cushion 14 in
Sheath 15, specifically, conductor 11 are twisted into circle by multiple conducting wires, and waterproof cushion 14 is formed by waterstop is wrapped, blocks water and fill out
Material 2, which is filled out, to be set between core 1, and armor 3 is coated on the periphery of water blocking filler 2, and oversheath 4 is coated on the periphery of armor 3, oversheath
4 are made up of high abrasion material water-proof material.
Cable core in the present embodiment includes three mutual stranded cores 1, on arbitrary section, the center of three cores 1
Line is in equilateral triangle, and this design makes the construction of cable compact, and unit area current-carrying capacity is big, and when by external stress, core 1 is not
Easily it is moved.
Core 1 includes the wire 11 for being located at middle part, the insulating barrier 12 being extruded in outside wire 11, wrapped outside insulating barrier 12
The screen layer 13 in portion, wrapped waterproof cushion 14 outside screen layer 13, the inner sheath being extruded in outside waterproof cushion 14
15, water blocking filler 2, which is filled out, to be set between core, and armor 3 is coated on the periphery of water blocking filler 2, and oversheath 3 is coated on outside armor
In week, by above-mentioned design, oversheath 3 can prevent hydrone from entering cable core, and water blocking filler 2 can prevent hydrone from entering core
1, even if there have small part hydrone to pass through inner sheath 15 and waterproof in oversheath 3 and the entrance core 1 of water blocking filler 2, core 1 to be slow
Rushing layer 14 also can be by hydrone isolation outside wire 11, so as to improve the water resistance of cable.
Screen layer 13 in such scheme is formed by aluminium-plastic tape is wrapped, further improves the water resistance of cable.
Inner sheath 15 is made up of vinyl polymer material, between core 1 will not because of phase mutual friction and caused by wire 11 contact, it is ensured that
The stabilization of power transmission.
Armor 3 is made up of steel band, while playing shielding properties, further improves the water resistance of cable.
A kind of high power cable of block-water performance proposed by the present invention, compact conformation, current-carrying capacity is big, can effectively prevent water
Divide to penetrate into inside cable and cause the generation of short circuit phenomenon.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art the invention discloses technical scope in, technique according to the invention scheme and its
Inventive concept is subject to equivalent substitution or change, should all be included within the scope of the present invention.
