Description

A kind of PE waterproof layers water-proof cable

【Technical field】

It the utility model is related to a kind of cable, more particularly to a kind of PE waterproof layers water-proof cable.

【Background technology】

Power cable uses PVC sheath material more at present, outdoor in use, humidity resistance, ageing resistace are poor, influences to produce The using effect of product and life-span.According to waterproof power cable, can solve moistureproof and anti-aging problem, construction can also be saved Cost, save the material cost and manufacturing cost of cable in itself.In summary, for prior art the defects of, it is accordingly required in particular to anti- Water-based cable that can be good, to solve the deficiencies in the prior art.

【Utility model content】

The problem of to overcome existing cable poor waterproof properties, the utility model provide a kind of PE that can be solved the above problems Waterproof layer water-proof cable.

The technical scheme that the utility model solves technical problem is to provide a kind of PE waterproof layers water-proof cable, including conductor and PVC oversheaths, conductor outer cladding the first semiconductive waterstop, the first semiconductive waterstop outer cladding screen layer, screen layer outsourcing Insulating layer coating, insulating barrier outer cladding insulation screen, insulation screen outer cladding the second semiconductive waterstop, the second semiconductive stop Water band outer cladding copper strip shielding layer, copper strip shielding layer outer cladding band, band outer cladding PE water blocking layers, PE water blocking layer outer cladding steel Band armor, steel-tape armouring layer outer cladding PVC oversheaths, above layers are that concentric circles is set, the first semiconductive waterstop Thickness is equal with the thickness of the second semiconductive waterstop, steel-tape armouring layer surface set fold, the PE block water layer surface setting Arc-shaped convex, the shape size of the arc-shaped convex are equal.

Compared with prior art, a kind of PE waterproof layers water-proof cable provided by the utility model is protected by setting outside PVC Set and steel-tape armouring layer, it can effectively prevent PE waterproof layers water-proof cable from destroying appearance by hard thing, so as to play water-proof function, pass through First semiconductive waterstop, the second semiconductive waterstop and PE water blocking layers be set, three layers of waterproof layer, multi-angle without dead angle waterproof, Greatly improve water resistance.PE block water layer surface set arc-shaped convex, increase water repellent area, strengthen waterproof effect.Each circle The shape size of arc convex is equal, is easy to manufacture, and is advantageous to produce.

【Brief description of the drawings】

Fig. 1 is the utility model PE waterproof layer water-proof cable schematic diagrames；

Fig. 2 is the utility model PE waterproof layer water-proof cable PE water blocking layer structural representations；

In figure：Conductor 1, the first semiconductive waterstop 2, screen layer 3, insulating barrier 4, insulation screen 5, the second semiconductive stop Water band 6, copper strip shielding layer 7, band 8, PE water blocking layers 9, steel-tape armouring layer 10, PVC oversheaths 11.

【Embodiment】

In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only solving The utility model is released, is not used to limit the utility model.

As shown in figure 1, the utility model PE waterproof layers water-proof cable includes conductor 1, the first semiconductive of outer cladding of conductor 1 stops Water band 2, the outer cladding screen layer 3 of the first semiconductive waterstop 2, the outsourcing insulating layer coating 4 of screen layer 3, the outer cladding of insulating barrier 4 insulation screen Cover layer 5, the second semiconductive of the outer cladding waterstop 6 of insulation screen 5, the outer cladding copper strip shielding layer 7 of the second semiconductive waterstop 6, The outer cladding band 8 of copper strip shielding layer 7, the outer cladding PE water blocking layers 9 of band 8, the outer cladding steel-tape armouring layer 10 of PE water blocking layers 9, steel band The outer cladding PVC oversheaths 11 of armor 10, above layers are that concentric circles is set.Wherein, the thickness of the first semiconductive waterstop 2 It is equal with the thickness of the second semiconductive waterstop 6.The surface of steel-tape armouring layer 10 sets fold, is easy to bend.

Referring to Fig. 2, the surface of PE water blocking layers 9 sets arc-shaped convex 91, increase water repellent area, strengthen waterproof effect.Often The shape size of individual arc-shaped convex 91 is equal, is easy to manufacture, and is advantageous to produce.

Compared with prior art, a kind of PE waterproof layers water-proof cable provided by the utility model is protected by setting outside PVC Set 11 and steel-tape armouring layer 10, it can effectively prevent PE waterproof layers water-proof cable from destroying appearance by hard thing, so as to play water-proof function, By setting the first semiconductive waterstop 2, the second semiconductive waterstop 6 and PE water blocking layers 9, three layers of waterproof layer, multi-angle is without dead Angle waterproof, greatly improves water resistance.The surface of PE water blocking layers 9 sets arc-shaped convex 91, increases water repellent area, strengthens waterproof effect Fruit.The shape size of each arc-shaped convex 91 is equal, is easy to manufacture, is advantageous to produce.

Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model Any modification made within the principle of utility model, equivalent substitution and improvement etc. all should include the scope of protection of the utility model Within.
