Abstract
The utility model discloses a double water-resistance cable, which comprises cable cores. Each cable core is formed by twisting a plurality of wire cores. Each cable core consists of a conductor in the middle, and a shielding layer an insulating layer which are sequentially arranged on the outside of the conductor. Filling materials are filled in gaps between the cable cores. An inner sheath, an armor layer and an outer sheath are sequentially arranged outside each cable core. A metal waterproof sheath is arranged on the outside of the insulating layer of each wire core. A metal composite layer is coated outside each cable core in a sealing mode. A single layer waterproof structure of a normal water-resistant cable is replaced by the double water-resistance structure. Particularly, the metal waterproof sheath is added outside each insulating wire core of the power cable, and the metal composite layer is further added on each cable core after the cable is finished, so that a double water-resistance structure is formed and technological defects of the prior art are overcome. Additionally, the metal waterproof sheath of the double water-resistance cable can replace the metal shielding layer, and meanwhile, the insulating wire core is protected.
Description
Technical field
The utility model belongs to the power cable technical field, specifically is to block water a kind of improvement of the construction of cable of routine.
Background technology
As everyone knows; the conventional cable that blocks water is in necessity protection of moisture content during to cable intrusion; people apply various material water-proof materials usually outside core or cable core; form the cable that blocks water; but the water blocking layer of these cables all seriously hinders the heat radiation of cable self; influence the safe operation of cable to a great extent; and the disclosed employing aluminium of Chinese patent ZL200720045736.6 cover is as the cable that blocks water of water blocking layer; the problems referred to above have been solved; but the structure of its phase-splitting aluminium cover can't stop moisture content to enter cable core inside; moisture content is as easy as rolling off a log in the cable production process and in the transportation installation process enters; cause corrosion to the aluminium cover; lost water stop function at last; and function of shielding and electrical property brought very bad influence; prior art can't satisfy requirement special to the cable water stop function in the big environment of moisture, so invent a kind of dual water stop function that has, has not only protected cable core but also has protected the reinforcement of core the block water needs in cable fulfils market and the development of industry.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and the better dual cable that blocks water of a kind of block-water effect is provided.
The dual cable that blocks water described in the utility model comprises the cable core that is twisted into by the several wire core, and described core is by the conductor of centre, and the screen and the insulating barrier that are successively set on outside the conductor are formed; Space between the cable core is filled with filler, and cable core sets gradually inner sheath, armour and oversheath outward, and the metal waterproof jacket is set outside the insulating barrier of core, at cable core external seal clad metal composite bed.
When being used for medium and high voltage cable, between insulating barrier and metal waterproof jacket, set up insulation screen.
Above-mentioned metal waterproof jacket is light cover or radiation fins, adopts radiation fins can increase the bending property of cable.And metal composite layer can adopt plastic-aluminum combined layer or steel to mould composite bed, and this mainly uses the desirable strength decision according to cable.
The utility model becomes dual stop water with the cable that blocks water of routine by the single ply waterproofing structure.Specifically, outside the power cable insulation core, apply the metal waterproof jacket exactly, outside cable core, apply metal composite layer behind the stranding once more, constitute dually block water, water-retaining structure, thereby overcome the deficiencies in the prior art.In addition, all right alternative metals screen of metal waterproof jacket of the present utility model has been accomplished the protection to insulated wire cores simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the dual cable that blocks water of the present utility model, primary structure comprises conductor 1, screen 2, insulating barrier 3, insulation screen 4, metal waterproof jacket 5, filler 6, metal composite layer 7, inner sheath 8, armour 9 and oversheath 10.
Its agent structure is the cable core that is twisted into by the several wire core, and wherein core is the conductor 1 by the centre, and is successively set on the outer screen 2 of conductor, insulating barrier 3, insulation screen 4, metal waterproof jacket 5 compositions.Space between the cable core is filled with filler 6, and cable core sets gradually metal composite layer 7, inner sheath 8, armour 9 and oversheath 10 outward.。
Metal waterproof jacket 5 can be aluminium cover, aluminum alloy sleeve, also can be plumbous cover, lead alloy cover.Can be the light cover, also can be radiation fins, to increase the bending property of cable.Metal composite layer can adopt aluminium-plastic tape, also can adopt composite steel-plastic belt, mainly uses the desirable strength decision according to cable.
The block water manufacture method of cable of the utility model, be that the metal waterproof jacket on the leader cable core 5 is replaced wrapped metal screen layer, stranding on request then, at cable core external seal clad metal composite bed 7, matching with metal waterproof jacket 5 reaches dual stop water and function.Extrude sheath again, require routinely to carry out armouring, extrude outer jacket.
