Abstract
The utility model discloses a cross-linked polyethylene cable, which comprises a plurality of strands of cables. Each cable comprises conductor cores and an insulating layer wrapped outside the conductor cores. Each insulating layer has a two-layer structure comprising an inner insulating layer and an outer insulating layer sequentially from inside to outside. A waterproof layer and an armored layer are wrapped on the outer wall of each cable sequentially from inside to outside. The cross-linked polyethylene cable has a simple structure, high water resistance and a wide application range; a machining process is simple; and the two insulating layers are arranged, so that the aim of flame retardance is fulfilled, and influence on the electrical performance and thermal stability of a product is avoided.
Description
Technical field
The utility model relates to a kind of cable, relates in particular to a kind of twisted polyethylene cable.
Background technology
In the prior art, cable has wire stylet, insulator, fill material or the like to constitute, and the outer surface of conductor only is provided with the non-flame retardant insulation of one deck.In order to improve the lsafety level of electric wiring; The fire-retardant problem of electric wire more and more causes people's attention; Fire-retardantization of cable become a comprehensive developing direction of line cable industry, and cross-linked polyethylene insulated cable is because temperature resistant grade is high, and advantages such as avirulence gas release more and more are widely used; But the cross-linking polyethylene materials oxygen index is lower; Very easily burning, this has brought the certain designed difficulty for the flame-proof crosslinked polyethylene insulated cable, also has existing twisted polyethylene cable water proofing property relatively poor.
Summary of the invention
To the problem that above-mentioned prior art exists, the utility model provides a kind of twisted polyethylene cable.
To achieve these goals; The technical scheme that the utility model adopts is: a kind of twisted polyethylene cable; Comprise the multiply cable, cable comprises the insulating barrier that wire stylet is outer with being wrapped in conductor, and said insulating barrier comprises double-layer structure; Be followed successively by inner insulating layer and insulating outer layer from inside to outside, the outer wall of said cable is enclosed with watertight composition and armour from inside to outside successively.
As preferably, inner insulating layer is a polyethylene layer, and insulating outer layer is the flame-proof polyvinyl chloride insulating barrier.
As preferably, watertight composition is a PAP.
As preferably, the space between cable and the watertight composition is filled with electro-insulating rubber.
Compared with prior art, the advantage of the utility model is: simple in structure, processing technology is uncomplicated, has two-layer insulating mechanism, reaches fire-retardant purpose, and does not influence the electric property and the thermal stability of product, excellent waterproofness, and the scope of application is extensive.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 11, wire stylet; 12, inner insulating layer; 13, insulating outer layer; 2, electro-insulating rubber; 3, watertight composition; 4, armour.
Embodiment
To combine accompanying drawing that the utility model is described further below.
A kind of execution mode as the utility model; Consult Fig. 1; The utility model comprises the multiply cable, and cable comprises the insulating barrier that wire stylet 11 is outer with being wrapped in conductor, and said insulating barrier comprises double-layer structure; Be followed successively by inner insulating layer 12 and insulating outer layer 13 from inside to outside, the outer wall of said cable is enclosed with watertight composition 3 and armour 4 from inside to outside successively.Inner insulating layer 12 is a polyethylene layer, and insulating outer layer 13 is the flame-proof polyvinyl chloride insulating barrier.Watertight composition 3 is a PAP.Space between cable and the watertight composition 3 is filled with electro-insulating rubber 2.
The utility model is simple in structure, and processing technology is uncomplicated, has two-layer insulating mechanism, reaches fire-retardant purpose, and does not influence the electric property and the thermal stability of product, excellent waterproofness, and the scope of application is extensive.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation in spirit that does not break away from the utility model or the scope in other embodiments among this paper.Therefore, the utility model will can not be limited to these embodiment shown in this paper, but will accord with principle disclosed herein and features of novelty the wideest corresponding to scope.
