Abstract
The utility model discloses a backbone cable of a cable television, which comprises an inner conductor, an insulating layer (2), an outer conductor (3) and a protective sleeve (4). The backbone cable of a cable television is characterized in that the inner conductor comprises an aluminum wire (1-1) and a copper layer (1-2) plated on the outer surface of the aluminum wire (1-1), and the outer conductor (3) is an aluminum tube. Due to the adoption of the technical scheme, the inner conductor is the aluminum wires with the copper layer plated on the outer surface so as to greatly reduce the consumption of copper and improve the economy of the cable. Meanwhile, the specific gravity of copper and aluminum is 3.3 so as to reduce the weight of the product.
Description
Technical field
The utility model relates to a kind of coaxial TV cable, in particular for the camera cable of backbone.
Background technology
At present, the cable that is used for the cable TV backbone generally is made up of inner wire, insulating barrier, outer conductor, sheath, and inner wire is a copper cash, and outer conductor is a copper pipe.This kind cable copper product consumption height because the copper material price rapidly goes up at present, causes enterprise's production cost to increase greatly, so this cable shortage economy, and the proportion of copper is bigger simultaneously, uses the tensile strength that needs to improve it as backbone.
Summary of the invention
The purpose of this utility model is in order to overcome the defective of prior art, low, the lightweight cable TV backbone of a kind of cost cable to be provided.
In order to realize the purpose of this utility model, adopted following technical scheme: a kind of cable TV backbone cable, comprise inner wire, insulating barrier, outer conductor, sheath, it is characterized in that inner wire forms by aluminum steel with at the layer of copper layer of aluminum steel outer surface plating, described outer conductor is an aluminum pipe.
Further, described insulating barrier is a polyethylene layer.
Further, described sheath is a pe sheath.
Because having adopted technique scheme, inner wire is the aluminum steel that outer surface is coated with the copper layer, the consumption of copper significantly reduces, and this cable economy is improved; The heavy ratio of copper aluminum ratio is 3.3 simultaneously, so the utility model product weight is alleviated.
Description of drawings
Accompanying drawing is a structure chart of the present utility model.
Among the figure: 1-1, aluminum steel, 1-2, copper layer, 2, insulating barrier, 3, outer conductor, 4, sheath.
Embodiment
Among the embodiment as shown in the figure, a kind of cable TV backbone cable, inner wire is formed by aluminum steel 1-1 with at the layer of copper layer 1-2 of aluminum steel 1-1 outer surface plating, be insulating barrier 2, outer conductor 3, sheath 4 successively outside inner wire, insulating barrier 2 is polyethylene layers, outer conductor 3 is an aluminum pipe, and sheath 4 is pe sheaths.
Claims (3)
1, a kind of cable TV backbone cable, comprise inner wire, insulating barrier (2), outer conductor (3), sheath (4), it is characterized in that inner wire forms by aluminum steel (1-1) with at the layer of copper layer (1-2) of aluminum steel (1-1) outer surface plating, described outer conductor (3) is an aluminum pipe.
2, cable TV backbone cable according to claim 1 is characterized in that described insulating barrier (2) is a polyethylene layer.
3, cable TV backbone cable according to claim 1 and 2 is characterized in that described sheath (4) is a pe sheath.
