Abstract
The utility model relates to a single core flame retardation-type power cable comprising a conductor. An insulating layer is arranged outside the conductor. An oxygen isolation layer is arranged outside the insulating layer. A shielding layer is arranged outside the oxygen isolation layer. A foil polyester film layer is arranged outside the shielding layer. An impact-resistant layer is arranged outside the foil polyester film layer. An outer sheath layer is arranged outside the impact-resistant layer. The single core flame retardation-type power cable of the utility model is good in insulation effect, ideal in flame retardation, not easy to damage, and long in usage life.
Description
Technical field
The utility model relates to a kind of cable, is specifically related to a kind of single-core cable.
Background technology
Along with the fast development of national economy, as the aortal electric wire of national economy, its consumption and the scope of application are increasing.In recent years, the industries such as power plant, transformer station, smelting and petrochemical industry, very big to the demand of cable.Power cable is for transmission and distributes the power transmission line of electric energy, be usually used in Urban Underground electrical network, power station lead line, industrial and mining enterprises in-line power and cross river, the submarine transmission line in sea excessively, be specifically designed in addition the electric wire in the places such as subway tunnel, light rail.
At present, most of power cable exists useful life short, and the ordinary maintenance amount is large, and insulation effect is bad, and flame retardant effect is poor, and the oversheath cracky can not meet instructions for use.
Summary of the invention
Goal of the invention: the purpose of this utility model is in order to overcome deficiency of the prior art, provides a kind of insulation effect good, fire-retardant ideal, cracky not, the uni-core flame-retardant type power cable of long service life.
Technical scheme: in order to solve the problems of the technologies described above, a kind of uni-core flame-retardant type power cable described in the utility model, it comprises conductor, be provided with insulating barrier in described conductor outside, be provided with oxygen barrier layer in described insulating barrier outside, in described oxygen barrier layer outside, be provided with screen, in described screen outside, be provided with paper tinsel polyester rete, be provided with anti-impacting layer in described paper tinsel polyester rete outside, in described anti-impacting layer outside, be provided with external sheath layer.
Described conductor is copper conductor or aluminium conductor or tinned copper conductor.
Described insulating barrier is polyvinyl chloride layer or perfluoroethylene-propylene layer.
Described external sheath layer is halogen-free and low-smoke flame-retardant polyolefin sheathed layer.
Beneficial effect: compared with prior art, its remarkable advantage is the utility model: the utility model compact overall structure is connected between each layer, reliable, adopt the perfluoroethylene-propylene insulating barrier, play good insulation effect, adopt oxygen barrier layer, can play good fire retardation, adopt anti-impacting layer, can improve shock resistance, adopt halogen-free and low-smoke flame-retardant polyolefin sheathed layer, can play good protective action, this product whole service life is longer, realistic instructions for use.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein:
1, conductor; 2, insulating barrier; 3, oxygen barrier layer; 4, screen; 5, paper tinsel polyester rete; 6, anti-impacting layer; 7, external sheath layer
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 1, a kind of uni-core flame-retardant type power cable described in the utility model, it comprises conductor 1, be provided with insulating barrier 2 in described conductor 1 outside, be provided with oxygen barrier layer 3 in described insulating barrier 2 outsides, in described oxygen barrier layer 3 outsides, be provided with screen 4, in described screen 4 outsides, be provided with paper tinsel polyester rete 5, be provided with anti-impacting layer 6 in described paper tinsel polyester rete 5 outsides, in described anti-impacting layer 6 outsides, be provided with external sheath layer 7; Described conductor 1 is copper conductor or aluminium conductor or tinned copper conductor; Described insulating barrier 2 is polyvinyl chloride layer or perfluoroethylene-propylene layer; Described external sheath layer 7 is halogen-free and low-smoke flame-retardant polyolefin sheathed layer.The utility model compact overall structure, be connected between each layer, reliable, adopt the perfluoroethylene-propylene insulating barrier, play good insulation effect, adopt oxygen barrier layer, can play good fire retardation, adopt anti-impacting layer, can improve shock resistance, adopt halogen-free and low-smoke flame-retardant polyolefin sheathed layer, can play good protective action, this product whole service life is longer, realistic instructions for use.
The utility model provides a kind of thinking and method; method and the approach of this technical scheme of specific implementation are a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art, under the prerequisite that does not break away from the utility model principle, can also make some improvements and modifications; these improvements and modifications also should be considered as protection range of the present utility model, in the present embodiment not clear and definite each part all available prior art realized.
