The invention has the beneficial effects of simple structure, convenient use, low comprehensive cost, low smoke content, no toxicity, strong anti-aging ability and stable and reliable operation.
Description
Technical field
The present invention relates to a kind of cable, relate in particular to a kind of green low-carbon environment-friendly anti-aging cotton covered wire.
Background technology
At present, cotton covered wire for building is the individual layer insulation, and its electrical property and ageing resistance are poor, in only 15 years life-span, because cotton covered wire for building is arranged in the building, in case break down, changes comparatively loaded down with trivial details.If the cotton covered wire burning can discharge toxic gas and smoke density is big, serious threat resident's life security.
Summary of the invention
For solving above technical deficiency, the invention provides and a kind ofly have simple in structurely, can effectively improve the green low-carbon environment-friendly anti-aging cotton covered wire of advantages such as cable electrical property and ageing resistance.
The present invention is achieved by the following measures:
A kind of green low-carbon environment-friendly anti-aging cotton covered wire of the present invention, comprise conductor and oversheath, at least one of described conductor, every conductor all is with inner insulating layer and external insulation layer outward, be filled with obturator between external insulation layer and the oversheath, inner insulating layer is made by coupling ethylene propylene rubber, and external insulation layer is made by low smoke and zero halogen irradiation cross-linking flame-retardant polyolefin, oversheath is made by low smoke halogen-free flame-retardant polyolefin, and obturator is a halogen-free low-smoke flame retardant material.
Green low-carbon environment-friendly anti-aging cotton covered wire of the present invention, the coupling ethylene propylene rubber of described inner insulating layer is made by ethylene-propylene rubber, antiaging agent, sulphur and cross-linking radiation agent.
Green low-carbon environment-friendly anti-aging cotton covered wire of the present invention, described external insulation layer are through the external insulation layer behind the gamma-ray irradiation of electron accelerator.
Green low-carbon environment-friendly anti-aging cotton covered wire of the present invention, described conductor are single copper cash or stranded conductor.
The invention has the beneficial effects as follows: integrated cost is low, has guaranteed the stability of properties of product, has reduced electric energy loss in use, makes electric energy transmitting more stable, ensures the electrical property of cable, thereby electric energy can effectively be transmitted; Not combustion-supporting and burning the time does not discharge toxic gas, smoke density is little, has guaranteed the feature of environmental protection of cable; The use of this double-deck heterogeneous cross-linked material has increased the resistance to ag(e)ing of cable, has guaranteed the useful life of cable.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1, conductor; 2, inner insulating layer; 3, external insulation layer; 4, obturator; 5, oversheath.
Embodiment
As shown in Figure 1, green low-carbon environment-friendly anti-aging cotton covered wire of the present invention, originally it comprises at least one conductor 1 and oversheath 5, the outer conductor double insulating layer that is arranged with of every conductor 1, the conductor double insulating layer comprises inner insulating layer 2 and external insulation layer 3; Wherein, inner insulating layer 2 is made by coupling ethylene propylene rubber; External insulation layer 3 is made by low smoke and zero halogen irradiation cross-linking flame-retardant polyolefin, is filled between external insulation layer 3 and the oversheath 5 with the obturator 4 of halogen-free low-smoke flame retardant material, and oversheath 5 adopts the low-smoke halogen-free polyolefin materials to be extruded in into the cable core skin.Also can organize insulated wire cores more and extrude oversheath 5 after stranded.
Insulation Material adopts coupling ethylene propylene rubber and low smoke and zero halogen irradiation cross-linking flame-retardant polyolefin insulation material, coupling ethylene propylene rubber adopts the strong ethylene-propylene rubber of resistance to ag(e)ing to add antiaging agent, for preventing molecule chain rupture in the cross-linking process, improve rate of cure, improve the physical and mechanical properties of vulcanizate, add Sulfur or sulphur-donor and cross-linking radiation agent mixed refining and form, extrude online surface and constitute inner insulating layer 2.After low smoke and zero halogen irradiation cross-linking flame-retardant polyolefin insulation material extruded external insulation layer 3, the gamma-rays by electron accelerator carried out irradiation to the line body, and external insulation layer is crosslinked jointly in making, and had guaranteed the stability of properties of product.Reduced electric energy loss in use, made electric energy transmitting more stable, ensured the electrical property of cable, thereby electric energy can effectively be transmitted; Not combustion-supporting and burning the time does not discharge toxic gas, smoke density is little, has guaranteed the feature of environmental protection of cable; The use of this double-deck heterogeneous cross-linked material has increased the resistance to ag(e)ing of cable, has guaranteed the useful life of cable.
