Abstract
The invention relates to a compound crosslinked polyethylene insulated aerial cable which belongs to the technical field of a cable material. The compound crosslinked polyethylene insulated aerial cable comprises a cable core, a shielding layer and an insulating layer; a crosslinked polyethylene main insulating layer and a weather-proof crosslinked polyethylene outer insulating layer are arranged outside the shielding layer in sequence; and the shielding layer, the main insulating layer and the outer insulating layer are molded by co-extruding. The compound crosslinked polyethylene insulated aerial cable has excellent insulating performance; no insulator is needed during laying the cable; and by the cable, the thickness of the insulating layer can be reduced, the polyethylene (petrochemical) material is saved, and the engineering production cost is reduced.
Description
Technical field
The present invention relates to a kind of aerial insulated cable, belong to the CABLE MATERIALS technical field, refer in particular to a kind of crosslinked polyethylene insulated aerial cable that adopts composite insulation layer.
Background technology
What at present, the insulation system of domestic being seen crosslinked polyethylene insulated aerial cable was that individual layer has a weather resistance crosslinked polyetylene insulatedly is insulating barrier.Owing to be mixed with the carbon black that absorbs the terrestrial solar radiation energy in the crosslinked material of weather-proof crosslinked polyethylene, make the insulating capacity of insulating barrier descend, showing has leakage current to produce.Under the leakage current inflow place, cause the loss of voltage, support place must be used insulator when laying.
Summary of the invention
The present invention provides a kind of aerial insulated cable with excellent insulation property just in order to overcome above-mentioned deficiency.The main improvement is insulation layer structure is combined by the crosslinked polyethylene insulation material that traditional single insulating material changes the same base-material of employing, difference in functionality into, promptly based on the insulating barrier of insulation function with to prevent the auxiliary insulating layer of the aging function of daylight, main insulating layer adopts the cross-linked polyethylene insulating material of high insulating property, auxiliary insulating layer to adopt the crosslinked insulating material of anti-solar radiation that is added with carbon black, adopts three-layer co-extruded technology to extrude screen, main insulating layer, the insulating barrier of anti-the solar radiation simultaneously.It specifically is to implement like this: compound crosslinked polyethylene insulated aerial cable, comprise core, screen, insulating barrier, it is characterized in that screen is provided with crosslinked polyethylene main insulating layer and weather-proof crosslinked polyethylene external insulation layer outward successively, described screen, main insulating layer, external insulation layer are three-layer co-extruded moulding.
Adopt the aerial cable of composite insulation structure, have excellent insulation property, can be when laying without insulator, thickness that simultaneously can the attenuate insulating barrier has been saved polyethylene (petrochemical industry) material, has reduced the engineering production cost.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
Embodiment
The aerial cable of composite insulation structure: adopt three-layer co-extruded technology, outside core 1, extrude simultaneously: conductor shield 2, crosslinked polyethylene main insulating layer 3, the weather-proof crosslinked polyethylene external insulation layer of anti-irradiation 4.
