Abstract
The utility model relates to a private cable for an airport navigation lamplight circuit and belongs to the technical field of wires and cables. The private cable is characterized in that normally arranged multi-strand round filaments which are subjected to drawing die and compression are twisted to a conductor; a conductor shielding layer, an insulation layer, an insulating shielding layer, a metal shielding layer and a sheath are sequentially arranged at the periphery of the conductors; repousses on the conductors can be eliminated because the conductors are sequentially subjected to drawing die and compression; the conductor shielding layer, the insulation layer and the insulating shielding layer are in tight connection through a three-layer co-extrusion and irradiation crosslinking manner, so that the gaps among the three uniform layers are avoided, the coating effect is good, partial discharge of the cable is reduced; and the mechanical physical property and the electrical performance of insulation of the cable are improved through an extrusion manner. The private cable has the characteristics of superior electrical performance, stronger mechanical strength, superior environmental stress crack resistance, anti-jamming capability and environmental protection.
Description
Technical field
The utility model relates to a kind of cable, relates in particular to a kind of airfield aid light circuit private cable, belongs to technical field of electric wires and cables.
Background technology
Along with China's rapid economic development and country strengthen the dynamics of infrastructure construction; Civil aviation constantly develops, and large quantities of main lines airport and branch line airport be newly-built successively, enlarging and reconstruction, and regional extent is very wide; Especially now the flight order of classes or grades at school is more and more; Aircraft frequently lands, and particularly the night flight flight is more and more, therefore to cable each item performance index of airfield aid photosystem; Electric property, cold resistance, resisting environmental stress and cracking, ageing-resistant performance etc. are had higher requirement, and the stability of airfield aid optical cable directly has influence on the safe operation on aircraft, personal safety and whole airport.
The utility model content
The utility model is to the deficiency that exists in the above-mentioned prior art, and a kind of airfield aid light circuit private cable with good electric property, cold resistance, resisting environmental stress and cracking and very strong mechanical strength properties is provided.
The technical scheme that the utility model solves the problems of the technologies described above is following: a kind of airfield aid light circuit private cable; Comprise conductor; It is characterized in that; Said conductor presses stranded forming by the regular arrangement of multiply circular monofilaments through drawing-die, and said conductor periphery is provided with conductor shield, insulating barrier, insulation screen, metal screen layer and sheath successively
Further, said conductor is 7 bursts of stranded forming of copper cash.
Further, said conductor shield adopts cross-linking radiation conductive shield material, and thickness is not less than 0.15mm.
Further, said insulating barrier adopts the IXPE material, and the insulation nominal thickness is 2.8mm.
Further, said insulation screen adopts cross-linking radiation strippable semi-conductive shielding material, and thinnest part thickness is not less than 0.3mm.
Further, said conductor shield, insulating barrier and insulation screen adopt mode three-layer co-extruded, cross-linking radiation to combine closely.
Further, said metal screen layer adopts that the soft copper band is overlapping puts up wrapped structure, and copper strips thickness is not less than 0.07mm, and the rate of putting up is not less than 15%.
Further, said sheath adopts polythene material, and thickness is 1.4-1.8mm.
The beneficial effect of the utility model is: said conductor presses through drawing-die, and conductive surface is bright and clean, eliminated the conductor burr; Said conductor shield adopts cross-linking radiation conductive shield material; Evenly be coated on conductive surface; Said conductor shield, insulating barrier, insulation screen adopt mode three-layer co-extruded or that 1+2 extrudes; Guaranteed even no gap covered effect between each layer, extruded the back for three layers and insulating material is carried out radiation irradiation processing, the mechanical and physical performance of insulation and electric property have been much improved through cross-linking radiation through electron accelerator; Core by conductor, conductor shield, insulating barrier and insulation screen are formed is combined closely, and the partial discharge of cable has been reduced in no gap to greatest extent; For guaranteeing the accuracy of transmission signals, adopt soft copper band screen, add the rate of putting up of optimization, the problem that has solved shielding and disturbed; Said sheath directly contacts external environment, and consideration cable self performance also will be taken into account the influence of environment to it simultaneously, selects to use cold resisting type, the polythene material of environment-friendly type, resisting environmental stress and cracking type.
