Abstract
The utility model relates to a buried cable for an airport navigation light loop. An inner shielding layer, an insulating layer and an outer shielding layer are extruded on a conductor by production methods of three-layer co-extrusion, dry-process cross linking and continuous vulcanization. The conductor, the inner shielding layer, the insulating layer and the outer shielding layer are combined to form an insulating wire core. A copper belt shielding layer is lapped at the periphery of the insulating wire core. An outer sheath is extruded at the periphery of the copper belt shielding layer. The utility model has the advantages of providing a 5 kV buried cable for an airport navigation light loop, which is fine in electric property, can guarantee stable and long-term power use for airfield runways, and provides reliable illumination effect for aircrafts.
Description
Technical field
The utility model relates to a kind of 5kV airfield aid light circuit buried cable, belongs to technical field of electric wires and cables.
Background technology
The airfield aid optical cable is used for the electric power transfer of Civil Aviation Airport with the light navigation system, and the stability of cable directly has influence on the fail safe of flight landing.Along with the develop rapidly of World Economics, the flight order of classes or grades at school is more and more, and the flight landing is more and more frequent, to having higher requirement in the stability and the useful life of airfield aid optical cable.In addition, along with the airport construction zone enlarges, coastal to south from northern borderland, each airport environment is not the same, and is also inequality to the requirement of cable.
Summary of the invention
The purpose of this utility model provides a kind of good electric property, can satisfy various environmental requirements, guarantees the stably long-time electricity consumption of airfield runway, the 5kV airfield aid buried cable of reliable illuminating effect can be provided for aircraft.
The technical solution of the utility model is: the mode of production with three-layer co-extruded, dry cross-linking, continuous vulcanization on conductor extrudes internal shield, insulating barrier and outer shielding layer.Conductor, internal shield, insulating barrier and outer shielding layer are formed insulated wire cores.At the peripheral wrapped copper strips screen of insulated wire cores.Extrude oversheath in copper strips screen periphery.
Described conductor adopts metric wire gage, by 7 external diameters stranded forming of copper cash that be 1.04mm.
Described internal shield is selected semi-conductive shielding material for use, and minimum thickness is 0.15mm.
Described insulating barrier is selected crosslinked polyethylene (XLPE) material or waterproof tree crosslinked polyethylene (TRXLPE) material or ethylene-propylene rubber (EPR) material for use.Thickness of insulating layer is 2.16mm-3.05mm.
Described outer shielding layer is selected semiconductive insulation shielding material for use, and minimum thickness is 0.30mm.
Described copper strips screen adopts overlapping wrapped structure.Copper strips thickness is 0.07mm～0.10mm.
Described oversheath is selected pe sheath or polyvinyl chloride thermoplastics type sheath or cross-linking type neoprene sheath for use, and external sheath layer thickness is 1.4mm～1.8mm.
The utility model is to be specifically designed to 5kV airfield aid light circuit buried cable, and it can require to select for use different insulation, sheath material according to different environments for use, operating characteristic.Adopt three-layer co-extruded, dry cross-linking, the disposable insulated wire cores of producing of the continuous vulcanization mode of production, do not have impurity to bring insulated wire cores in the time of guaranteeing to produce.The copper strips screen can be limited to electric field in the insulation, prevents the axial surface discharge, has the effect of magnetic screen.Can guarantee effectively that like this cable can be stablized long-play under airfield runway usefulness 5kV voltage, the outside diameter of cable is little, and is in light weight.
The utility model has the advantages that provides a kind of good electric property, can guarantee the stably long-time electricity consumption of airfield runway, the 5kV airfield aid light circuit buried cable of reliable illuminating effect is provided for aircraft.
