2, cable does not possess excellent electric property, and there is limitation in territory of use, and cable is short useful life in addition.
Because cable often is subject to mouse and termite bites, can not normally use.Cable does not have good waterproof sheath in addition, and useful life is short, and due to the needs of the round-the-clock landing of aircraft, except radar guided, airfield runway must have obviously stable and interference-free lamplight pointing, to guarantee aircraft accurate landing safe against all possibilities.The navaid cable supporting with it has high-performance and high reliability is also vital.
Because traditional cable often is subject to mouse and termite bites, cause sheath to damage or water inlet, add that the insulation water tree resistant property is poor, therefore cable uses and has unsafe factor, and useful life is short, and this just need to develop the novel buried cable for airport flight assistant lamp light circuit that can really conform and need as early as possible.
Summary of the invention
Technical problem to be solved in the utility model is to provide the buried environment-friendly cable of a kind of airfield aid light circuit, can solve the problem of using under particular surroundings, and is safe and reliable to operation, long service life.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the buried environment-friendly cable of a kind of airfield aid light circuit, copper conductor are enclosed with conductor shield, insulating barrier, insulation screen, copper strip shielding layer, water blocking layer, composite bed and external sheath layer outward successively.
Insulating barrier is the crosslinked polyetylene insulated layer of water resistant tree.
Water blocking layer is the waterstop coating layer, is preferably double-sided aluminum plastic composite band coating layer.
Composite bed is the aluminium-plastic tape coating layer.
External sheath layer is the anti-ant high density polyethylene (HDPE) restrictive coating of environment protection, rat.
Copper conductor is circular compact conductor.
The buried environment-friendly cable of the airfield aid light circuit that the utility model provides, beneficial effect is as follows:
1, conductor adopts circle to press mode, and the cable conductor nominal cross is 6mm 2, the D.C. resistance of conductor in the time of 20 ℃≤3.08 Ω/km; Insulating barrier adopts the crosslinked polyetylene insulated layer of water resistant tree, and water tree resistant property is excellent; Water blocking layer vertical bag one deck aluminium-plastic tape outward is used for reaching the comprehensive waterproof purpose; External sheath layer adopts the anti-ant high density polyethylene (HDPE) restrictive coating of environment protection, rat, has excellent water resistant tree property, waterproof, termite-resistant rodent-resistant integrated protection performance.
2, through cable is tested, result shows that the cable property indices is excellent, all meets designing requirement, can be widely used in the navigational lighting aid loop on domestic each large airport.Compare with traditional cable, the construction of cable is novel, and the electric property of cable and physical property are excellent, waterproof, termite-resistant rodent-resistant integrated protection excellent performance.Cable is safe and reliable, the life-span is long, can fixedly be embedded in humidity and damaged by rats, ant evil area.Cable body has environment-friendly type, does not exist environment, and is safe and reliable, the life-span is long, can fixedly be embedded in the humid area.
