Abstract
The utility model proposes a kind of high temperature resistant airfield aid optical cable, including several cable cores, the cable core includes copper conductor and the silane type halogen-free and low-smoke flame-retardant polyolefin Insulation Material insulating layer that is arranged in outside copper conductor.It is provided with heat radiating metal pipe at the center of the cable core, coolant liquid is set in the heat radiating metal pipe.The cable core is orderly arranged outside each mica tape flame-retardant layer, inorganic silicon thermal insulation layer, polyacrylate swelling fiber coating polyester water blocking layer, capsaicine protection against rodents layer and low smoke halogen-free flame-retardant polyolefin oversheath, the outer surface of the low smoke halogen-free flame-retardant polyolefin oversheath and is coated with asphalt paint layer.The high temperature resistant airfield aid optical cable of the utility model coats polyester water blocking layer and capsaicine protection against rodents layer by setting heat radiating metal pipe, mica tape flame-retardant layer, inorganic silicon thermal insulation layer, polyacrylate swelling fiber, it is provided simultaneously with excellent heatproof, heat dissipation, fire prevention, waterproof, rodent-proof characteristic, high reliablity, long service life.
Description
Technical field
The utility model relates to a kind of cables, concretely relate to a kind of high temperature resistant airfield aid optical cable.
Background technique
With the Large scale construction on China airport, a large amount of airfield runway aid-to-navigation light and cable matched with its are needed, it is resistance to
High-temperature environmental-protection cable is worked together with lamps and lanterns, light bulb as the secondary connecting line of isolating transformer in the secondary terminals of isolating transformer,
Operating voltage not more than 40V, cable are usually embedded under concrete road surface, mainly by electric power from backbone transport to
Outfield navaid lamps and lanterns, thus cable it is unobstructed whether be directly related to the normal operation of navigational lighting aid system.The electricity of the prior art
Cable heatproof, heat dissipation, fire prevention, waterproof, rodent-proof characteristic have the defects that it is different degrees of, when being used in severe external environment can
It is poor by property.
Utility model content
The utility model proposes a kind of high temperature resistant airfield aid optical cables, are provided simultaneously with excellent heatproof, heat dissipation, prevent
Fire, waterproof, rodent-proof characteristic, high reliablity, long service life.
Technical solution: described the utility model proposes a kind of high temperature resistant airfield aid optical cable, including several cable cores
Cable core includes copper conductor and the silane type halogen-free and low-smoke flame-retardant polyolefin Insulation Material insulating layer that is arranged in outside copper conductor.The cable core
Center at be provided with heat radiating metal pipe, coolant liquid is set in the heat radiating metal pipe.The cable core is orderly arranged outside each mica
Band flame-retardant layer, inorganic silicon thermal insulation layer, polyacrylate swelling fiber coating polyester water blocking layer, capsaicine protection against rodents layer and low smoke and zero halogen
The outer surface of fire retardant polyolefin oversheath, the low smoke halogen-free flame-retardant polyolefin oversheath is coated with asphalt paint layer.
Further, it is additionally provided between the inorganic silicon thermal insulation layer and polyacrylate swelling fiber coating polyester water blocking layer
Steel armor.
Further, the steel armor is coated with erosion resistant coating.
The utility model has the advantages that the high temperature resistant airfield aid optical cable of the utility model passes through setting heat radiating metal pipe, mica tape
Flame-retardant layer, inorganic silicon thermal insulation layer, polyacrylate swelling fiber coating polyester water blocking layer and capsaicine protection against rodents layer, are provided simultaneously with excellent
Good heatproof, heat dissipation, fire prevention, waterproof, rodent-proof characteristic, high reliablity, long service life.
Detailed description of the invention
Fig. 1 is the high temperature resistant airfield aid light construction of cable schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, a kind of high temperature resistant airfield aid optical cable, including several cable cores, the cable core include that copper is led
Body 1 and the silane type halogen-free and low-smoke flame-retardant polyolefin Insulation Material insulating layer 2 being arranged in outside copper conductor 1.At the center of the cable core
It is provided with heat radiating metal pipe 3, coolant liquid is set in the heat radiating metal pipe 3.It is logical that heat radiating metal pipe 3 provides cable rapid cooling
Road improves the heat dissipation performance of cable.
Mica tape flame-retardant layer 4 is set on the outside of the cable core, enhances the fire retardant performance of cable.Outside mica tape flame-retardant layer 4
The inorganic silicon thermal insulation layer 5 of side prevents external high temperature to electric cable heating.The polyacrylate swelling fiber in 5 outside of inorganic silicon thermal insulation layer
Coating polyester water blocking layer 6 prevents cable under the wet environment of underground, steam intrusion corrosion conductor.Polyacrylate swelling fiber
The capsaicine protection against rodents layer 7 for coating 6 outside of polyester water blocking layer, capsaicine can be generated after mouse son gnaws through and is generated strongly to mouse
Stimulation, drives mouse to abandon biting.The low smoke halogen-free flame-retardant polyolefin oversheath Final 8 degree in 7 outside of capsaicine protection against rodents layer is high, simultaneously
It is low to the organ stimulating of people and the corrosion strength of equipment in burning.
Steel is additionally provided between the inorganic silicon thermal insulation layer 5 and polyacrylate swelling fiber coating polyester water blocking layer 6
Armor 9, further increases cable compression strength, and steel armor 9 is also coated with erosion resistant coating.
