Difference, when being struck by lightning, the cable core in it is easily blown, and has a strong impact on the popularization of cable with using.
The content of the invention
The technical problem existed based on background technology, the present invention is proposed a kind of lightning protected cable, asked with solving above-mentioned technology
Topic.
A kind of lightning protected cable of high mechanical strength proposed by the present invention, including：Cable core, lapping layer, ground plane, total screen layer
And oversheath；Cable core includes four cores, Halogen polyester core body and heat absorption packing material, and four cores are in around the cable core center
Annular distribution, Halogen polyester core body is located between the core, and offsets therewith, and heat absorption packing material is filled at core and Halogen
Between polyester core body so that the cable core has circular cross-section, and lapping layer is by plastic-aluminum combined Transposed wind in the cable core periphery
Formed, ground plane is wrapped in the lapping layer periphery, and total screen layer is coated on ground plane periphery, and oversheath is coated on total screen
A layer periphery is covered, ground plane is formed using many stranded copper wires are wrapped, and total screen layer is formed using steel wire and proof copper-wire braided.
A kind of lightning protected cable proposed by the present invention, when being struck by lightning, ground plane short-time thermal amount is small, reduce cable core because
Be struck by lightning the probability being blown, and plays the function of shielding electromagnetic wave；In the case of thunderbolt, the heat absorption packing material energy between core
Heat in core, and the heat produced during absorbable core work are enough absorbed into, core temperature is not risen too high, it is ensured that
The performance of core；Halogen polyester core body between core possesses excellent rigidity, impact flexibility and heat resistance, by
During external stress, it can buffer most of active force by the elastic deformation of itself so that core is not susceptible to disconnected core, it is ensured that
The stabilization of power transmission.Heat-resisting lightning protection control cable proposed by the present invention, tensile property is good, and power transmission is stable, in thunderbolt feelings
Still can normal work under condition.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the lightning protected cable of high mechanical strength proposed by the present invention.
Embodiment
As shown in figure 1, Fig. 1 is a kind of structural representation of the lightning protected cable of high mechanical strength proposed by the present invention.
Reference picture 1, a kind of lightning protected cable of high mechanical strength proposed by the present invention, including：Cable core, lapping layer 4, ground plane
5th, total screen layer 6 and oversheath 7；Cable core includes four cores 1, Halogen polyester core body 2 and heat absorption packing material 3, four cores 1
Annularly it is distributed around the cable core center, Halogen polyester core body 2 is located between the core 1, and offsets therewith, heat absorption filling material
Material 3 is filled between core 1 and Halogen polyester core body 2 so that the cable core has circular cross-section, and lapping layer 4 is by plastic-aluminum combined
Transposed wind is formed in the cable core periphery, and ground plane 5 is wrapped in the periphery of lapping layer 4, and total screen layer 6 is coated on ground plane
5 peripheries, oversheath 7 is coated on the periphery of total screen layer 6.
The cable of the present embodiment is when being struck by lightning, and the short-time thermal amount of ground plane 5 is small, reduces cable core because thunderbolt is blown
Probability, and play shielding electromagnetic wave function；In the case of thunderbolt, the heat absorption packing material 3 between core 1 can be absorbed into
Enter heat in core 1, and the heat produced during the absorbable work of core 1, the temperature of core 1 is not risen too high, it is ensured that line
The performance of core；Halogen polyester core body 2 between core 1 possesses excellent rigidity, impact flexibility and heat resistance, by outer
During portion's stress, it can buffer most of active force by the elastic deformation of itself so that core 1 is not susceptible to disconnected core, it is ensured that
The stabilization of power transmission.
Core 1 in the present embodiment includes the conductor 11 for being located at middle part, the insulating barrier 12 for being coated on the periphery of conductor 11 successively
With sub-shield 13, insulating barrier 12 is extruded using polyvinyl chloride and formed, and possesses good mechanical performance, sub-shield 13 is using plating
Zinc proof copper-wire braided is formed, and the count of sub-shield 13 is more than 80%, and sub-shield 13 is not oxidizable, and light soft.
Ground plane 5 is formed using many stranded copper wires are wrapped, and ground plane 5 possesses enough mechanical strengths, outer receiving
During portion's stress, fracture is not susceptible to, it is ensured that its lightning protection properties.
Total screen layer 6 is formed using steel wire and proof copper-wire braided, during electromagnetic wave signal outside shielding, improves cable
Tensile strength.
Heat-resisting lightning protection control cable proposed by the present invention, tensile property is good, and power transmission is stable, still may be used in the case of thunderbolt
Normal work.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art the invention discloses technical scope in, technique according to the invention scheme and its
Inventive concept is subject to equivalent substitution or change, should all be included within the scope of the present invention.
