The content of the invention
The technical problem existed based on background technology, the present invention proposes a kind of high lightning protection tension communication electricity of mechanical performance
Cable, to solve above-mentioned technical problem.
A kind of high lightning protection tension communication cable of mechanical performance 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 around the cable
Core center is annularly distributed, and Halogen polyester core body is located between the core, and offsets therewith, and heat absorption packing material is filled at line
Between core and Halogen polyester core body so that the cable core has circular cross-section, and lapping layer is by plastic-aluminum combined Transposed wind described
Cable core periphery is formed, and 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 layer periphery.Core includes the conductor for being located at middle part, insulating barrier and sub-shield that conductor periphery is coated on successively.
Insulating barrier is extruded using polyvinyl chloride and formed, and sub-shield is formed using zinc-plated proof copper-wire braided, and the count of sub-shield is big
In 80%, 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 high lightning protection tension communication cable of mechanical performance proposed by the present invention, when being struck by lightning, ground plane is in short-term
Caloric value is small, reduces the probability that cable core is blown by thunderbolt, and play the function of shielding electromagnetic wave；In the case of thunderbolt, line
Heat absorption packing material between core can be absorbed into heat in core, and the heat produced during absorbable core work, make line
Core temperature will not rise too high, it is ensured that the performance of core；Halogen polyester core body between core possess excellent rigidity,
Impact flexibility and heat resistance, when by 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
Good, power transmission is stable, still can normal work in the case of thunderbolt.
