Description
Technical field
The utility model relates to power transmission technology field, particularly relates to a kind of heat radiating type power cable.
Background technology
Core meeting generation current heat led by wire in galvanization, when wire is thick not by wire for big current, will produces a large amount of heats, destroy the insulation property of wire, cause line short, cause electric fire.
Utility model content
Based on the technical problem that above-mentioned background technology exists, the utility model proposes a kind of heat radiating type power cable, make to lead the conduct heat away that core produces in running and go out, avoid the insulation property of electrical current heat to insulating barrier to impact, improve the fail safe of cable.
The utility model proposes a kind of heat radiating type power cable, comprise: lead core, insulating barrier, screen and outer jacket, wherein, the periphery of leading core is coated with the first lapping layer, by heat proof material, along leading, core is laterally wrapped to be formed first lapping layer, the periphery of the first lapping layer is provided with multiple heat-dissipating cylinder, on the arbitrary cross section of power cable, each heat-dissipating cylinder along the first lapping layer outer peripheral face annular spread and fit with the outer peripheral face of the first lapping layer, leave gap between each heat-dissipating cylinder, in the gap between heat-dissipating cylinder, be filled with interlayer filler; The axial plane of heat-dissipating cylinder is distributed with some louvres, and each heat-dissipating cylinder entirety is coated with the second lapping layer, and the second lapping layer is formed along the overall periphery of each heat-dissipating cylinder is laterally wrapped by heat-barrier material; Insulating barrier is coated on the periphery of the second lapping layer, and screen is coated on the periphery of insulating barrier, and outer jacket is coated on the periphery of screen.
Preferably, the material of the first lapping layer is mica tape.
Preferably, the material of the second lapping layer is ceramic fiber cloth.
Preferably, interlayer filler is alkali-free glass fiber dimension.
In the utility model, in the periphery of leading core, coated first lapping layer, arranges multiple heat-dissipating cylinder in the periphery of the first lapping layer, and is distributed with some louvres on the axial plane of heat-dissipating cylinder; Heat dissipating layer is formed leading between core and insulating barrier by heat-dissipating cylinder, lead the electrical current heat that core operationally produces and enter heat dissipating layer, dispersing of heat is carried out by heat-dissipating cylinder, avoid the excessive decreasing insulating causing insulating barrier of electrical current heat, thus reduce the probability that line short occurs because of the insulating properties destruction of insulating barrier, improve the fail safe of cable.
Accompanying drawing explanation
