Description
Technical field
The utility model relates to a kind of cable, and especially a kind of specified 450 and 750V fluoroplastic insulation and sheath high temperature resistance control cable.
Background technology
Five core plastic insulating power cables, through the development of nearly more than ten years, have become the important component part of 1kV plastic insulated cable, and have applied from key construction project and cities and towns skyscraper, develop in low voltage power distribution network and use in a large number.
Along with the applied environment of existing 5-core power cable is more and more extensive, requirement to electromagnetic shielding and intensity is more and more higher, the effect that existing cable carries out interference shielding by insulation rubber does not often reach and its effect, and the insulation film damage of easily receiving external force, existing solution is in the outside metallic sheath that increases of cable, the effect of being carried out electromagnetic shielding and being improved intensity aspect by metallic sheath.In order to strengthen shield effectiveness, often realize by the insulate thickness of rubber or metallic sheath of increase, can increase like this cable integral diameter, dwindle the scope of application of cable, and insulation rubber be macromolecule combustible material, in the time that cable temperature is higher, easily burn, safety in utilization reduces.
Utility model content
The utility model provides a kind of shield effectiveness that can improve cable, can maintain again specified 450 and 750V fluoroplastic insulation and sheath high temperature resistance control cable of its applicability.
To achieve these goals, the utility model adopts following technical scheme:
Comprise a heart yearn and stranded in the cable core of heart yearn many subordinate line compositions around, described heart yearn and subordinate line outside are provided with an insulating barrier, insulating barrier outside is provided with a metallic sheath, described heart yearn and subordinate line comprise inner conductor and are located at the insulator of conductive surface, its improvement is: described insulating barrier is fluoroplastic layer, described cable core is respectively equipped with an aluminium foil and a drain wire outward, and described aluminium foil is connected with drain wire.
Preferably, described aluminium foil is one side clad aluminum foil.
Preferably, described one side clad aluminum foil metal level is located at inwall.
Preferably, described metallic sheath inwall is provided with non-hygroscopic nonmetal tearing layer.
Preferably, between described cable core and insulating barrier, be provided with one or more layers non-hygroscopic band.
Preferably, the coated coincidence factor of described aluminium foil is greater than 25%.
Preferably, described aluminum foil thickness is more than or equal to 0.012mm.
Preferably, described drain wire diameter is more than or equal to 0.5mm.
