Abstract
The utility model relates to a cable and particularly relates to a rated voltage 1KV and 3KV extruded insulation five-core power cable. The cable comprises a core wire and a cable core which is stranded around the core wire and is formed by four subordinate wires. The outer sides of the core wire and the subordinate wires are provided with an insulation layer. A metal sheath is arranged outside the insulation layer. The core wire and the subordinate wires comprise an internal conduction and an insulator arranged at the surface of the conductor. An aluminum foil and a drain wire are respectively arranged outside the cable core. The aluminum foil is connected with the drain wire. According to the rated voltage 1KV and 3KV extruded insulation five-core power cable, through covering the outer side of the cable core with the aluminum foil which is connected with the drain wire, the electromagnetic shielding of the cable core is carried out through the aluminum foil, compared with an insulation layer, the aluminum foil has the advantages of small thickness and good shielding effect, the shielding capacity of the cable can be greatly raised, the interference is reduced, the basic thickness of the cable is not increased, and the applicability of the cable is raised.
Description
Technical field
The utility model relates to a kind of cable, especially a kind of rated voltage 1KV and 3KV extruded insulation 5-core power 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, the scope of application of dwindling cable.
Utility model content
The utility model provides a kind of shield effectiveness that can improve cable, can maintain again rated voltage 1KV and the 3KV extruded insulation 5-core power 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 four 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 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.
