Description
Technical field
The utility model relates to a kind of power transmission and distribution field, specifically, relates to a kind of concentric conductor shielding power cable.
Background technology
Along with the extensive use of automatic control technology and computer technology, for example: intelligent building, its quality and requirement to the service cable circuit is more and more higher; Simultaneously, the environment that lays of cable line also becomes increasingly complex, and the phase mutual interference is also more and more serious.Traditional lv power cable, especially unarmored cable, owing to there is not shielding construction, therefore, the antijamming capability of cable is relatively poor.Adopt traditional shielding and sheathed structure, the external diameter of cable and manufacturing cost must increase, and the increase of the outside diameter of cable, return laying of cable and bring difficulty.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of antijamming capability is strong, low cost of manufacture, external diameter is little and lay the power cable of concentric conductor shielding easily.
The technical scheme that realizes above-mentioned purpose is: a kind of concentric conductor shielding power cable, comprise conductor wire core, be extruded in the insulating barrier on conductor wire core top layer, packed layer, twining package tape, inner covering, armour and oversheath, described twining package tape is intertwined the many single conductor wire cores that extruded insulating barrier, twining package tape is that spiral twines, the space that twining package tape and insulating barrier surrounded is a packed layer, the twining package tape top layer is coated with inner covering, the skin of described inner covering is an oversheath, has armour between inner covering and the oversheath, its improvement is: also comprise concentric conductor, described concentric conductor is wrapped in the inner covering outer surface, and concentric conductor is filled in the gap of armour winding.
Described concentric conductor evenly arrange with armour and winding direction identical.
Described concentric conductor and armour adjacent spaces are successively arranged.
Described armour is zinc-coated wire or aluminium-clad steel wire.
Described conductor wire core is three, and concentric conductor is a neutral conductor.
Described conductor wire core is four, and concentric conductor is the ground connection core.
Described packed layer is a polymer material layer.
Described twining package tape is the insulating polymeric material band.
The beneficial effects of the utility model are: because cable also comprises concentric conductor, described concentric conductor is wrapped in the inner covering outer surface, and concentric conductor is filled in the gap of armour winding, concentric conductor and armour constitute one deck jointly, form the concentric conductor screen of holding concurrently, the gap that concentric conductor twines replenishes armouring wire as filling, make the common one deck that constitutes of concentric conductor and armour coat whole cable core, form a complete shield, therefore, the shielding that this structure is disturbed to external world is good, also avoids simultaneously self cable line to produce interference to external world, and promptly antijamming capability is strong; Armour evenly arrange with concentric conductor and winding direction identical, safe and reliable to operation so the construction of cable is stable, more guaranteed the shielding of disturbing to external world; Construction of cable compactness, external diameter is little, and product is easily manufactured, technical maturity, low cost of manufacture; Cable installation is also very convenient.
