Brief description of the drawings

The utility model is described in further detail with reference to the accompanying drawings and detailed description.

Fig. 1 is the cross section structure schematic diagram of the utility model cable.

Embodiment

As shown in Figure 1, the utility model cable includes sheath 1, some insulated wire cores are provided with the sheath 1, should Insulated wire cores include conductor 21 and the insulating layer of conductor 22 being covered in outside conductor 21, the outer surface of the insulating layer of conductor 22 It is additionally provided with semiconducting material 23,23 electrical communication of semiconducting material of above-mentioned some insulated wire cores.

Specifically, as shown in Figure 1.The utility model cable includes sheath 1, insulated wire cores, cotton yarn 3 and aerial drainage conducting wire 4.

In this embodiment, the quantity of insulated wire cores is three.Insulated wire cores include conductor 21 and are covered in Insulating layer of conductor 22 outside conductor 21, the outer surface of the insulating layer of conductor 22 are additionally provided with semiconducting material 23.It is above-mentioned Mutual reliable contacts are to realize electrical communication between the semiconducting material 23 of three insulated wire cores.

Sheath 1 is wrapped in outside above-mentioned three insulated wire cores, it is used for realization the protection to insulated wire cores.

In traditional design, external world's formation electromagnetism is done in the magnetic field that the insulated wire cores inside cable produce after being powered in order to prevent Disturb, and the interference for preventing external magnetic field to be powered cable built-in electrical insulation core, the bread usually outside the insulating layer of insulated wire cores One layer of aluminium foil is wrapped up in, to realize electromagnetic shielding.But this mode make it that cables manufacturing is of high cost, and multiple tracks is needed to process work in production Sequence.

In the design, semiconducting material 23 is enclosed with the outside of insulating layer of conductor 22 to realize the electricity to insulated wire cores Magnetic screen.23 material therefor of semiconducting material is specially semiconductive PVC, but not limited to this, its also can use semiconductive PE, The material such as semiconductive PO and semiconductive PP.Compared to aluminium foil, semiconductive PVC cost is cheaper.Ensureing good electric conductivity While, semiconductive PVC causes cable to reduce multi-step process when being processed, and considerably reduces the manufacture of cable Cost.

Aerial drainage conducting wire 4 is additionally provided between sheath 1 and insulated wire cores, which can with semiconducting material 23 By contacting to realize electrical communication.

This cable is connected to leakage monitoring device in practical applications, by aerial drainage conducting wire 4.Due to 23 energy of semiconducting material It is enough that delicately the capacitance current of insulated wire cores or leakage current are delivered in aerial drainage conducting wire 4, and then by aerial drainage conducting wire 4 by electricity Capacitance current either leakage current be delivered to leakage monitoring device so as to fulfill to insulated wire cores to capacitance current or leakage current can By monitoring.

In this embodiment, semiconducting material 23 is set to insulated wire cores insulating layer 5 in the form of extruding Outside.Semiconducting material 23 is peelable type in order to wiring.

In order to strengthen the endurance of cable, and realize the protection to insulated wire cores, filled between sheath 1 and insulated wire cores Cotton yarn 3.

The foregoing is merely the preferred embodiments of the utility model, as long as realizing the utility model with essentially identical means The technical solution of purpose is belonged within the scope of protection of the utility model.
