On outer wall, external shielding layer and fiber braiding layer, and the fibrage are provided between the PVC protective cases and PVC insulating layers
Layer is arranged between external shielding layer and PVC protective cases.
Further, the gap filling between the heat-conducting metal silk and conducting wire group has heat-resisting asbestos layer.
Further, steel wire reinforcing rib is provided between the fiber braiding layer and PVC protective cases, and the steel wire is reinforced
Muscle winds around the surrounding of fiber braiding layer.
Further, the outer surface of the PVC protective cases is coated with India rubber layer.
Compared with prior art, the utility model has the beneficial effects that：
（1）The utility model reduces the possibility of cable local discharge, keeps away by the way that internal shield and external shielding layer is arranged
Exempt from electric jamming, ensure that the stabilization of cable work performance；
（2）The utility model realizes the good heat sinking function of cable, avoids tradition by the setting of heat-conducting metal silk
The bad limitation current-carrying capacity of cable of cable heat dissipation effect；
（3）For the utility model by the way that fiber braiding layer is arranged, compression strength and the tear-proof for greatly strengthening the cable are strong
Degree, plays protective effect to cable, extends the service life of the cable.

Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
As shown in Figure 1, the utility model provides a kind of electrical equipment polyvinyl chloride cable, including several conducting wires
Group 1, conducting wire group 1 is made of several independent conducting wires, and the outer surface of conducting wire group 1 is coated with PVC insulating layers 2, and the PVC is exhausted
The outer wall of edge layer 2 is provided with PVC protective cases 3, PVC, as polyvinyl chloride, and polyvinyl chloride has stable insulation, fire-retardant effect
The good advantage of fruit substantially increases the service life and universal performance of the cable.
It is provided with internal shield 4 between the PVC insulating layers 2 and conducting wire group 1, since conducting wire group 1 is twisted by multiple conducting wires
Made of conjunction, so being easy to form air gap between PVC insulating layers 2 and conducting wire group 1, conductive surface is rough, can cause electric field
Concentrate, pass through be arranged internal shield 4, you can with realize it is good between PVC insulating layers 2 and conducting wire group 1 contact, to eliminate lead
The increase of Electric Field Indensity on Surface of Conductor caused by body is rough.
