Embodiment
Lightning-proof power cable of the present invention is a kind of lightning protection and can strengthens cable intensity power cable.
Fig. 1 has shown first embodiment that the lightning-proof power cable of reinforced layer is arranged of the present invention, and Fig. 2 has shown second embodiment of lightning-proof power cable of the present invention.In first embodiment, lightning-proof power cable has two and thoroughly does away with edge core 1.In a second embodiment, lightning-proof power cable has three eradication edge cores 1.
Put it briefly, lightning-proof power cable of the present invention comprises:
The coating of the cable core 9 of transferring electric power and the described cable core 9 of lining;
Wherein, described coating comprises:
Shield the screen 7 of described cable core 9;
Coat the outer belting layer 5 of described screen 7;
Coat the oversheath 8 of described outer belting layer 5; And
Be arranged on the ground plane 4 between described cable core 9 and the described screen 7.
Can adopt various ways to form ground plane 4,, perhaps utilize wire netting to form ground plane such as utilizing metal level to form ground plane.
The present invention preferentially selects to utilize bundle strand copper wire to form ground plane, just ground plane 4 is configured to: by the oblique wrapped described cable core 9 of bundle strand copper wire of stranded copper wire bundle strand, its lay of lapping is 18～28 times of described conductor assembly outer diameter.
Because ground plane is set in power cable, therefore increased the anti-thunderbolt ability of power cable, like this when thunderbolt takes place, ground plane moment just can import the earth rapidly with the thunder and lightning that enters cable, thereby guarantees the safety of power cable and the base station equipment that is connected power cable.
In addition, the present invention with outer belting layer 5 and the following interior belting layer 3 that will illustrate as reinforced layer, so that increase the intensity of cable.
More particularly, the lightning-proof power cable that provides of first embodiment shown in Figure 1 of the present invention comprises:
