Embodiment
Self-supporting 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 of self-supporting lightning-proof power cable of the present invention, and Fig. 2 has shown second embodiment of self-supporting lightning-proof power cable of the present invention.In first embodiment, self-supporting lightning-proof power cable has two and thoroughly does away with edge core 1.In a second embodiment, self-supporting lightning-proof power cable has three eradication edge cores 1.
Put it briefly, self-supporting 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; And
The messenger wire 10 that connects described coating;
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.
Characteristics of the present invention are, be provided with a messenger wire 10 that connects coating, so that can utilize the messenger wire of self to set up power cable, not only can accelerate to suppose power cable speed, the expense of the messenger wire that independently is used to carry power cable save to be set, and can also improve the anti-mechanical stretch ability of cable, thereby the communication security of support equipment.
As Fig. 1 or shown in Figure 2, messenger wire 10 comprises: the cable wire 101 that is used to carry; With the messenger wire overcoat 102 that coats described cable wire 101; Wherein said messenger wire overcoat 102 is structure as a whole with described oversheath 8, thereby realizes being connected of oversheath 8 of messenger wire overcoat 102 and power cable.
