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 insulated cores 1.In a second embodiment, self-supporting lightning-proof power cable has three insulated cores 1.
Put it briefly, self-supporting lightning-proof power cable of the present invention comprises:
The cable core 9 of transferring electric power and the coating of the said cable core 9 of lining; And
The messenger wire 10 that connects said coating;
Wherein, said coating comprises:
Shield the screen 7 of said cable core 9;
Coat the outer belting layer 5 of said screen 7;
Coat the oversheath 8 of said outer belting layer 5;
And
Be arranged on the ground plane 4 between said cable core 9 and the said 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 is configured to ground plane 4: by the oblique wrapped said cable core 9 of bundle strand copper wire of stranded copper wire bundle strand, its lay of lapping is 18～28 times of said 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, thus the communication security of support equipment.
Like 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 said cable wire 101; Wherein said messenger wire overcoat 102 is structure as a whole with said oversheath 8, thereby realizes being connected of oversheath 8 of messenger wire overcoat 102 and power cable.
In addition, messenger wire 10 is parallel to said cable core 9, and said messenger wire overcoat 102 part that is said oversheaths 8.
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 of entering 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 explain as reinforced layer, so that increase the intensity of cable.
