Abstract
The utility model relates to a lightning protective cable, comprising an oversheath, an insulating layer and a cable core, wherein the insulating layer is arranged in the oversheath, the cable core is mounted in the insulating layer and comprises a plurality of independent cable cores successively coated with a shielding layer and an insulating layer I. A fireproof layer is filled between the cable core and the insulating layer. A grounding layer is disposed between the insulating layer and the oversheath and formed by a plurality of copper wires lapping outside of the insulating layer in an inclined manner. The advantages are that the lightning protective cable provided by the utility model has a simple cross-section structure, the grounding layer disposed between the insulating layer and the oversheath can effectively conduct an instantaneous high voltage, thereby preventing thunderbolt form damaging communication devices.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of lightning protected cable.
Background technology
Mostly addressing is spaciousness, highland or mountain area based on base station construction, with a varied topography and work under bad environment, and the equipment of base station suffers the infringement of thunder and lightning weather easily, in case cable is struck by lightning, will cause the heavy losses of communication equipment.
Summary of the invention
The purpose of the utility model is exactly the weak point in the background technology, and a kind of lightning protected cable is provided.
For achieving the above object, the utility model adopts following technical scheme: a kind of lightning protected cable comprises oversheath, insulating barrier and cable core; Be provided with insulating barrier in the oversheath; Be provided with cable core in the insulating barrier, cable core comprises some independent cable cores that are coated with screen, insulating barrier I successively, is filled with flame retardant coating between cable core and the insulating barrier; Be equipped with ground plane between insulating barrier and the oversheath, this ground plane wrappedly forms outside insulating barrier by stranded copper wire is oblique.
A kind of optimization for the utility model; Said independent copper core is for to be made up of central copper core, middle copper sandwich layer, outer copper sandwich layer; The central copper core is single copper core, and the middle copper sandwich layer is that six roots of sensation copper core and enclosing overlays on outside the central copper core, and outer copper sandwich layer is 12 copper cores and and encloses and overlay on outside the middle copper sandwich layer.
The utility model is compared with background technology, and it is simple to have a cross section structure, and the ground plane that is provided with between flame retardant coating and the oversheath can effectively conduct instantaneous high pressure, avoids thunder and lightning that communication equipment is caused damage.
Description of drawings
Fig. 1 is the cross section structure sketch map of lightning protected cable.
Fig. 2 is the cross section structure sketch map of cable core.
Embodiment
Embodiment 1: with reference to Fig. 1 and 2.A kind of lightning protected cable; Comprise oversheath 1, insulating barrier 3 and cable core, be provided with insulating barrier 3 in the oversheath 1, be provided with cable core in the insulating barrier 3; Cable core comprises some independent cable cores 53 that are coated with screen 52, insulating barrier I 51 successively; Be filled with flame retardant coating 4 between cable core and the insulating barrier 3, be equipped with ground plane 2 between insulating barrier 3 and the oversheath 1, this ground plane 2 wrappedly forms outside insulating barrier 3 by stranded copper wire is oblique.Said independent copper core 53 is for to be made up of central copper core 53a, middle copper sandwich layer 53b, outer copper sandwich layer 53c; Central copper core 5a is single copper core; Middle copper sandwich layer 5b is that six roots of sensation copper core and enclosing overlays on outside the central copper core 5a, and outer copper sandwich layer 5c is 12 copper cores and and encloses and overlay on outside the middle copper sandwich layer 5b.
Combined accompanying drawing that the embodiment of the utility model has been carried out exemplary description above, obviously the utility model is not limited thereto, and the various remodeling that in the utility model scope, carry out all belong in the protection range of the utility model.
