Background technology
At present, existing cable is constantly present some big and small deficiencies, such as people in order that certain functional effect
More protrude, and some materials are abused, cause that the sectional area of cable is very big and cable is heavier in itself, using also very
It is inconvenient.
The content of the invention
The invention aims to solve shortcoming present in prior art, and a kind of small bore electric power proposed is electric
Cable.
To achieve these goals, present invention employs following technical scheme：
A kind of small bore power cable, it includes cable core, insulating barrier, screen layer, gasket for packing, resistance to compression armor, fire protection flame retarding layer
And corrosion-resistant coating；The insulating barrier includes the first insulating barrier and the second insulating barrier；The screen layer includes internal shield and external screen
Cover layer；The cable core includes two identical conductors, two insulating barriers of identical first and an internal shield；Two identicals
Two insulating barriers of identical first are extruded with outside the conductor respectively；Described in two identicals one layer is extruded with outside the first insulating barrier
Internal shield；One layer of external shielding layer is extruded with outside the internal shield；One layer of resistance to compression armor is extruded with outside the external shielding layer；
One layer of fire protection flame retarding layer is extruded with outside the resistance to compression armor；The fire protection flame retarding layer is outer to be extruded with one layer of corrosion-resistant coating.
A kind of above-mentioned small bore power cable, be extruded with the external shielding layer and outside the cable core two it is identical
Gasket for packing.
Above-mentioned a kind of small bore power cable, outside gasket for packing described in two identicals and cable core and in the external shield
Two insulating barriers of identical second are extruded with layer.
A kind of above-mentioned small bore power cable, the external shielding layer, resistance to compression armor, fire protection flame retarding layer and corrosion-resistant coating
Cross section assume diamond in shape structure.
A kind of above-mentioned small bore power cable, the cable core, conductor, the first insulating barrier, internal shield, gasket for packing and
The oval structure in cross section of two insulating barriers.
Compared with prior art, the beneficial effects of the invention are as follows：
A kind of main body section of small bore power cable of the present invention is rendered as diamond structure, and this not only causes the structure of cable more
It is firm, and maximum secting area also very little, thus reach it is lightweight, using convenient transportation and other effects；The gasket for packing of setting, first
The advantages of insulating barrier, the second insulating barrier, internal shield and external shielding layer are conducive to improving the stability of cable transmission signal.
Brief description of the drawings
Fig. 1 is lateral cross section structural representation of the invention；
In figure：1st, cable core；2nd, conductor；3rd, the first insulating barrier；4th, internal shield；5th, gasket for packing；6th, the second insulating barrier；7th, external shield
Layer；8th, resistance to compression armor；9th, fire protection flame retarding layer；10th, corrosion-resistant coating.
Embodiment
Such as Fig. 1, a kind of small bore power cable, it includes cable core 1, insulating barrier, screen layer, gasket for packing 5, resistance to compression armor
