Abstract
The invention discloses a photoelectric composite cable preventing a wall from cracking. The electric cable comprises twisted electric-cable insulating wire cores. The electric-cable insulating wire cores comprise conductors and electric-cable insulating layers wrapping the conductors. Optical cable cores and filler are arranged between gaps of the electric-cable insulating wire cores in a twisted mode. The optical cable cores comprise optical fiber units, loose tubes wrapping the optical fiber units, reinforcing pieces distributed on the periphery of the loose tubes and protection sleeve layers wrapping the outmost layer. The electric-cable insulating wire cores are wrapped with insulating tape, a metal outer protection layer is arranged outside the insulating tape, a galvanized steel strip armor layer is arranged outside the metal outer protection layer, and fireproof heat isolation tape is arranged between the insulating tape and the metal outer protection layer and is fireproof mica tape. The photoelectric composite cable has the advantages of preventing the wall from cracking, being reasonable in design, simple in structure and convenient to construct, improving working efficiency, reducing construction cost and facilitating popularization.

And the photoelectric compound cable of prior art is when indoor laying, because the bending resistance of composite cable is poor, construction procedure is complicated, and then reduced operating efficiency, increased construction cost, not outer composite cable was laid after a period of time in body of wall, owing to producing larger stress in the flexible covering of composite cable, and then metope cracking, bulge after having caused composite cable to lay in the short time metope to restore, the deficiency such as chap, the outward appearance of construction body of wall has been caused to impact.
Yet for the deficiencies in the prior art, developer is necessary to develop and a kind ofly prevents that body of wall from chapping, reasonable in design, simple in structure, easy construction, increases work efficiency, reduces construction cost, is convenient to the photoelectric compound cable promoted.
Summary of the invention
What the present invention will solve prevents that body of wall from chapping, reasonable in design, simple in structure, easy construction, increases work efficiency, reduces construction cost, is convenient to the photoelectric compound cable promoted for prior art deficiency a kind of.
For solving above technical problem, the present invention realizes by the following technical solutions: a kind of photoelectric compound cable that prevents that body of wall from chapping, comprise stranded cable insulation core mutually, described cable insulation core comprises conductor and is coated on the cable insulation in conductor outside;
Stranded between described cable insulation core gap have Cable Core and a filler; Described Cable Core comprises fiber unit, is coated on the loose sleeve pipe in fiber unit outside, is distributed in the reinforcement of loose sleeve pipe surrounding and is coated on outermost restrictive coating;
Described cable insulation core is coated with type insulating wrapping strip, described type insulating wrapping strip outside is provided with metal outer jacket, described metal outer jacket is galvanized steel strip armour, in the middle of described type insulating wrapping strip and metal outer jacket, is provided with refractory heat-insulating band, and described refractory heat-insulating band is fire-resistant isinglass belt.
In a preferred embodiment of the invention, described fiber unit is optical fiber, fiber bundle or fibre ribbon.
In a preferred embodiment of the invention, described conductor is copper conductor or aluminium conductor.
In a preferred embodiment of the invention, described cable insulation and type insulating wrapping strip are made by second the third insulating material.
