Description

A kind of optoelectronic composite cable

Technical field

The utility model is related to optical fibre communication cable field, specially a kind of optoelectronic composite cable.

Background technology

With the high speed development on China's transmission cable road, the transmission line capability of newly-built circuit is being continuously increased, transmission cable road is being used The performance requirement more and more higher of wire.Where a lot of laying-outs, simultaneous transmission electric power and optical signal is generally required, as The optical cable of optical signal transmission and the cable as power transmission are typically laid respectively, and this not only brings inconvenience to construction, Increased use and construction cost.

But existing optoelectronic composite cable structure is not reasonable at present, easily rolls in the transport of composite rope and laid processes Disconnected, and combination property is bad, causes service life shorter, increases use cost.

Utility model content

The purpose of this utility model is to provide a kind of optoelectronic composite cable, with solve in above-mentioned background technology propose ask Topic.

For achieving the above object, the utility model provides following technical scheme：A kind of optoelectronic composite cable, including cable core and around Wrap the restrictive coating outside the cable core, the cable core includes optical fiber, reinforcement and at least one insulated wire cores, the optical fiber by Loose tube is coated, and is provided with water blocking yarn between the optical fiber and the Loose tube, and the Loose tube is equal with the insulated wire cores Stranded around the reinforcement, the inner insulating layer that includes to be extruded outside conductor and the conductor successively per insulated wire cores described in root, interior screen Layer is covered, the restrictive coating includes aramid fiber layer, external insulation layer, inner restrictive coating, armor and external sheath layer, institute from the inside to the outside successively State between aramid fiber layer and the reinforcement, the insulated wire cores and the Loose tube and gasket for packing is provided with, the inner restrictive coating Tear rope is provided between the external insulation layer.

Preferably, the reinforcement is steel wire.

Preferably, the internal shield is the wire sheathing that tin plating soft copper band is worked out.

Preferably, the inner insulating layer and the external insulation layer are made by pvc material.

Preferably, the inner restrictive coating is made up of crosslinked polyolefin materials, and the external sheath layer is made up of polythene material.

Preferably, the armor is made up of steel band or aluminium strip.

Compared with prior art, the beneficial effects of the utility model are：The optoelectronic composite cable is rational in infrastructure, by wherein The heart arranges reinforcement, and makes insulated wire cores and Loose tube all stranded in reinforcement, so as to enhance the bending resistance of the optoelectronic composite cable Qu Xingneng, also, due to being provided with internal shield, make shield effectiveness between many insulated wire cores more preferably, improve anti-interference energy Power, in addition, the optoelectronic composite cable also has preferably block water and fire resistance so that the life-span of the optoelectronic composite cable is prolonged Long, so as to reduce use cost.
