By using above-mentioned technical proposal, optical fiber and some transmission of electricity cores become the structure of bulk properties by cable, and pass through Barrier layer, inner sheath, shielded layer and oversheath, allow endothecium structure than more complete, the signal by shielded layer by cable entirety It is not interfered, in addition, by the steel wire worn on inner sheath and oversheath, makes the construction of cable harder, so as to is wearing During pipeline, its hard structure can be cleared up obstruction, facilitate the use of cable.
The utility model is further arranged to:The oversheath is provided with two layers, the steel wire be placed in two layers oversheath it Between.
By using above-mentioned technical proposal, the setting of two layers of oversheath allows steel wire in process of production, can facilitate its peace Put, its will not be allowed exposed in appearance.
The utility model is further arranged to:Metal coating is scribbled on the barrier layer inner wall.
By using above-mentioned technical proposal, the setting of metal coating can allow barrier layer to have certain shielding character, from And the signal of internal layer is allowed to further enhance antijamming capability.
The utility model is further arranged to:Nylon jacket is enclosed with the transmission of electricity core, gold is provided with the nylon jacket Belong to coating.
By using above-mentioned technical proposal, nylon jacket can allow power transmission line to be protected, and pass through the gold in nylon jacket Belong to coating, it is allowed with shielding properties, so that optical fiber and All other routes will not be interfered with each other for it.
The utility model is further arranged to:The optical fiber is enclosed with protective case in appearance, is provided with the protective case Metal coating.
By using above-mentioned technical proposal, protective case can protect optical fiber, and metal coating on it can Shielded, anti-stop signal is interfered.
The utility model is further arranged to:The internal layer is filled with polyethylene foam-material.
By using above-mentioned technical proposal, polyethylene foam-material has light, insulation, moisture-proof, abrasion-proof, corrosion-resistant etc. It is a series of superior to use characteristic.Weight so as to allow cable to a certain extent is lighter, meanwhile, allow its resistance to carry It is high.
The utility model is further arranged to:The inner sheath is formed using neoprene or polythene material.
By using above-mentioned technical proposal, neoprene and polythene material are respectively provided with excellent insulation performance, and With excellent anti-flammability, and then improve the comprehensive performance of cable.
The utility model is further arranged to:The oversheath is formed using pvc material.
By using above-mentioned technical proposal, polythene material has excellent insulation performance, and can be fire-retardant, so as to carry The high fire resistance of cable.
In conclusion the utility model has the advantages that:By the setting of steel wire, make the structure of whole cable strong Degree is higher, and by the use of fire proofing, allows whole cable to have excellent fire resistance, in addition, passing through polyethylene The setting of expanded material, allows the weight of cable to be mitigated.

In figure:1st, internal layer;11st, optical fiber;12nd, protective case;13rd, transmission of electricity core;14th, nylon jacket;2nd, barrier layer;3rd, inner sheath; 4th, shielded layer;5th, oversheath;6th, steel wire;7th, metal coating.
Embodiment
The utility model is described in further detail below in conjunction with attached drawing.
A kind of composite cable, as shown in Figure 1, the internal layer 1 formed including optical fiber 11 and some transmission of electricity cores 13, on internal layer 1 Barrier layer 2, inner sheath 3, shielded layer 4 and oversheath 5 are enclosed with successively, and the conductor of internal layer 1 is protected.Wherein, shield Layer 4 is staggered to form using metallic conduction silk.Some steel wires 6, steel wire 6 one are equipped with inner sheath 3 and oversheath 5 As be evenly arranged in the surrounding of internal layer 1, improve the structural strength of cable, make its hardness higher.So that in the construction process, When being passed through pipeline, directly the obstruction in pipeline can be cleared up, in the situation for the cleaning that obstruction is relatively difficult to Under, can also there is certain elastic force, obstruction can be crossed and pass through pipeline by the hardness of itself.
As shown in Figure 1, oversheath 5 is provided with two layers, steel wire 6 is placed between two layers of oversheath 5.Two layers oversheath 5 Setting allows steel wire 6 to facilitate its placement in process of production, can first produce a Rotating fields, is then placing steel wire 6, Another Rotating fields are produced, so that its will not be allowed exposed in appearance.Connection ring can be set between steel wire 6 and steel wire 6, pass through company Connecing ring, not only only inner sheath 3 or oversheath 5 provide by existing bonding strength between steel wire 6, can also be carried by connection ring For so as to increase its structural strength.
As shown in Figure 1, scribble metal coating 7 on 2 inner wall of barrier layer;The setting of metal coating 7 can allow barrier layer 2 to have There is certain shielding character, so as to allow the signal of internal layer 1 to further enhance antijamming capability.Meanwhile wrapped up on transmission of electricity core 13 There is nylon jacket 14, nylon jacket 14 can allow power transmission line to be protected, and metal coating 7 is provided with nylon jacket 14, passes through nylon jacket Metal coating 7 on 14, allows it with shielding properties, so that optical fiber 11 and All other routes will not be interfered with each other for it.Light Fibre 11 is also enclosed with protective case 12 in appearance, and protective case 12 can protect optical fiber 11, and gold is provided with protective case 12 Belong to coating 7, metal coating 7 can be shielded, and prevent 11 signal of optical fiber to be interfered.Metal coating 7 generally uses metallic copper Or the liquid of aluminium is coated.
