Description

Photoelectric compound cable

Technical field

This utility model is related to field of cable technology, more particularly, to a kind of composite cable integrating photoelectricity transmission.

Background technology

It is surging forward with telecommunications, in communication network service, telephone service is in stable growth trend, and data industry Business is exponentially increased situation, and the multimedia of voice, data and image etc. is both needed to transmit, so needing bigger network capacity and more Wide bandwidth.

Utility model content

This utility model is directed to the problems referred to above of the prior art, provides a kind of photoelectric compound cable, and its structure is simple, tool There are low cigarette, Halogen, fire-retardant, waterproof, cold resistant property.

The technical scheme that this utility model is adopted is as follows：

Photoelectric compound cable, including the cable core being made by twisting by two armored optical cables and power cable, described power cable Insulating barrier including conductor and outside extruding in conductor；Described cable core gap is packed layer, wrapped poly- successively outside described cable core Ester band, screen layer, aluminium-plastic tape, sheath and outer jacket；

The further technical scheme of this practicality is as follows：

Further, conductor is made by twisting using tin plating soft copper silk；

The first step, insulating barrier is pvc material, and insulation thickness is 0.9mm, and outer insulation diameter is 5.3mm；

Second step, packed layer is polypropylene material；

3rd step, screen layer adopts tinned copper wire braiding structure；

4th step, sheath adopts polythene material；

5th step, outer jacket adopts low smoke halogen-free flame-retardant polyolefin.

The utility model has the advantage of：

Communication and the function that transmits electric power are integrated in one, using new structure and material, strengthen cable various aspects of performance, There is provided multiple transmission technologys it is ensured that cable normally runs under low temperature, burning, Soaking environment, there is low cigarette, Halogen, fire-retardant, anti- Water, cold resistant property.

Brief description

Fig. 1 is this utility model structural representation.

Specific embodiment

Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described.

As shown in figure 1, this utility model includes the cable core being made by twisting by two armored optical cables 9 and power cable, described Power cable includes conductor 1 and the insulating barrier 2 extruding outside in conductor 1, and conductor 1 is made by twisting using tin plating soft copper silk, and it is several What is generally circular in shape, and many stranded conductors should press, and circle presses copper conductor many advantages compared with sector conductor：Wrapped So that mica tape is tightly combined with conductor during mica tape, be conducive to electric fields uniform to be distributed, strengthen the electrical insulation properties of cable, simultaneously The consumption of mica tape, reduces cost can be saved, insulating barrier 2 is pvc material, insulation thickness is 0.9mm, outer insulation diameter For 5.3mm, in optical fiber covered wire, there is minimum steel belt protection optical fiber, ensure the making of optical fiber in stranding or in particular cases Use characteristic；

Described cable core gap is packed layer 3, wrapped polyester belt 4, screen layer 5, aluminium-plastic tape successively outside described cable core 6th, sheath 7 and outer jacket 8；Preferably, packed layer 3 is made using polypropylene material, and it can make cable core more complete；Polyester Play the effect tightening cable core with 4, screen layer 5 adopts tinned copper wire braiding structure, the electric current passing through in cable is larger, electric current week Enclose and can produce magnetic field, do not affect other elements, screen layer can this electromagnetic-field-shielded in cable；May also operate as one If fixed ground protection effect core occurs breakage, the electric current leaking can flow into grounded screen along screen layer, using plating Stannum, prevents copper wire from aoxidizing, affects screen layer performance；Aluminium-plastic tape 6 and sheath 7 composition waterproof layer, sheath 7 adopts poly- second Alkene material is made, and, using cold-resistant low smoke halogen-free flame-retardant polyolefin, its relative density is little, chemical proofing, resistance to water for outer jacket 8 Good, have good mechanical strength, electrical insulation capability.

Above description is to explanation of the present utility model, is not the restriction to utility model, and this utility model is limited Scope, referring to claim, within protection domain of the present utility model, can make any type of modification.
