Accompanying drawing explanation

Below in conjunction with accompanying drawing, the utility model is described in further detail:

Fig. 1 is the utility model the first example structure schematic diagram;

Fig. 2 is the utility model the second example structure schematic diagram.

Embodiment

With reference to Fig. 1, Fig. 2, the utility model provides a kind of stranded carbon fiber optical fiber composite overhead wire, comprises the conductive layer 2 of core 1 and coated core 1, and core 1 comprises carbon fiber strengthening core 11 and optical fiber combination core 12.

In this stranded carbon fiber optical fiber composite overhead wire, carbon fiber strengthening core 11 and optical fiber combination core 12 are coated on to conductive layer 2 inside in the lump, by by carbon fiber composite conductor technology and optical fiber technology perfect adaptation, make the utlity model has aerial condutor and the dual-use function of communicating by letter, have carbon fiber composite conductor comprises lightweight simultaneously, low orphan is hung down, resistance to chemical attack, long service life, nonmagnetic, high temperature resistant, all advantages such as overload capacity is strong, thereby greatly limit meets various different environments for use, the particularly electric power of large spanning overhead line and communications requirement.

As the utility model preferred embodiment, optical fiber combination core 12 comprises metal tube 121 and is located at the some fiber bundles 122 in metal tube 121.

As the utility model preferred embodiment, metal tube 121 is stainless steel tube.The impact that the setting of metal tube 121 avoids external signal to transmit for fiber-optic signal.

As the utility model preferred embodiment, carbon fiber strengthening core 11 is for being evenly stranded in the carbon fiber bundle in optical fiber combination core 12 outsides.Carbon fiber bundle is evenly stranded in the outside of optical fiber combination core 12, avoid outer conductor lines 21 stranded when the conductive layer 2 for the destruction of optical fiber combination core 12, play a protective role.

As the utility model preferred embodiment, conductive layer 2 is by stranded the forming of some conductor lines 21.

As the utility model preferred embodiment, conductor lines 21 is heat-resistant aluminum alloy wire or superalloy conductor or aldray wire or fine aluminium wire or high-purity aluminium wire.

As the utility model preferred embodiment, the cross section of conductor lines 21 is circular or trapezoidal.Cross section is in the situation of circular conductor lines same cross-sectional area, the size of conductive layer 2 is thicker, windage is larger, but heat radiation better, contrary cross section is that trapezoidal conductor lines 21 can effectively reduce windage, but it is poor to dispel the heat, for the conductor lines 21 of two kinds of section forms, can specifically select according to actual conditions.
