Description
Technical field
The present invention relates to power Transmission technical field more particularly to a kind of carbon fibre materials wire and cables.
Background technique
Existing cable, generally using zinc-coated wire as core, outer layer is twisted circular aluminium alloy wire.This cable master
There are following several respects: one, due to outer layer be twisted be circular aluminium alloy wire, lead to the gap between line and line
Greatly, effective sectional area is small, and outer diameter is big, and occupied space is big in storage and transportational process.Two, shape is twisted by circular aluminium alloy wire
At superficies it is uneven, rough, be easy accumulation ice and snow or other weight bearing substances, increase the weight bearing of cable, anti-ice-snow
Ability is poor, is easy to bend and destroys cable.Three, the tensile strength of zinc-coated wire used is low, and weight is big, and span is smaller when erection, frame
If shaft tower quantity needed for cable is more, not only cost is big, wasting manpower and material resources, and land occupation resource is more.
Based on problem above, existing cable has been unable to satisfy the new demand of power construction fast development.
Summary of the invention
The purpose of the invention is to overcome the deficiencies of the prior art and provide a kind of carbon fibre materials wire and cable.
The present invention is achieved through the following technical solutions:
A kind of carbon fibre materials wire and cable, including the conductor sandwich layer formed by carbon fiber complex core, the conductor cores
Layer successively includes duralumin round wires twisted layer, carbon fiber clad, thermal insulation layer, limit sheath and oversheath from inside to outside；
The duralumin round wires twisted layer, carbon fiber clad and thermal insulation layer setting are in limit sheath；
The oversheath includes PET plastic twining package tape from inside to outside, and twining package tape is wrapped with woven wire cloth, metal
Mesh grid is wrapped with rubber protecting jacket；
Magnesia filler is equipped in gap between the limit sheath and oversheath.
Further, one end of the carbon fiber clad is provided with AC/DC convertor.
Further, the limit sheath is flexible plastic.
Further, the duralumin round wires twisted layer is that 3 bursts of duralumin round wires are twisted.
Further, the conductor sandwich layer includes a carbon fiber complex core.
Compared with prior art, the beneficial effects of the present invention are: utilizing the twisted conductor cores formed of carbon fiber complex core
Layer improves the tensile strength of overhead power transmission cable, and light-weight, it can be achieved that large span makes somebody a mere figurehead and improves current-carrying capacity, frame
Shaft tower quantity needed for empty power transmission cable is reduced, and greatly reduces the costs such as manpower and material resources, and land resource is few；Limit sheath
Setting strengthen the stability between cable, avoid the displacement of cable；And the woven wire cloth on oversheath is greatly
The strong ageing resistance of cable, to extend service life.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
In figure: 1, duralumin round wires twisted layer；2, carbon fiber clad；3, thermal insulation layer；4, sheath is limited；5, outer shield
Set.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
A kind of carbon fibre materials wire and cable shown in FIG. 1 is please referred to, including the conductor cores formed by carbon fiber complex core
Layer, the conductor sandwich layer successively include from inside to outside duralumin round wires twisted layer 1, carbon fiber clad 2, thermal insulation layer 3,
Limit sheath 4 and oversheath 5；
The duralumin round wires twisted layer 1, carbon fiber clad 2 and the setting of thermal insulation layer 3 are in limit sheath 4；Reinforce
Stability between cable, avoids the displacement of cable.
The oversheath 5 includes PET plastic twining package tape from inside to outside, and twining package tape is wrapped with woven wire cloth, gold
Belong to mesh grid and is wrapped with rubber protecting jacket；Woven wire cloth has greatly reinforced the ageing resistance of cable, extends and uses the longevity
Life.
Magnesia filler is equipped in gap between the limit sheath 4 and oversheath 5.
Wherein, one end of the carbon fiber clad 2 is provided with AC/DC convertor；It can also connect on AC/DC convertor
Connect earth leakage protective device and temperature controller.
Wherein, the limit sheath 4 is flexible plastic, the duralumin round wires twisted layer 1 be 3 bursts of duralumin round wires it is twisted and
At the conductor sandwich layer includes a carbon fiber complex core.
Compared with traditional similar product, carbon fiber composite cable of the invention can meet big section high pressure, extra-high crimping
The construction on road reduces the loss of electric power in the transmission, improves power transmission efficiency.
Carbon fiber composite cable of the invention is using the twisted conductor sandwich layer formed of carbon fiber complex core, to improve frame
The tensile strength of empty power transmission cable, and it is light-weight, it can be achieved that large span makes somebody a mere figurehead and improves current-carrying capacity, overhead power transmission cable institute
The shaft tower quantity needed is reduced, and greatly reduces the costs such as manpower and material resources, and land resource is few；The setting of limit sheath strengthens
Stability between cable avoids the displacement of cable；And the woven wire cloth on oversheath has greatly reinforced the anti-of cable
Aging ability, to extend service life.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
