Abstract
A wind energy composite cable transmitting audio, video and data comprises a cable core and a wrapping tape and an outer sheath sleeved outside the cable core, and is characterized in that the cable core comprises a communication wire, a coaxial radio frequency wire, a control wire and a plastic core; the communication wire, the coaxial radio frequency wire and the control wire are in spaced arrangement in circumference mode, and the plastic core is arranged in the center of the circumference; the polyester film wrapping tape is wrapped outside the cable core, and the cold-resistant butyronitrile polyvinyl chloride (PVC) elastomer outer sheath is extruded outside the wrapping tape. The cable achieves integral transmission of the audio, the video and data signals, the cable is laid in one-shot mode, multiple functions are achieved, and at the same time the cable has good low temperature resistance, flexibility, torsion resistance and long service life.
Description
Technical field
The utility model relates to a kind of integrated data cable, specifically a kind of wind energy audio frequency, video, transfer of data composite cable that is applied to the wind power plant use.
Background technology
In recent years, China's wind-powered electricity generation industry fast development, and the special-purpose wind energy series cable of China's wind power generation still is in the starting stage, the cable that is used for tower tube internal transmission signal does not at present have unified standard or standard.Because the geographical position of wind power generation is remote, environment is abominable, and is relatively stricter to the instructions for use of blower fan and cable.The blade rotation of blower fan becomes electric energy through generator with mechanical energy, through power cable electric energy is sent to high voltage substation in tower tube inside; These a series of wind power generation processes all need real-time signals such as audio frequency, video, data to be transferred to Access Network control centre, and this just need increase connection in the tower tube, video line; Control line all is to transmit respectively with cable through the network that separates and be used for transmission of audio, video, data-signal in the present most blower fan tower barrel, and three kinds of cables all need lay separately; Trouble is installed; Construction cost is high, because the performance and the material therefor of signal cable are limit, can't realize low temperature resistant distortion performance simultaneously; The signal cable not warp resistance that under low temperature condition, ftractures has had a strong impact on the monitoring of fan operation.
The utility model content
The utility model is the deficiency of bringing in order to overcome existing used for wind power generation cable sound intermediate frequency, video, separately setting up of data-signal; A kind of integrated data cable that can realize audio frequency, video, the integrated transmission of data-signal is provided, and this cable has been realized good warp resistance property simultaneously.
Realize that the technical scheme that the foregoing invention purpose adopts is: a kind of wind energy audio frequency, video, transfer of data composite cable; Comprise band and oversheath that cable core is outside with being sleeved on core; It is characterized in that described cable core comprises connection, coaxial radio-frequency line, control line and glue core; Described connection, coaxial radio-frequency line and control line circle spacing arrange, and the glue core is arranged on the centre of circumference; The outer wrapped polyester film band of cable core, band extrudes cold-resistant butyronitrile PVC elastomer oversheath outward.
The utility model cable has been realized audio frequency, video, the integrated transmission of data-signal, and the cable once-paving is realized multiple function, and this cable has good low-temperature resistance property, flexibility, the anti-property reversed, long service life simultaneously.
Description of drawings
Fig. 1 is the section structure sketch map of the utility model.
Among the figure: connection 1, coaxial radio-frequency line 2, glue core 3, control line 4, band 5, oversheath 6.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Referring to accompanying drawing 1, this integrated data cable disclosed in the utility model comprises band and the oversheath that cable core is outside with being sleeved on core, and cable core comprises connection 1, coaxial radio-frequency line 2, control line 4 and glue core 3.Connection 1, coaxial radio- frequency line 2 and 4 circle spacings of control line arrange, and glue core 3 is arranged on the centre of circumference.The outer wrapped polyester film band 5 of cable core, the band 5 outer butyronitrile PVC elastomer oversheaths 6 that resist cold that extrude.
As preferred version: the connection 1 in the cable core, coaxial radio-frequency line 2 and control line 4, the mode that adds PVC glue core 3 concentric strandings through the heart therein is made into circular cable core.The coaxial radio-frequency line adopts ASYV-75-5 model coaxial radio frequency cable, and its inner wire is by seven copper wire stranded compositions, and polyethylene is adopted in insulation, the outer copper wire braid shielded that insulate, and vertical simultaneously alclad plastic composite strip extrudes low temperature resistant PVC elastic body jacket outside copper wire weaves.Connection is 5 types of cables of the non-shield type of pair twist, the outer cohering ethene insulation of copper conductor, and it is right that the insulated wire cores of different colours is twisted respectively, and cable is formed in the unit of four pair twists, extrudes the low temperature resistant PVC elastic body jacket of one deck at last.Control line is that model is the four-core flexible cable of RVV, and it is elastic body insulated that the soft copper conductor squeezes cold-resistant PVC outward, 4 insulated core strandings, and wrapped polyester film band during stranding, polyester film band extrude the low temperature resistant butyronitrile PVC of one deck elastic body jacket outward.
