Description
Technical field
The present invention relates to field of cables, specifically a kind of wind energy tension fiber composite power cable.
Background technology
National electric wire Quality Supervision and Inspection Center formally implements low-temperature wind-energy power cable in May, 2009
Technical specification, the specification is in physical dimension, the material for using and performance, electric pressure, use environment temperature, use occasion, examination
It has been described in detail in proved recipe method.Low-temperature wind-energy power cable is very different in product quality before this, it is substantial amounts of not
Qualified or severe product floods market, and brings economic loss to user, seriously threaten electrical control equipment, power system it is normal
Operation.
As country is continuously increased to the demand of regenerative resource, therefore as the low temperature of wind power plant auxiliary products
Wind energy power cable, becoming has the cable new varieties of huge market potential, develops and invests market.Low temperature wind energy electric power electricity
Stranded mode of the conductor of cable using multiply layering, the pitch range of stranded conductor：21-25 times of strand, internal layer：17-20 times, it is outer
Layer：11-14 times, stranding takes different stranding lay ratios, mobile occasion by different code names：Lay ratio is not more than laying up diameter
14 times；Non-moving occasion：Lay ratio is not more than 18 times of laying up diameter.The stranded pliability of conductor is good, and torsional resistance is good.Cause
This, is widely used in connection or the connection for the inside and outside non-moving power supply of tower of wind power generation machine rotor etc..Low temperature wind energy electric power electricity
Cable solves the hidden danger of equipment safety operation, have updated environmental benefit, brings economic benefit.Existing low-temperature wind-energy power cable
Advantage be：Warp resistance.Shortcoming is：Long-term reciprocal positive anti-twist, Jing stranded conductor and conduction on wind power plant
The core life-span is not very long, and cable is easily deformed, and causes easily to be twisted off.And the reason for these defects, it is because stranded conductor
Pitch is sparse, stranded conductor is not that very closely, the pliability of conductor is general, pre- torsion during no positive and negative back twist.
With the substantial increase of China's supertension and the high voltage power cable amount of laying, the operation safety of power cable and quality
Monitoring is more and more important, needs using distribution type fiber-optic measuring system（DTS）Enter trip temperature, transmission load monitor in real time, to super
High pressure and high voltage power cable realize that internal or external extraordinary temperature measuring optical cable becomes optical fiber composite high-voltage cable, i.e., so-called " intelligence
Energy cable ".Meanwhile, " integration of three networks " has been included the Pilot project construction of intelligent grid for Utilities Electric Co., and national grid is pushed in the whole nation
Power optical fiber is registered one's residence, it is desirable to realize electrical network end electric power and communication " integration " power optical fiber to family photoelectric compound cable.
The content of the invention
The present invention is in order to solve problems of the prior art, there is provided a kind of current-carrying capacity is big, block-water performance is good, corrosion resistant
The wind energy tension fiber composite power cable of erosion, resistance to oxidation, big mechanical strength, protection against the tide and good airproof performance.
A kind of wind energy tension fiber composite power cable of the present invention, including cable core, the cable core is by one, center light
Fan-shaped insulated wire cores are stranded forms for fine unit and be centered around outside fiber unit four；In fiber unit and four fan-shaped insulation
The gap filling water blocking yarn of core twisted synthesizing cable；Metal anti-stretching pipe, and the coating drip on metal anti-stretching pipe are externally provided with cable core
Green grass or young crops, then compact winding thicker wire armor, extrude medium density polyethylene separation sleeve in thicker wire armor, finally in cable outermost
Layer extrudes medium density polyethylene oversheath.
Further improve, the fan-shaped insulated wire cores press stranded sector by pressing stranded fan-shaped copper conductor and be extruded in
Crosslinked polyetylene insulated layer outside copper conductor is constituted.
Further improve, described fiber unit is made up of optical fiber and the silk thread beam being extruded in outside optical fiber.
Further improve, described metal anti-stretching pipe is thin copper belt Jing longitudinal tubings, welds, rolls the wrinkle copper for twisting
Pipe.
Compared with prior art, the beneficial effects of the present invention is：
1st, the present invention has preferably ensured air-tightness and cable bend using argon arc welding corrugated copper tube as radial direction tensile structure
Performance, using resistance thicker wire armor as longitudinal tensile structure, the double shield tensile property of cable.
2nd, thicker wire, argon arc welding corrugated copper tube can also play preferable drawing-resistant function, collide with stronger external force
Function.
3rd, the present invention is provided with fiber unit, can enter trip temperature, transmission load monitor in real time to power cable, can be used in
" integration of three networks "；Silk thread beam surrounds the optical fiber for directly dragging, and optical fiber will not be pulled off, and silk thread beam has been also carried out effective protection to optical fiber,
Will not be extruded when processing, laying, particularly when cable runs, certainly will will generate heat and expand, it is ensured that have space to hold
Nano fiber, inside of the elastic material again to expanding provide the space of buffering, it is ensured that optical fiber will not be damaged, and normally can transport
OK.
