Description
Technical field
The utility model belongs to power cable field, specifically a kind of cold-resistant distortion flexible cable used for wind power generation.
Background technique
In the 21st century, China rapid economic development, industrialization, Development of China's Urbanization are accelerated, energy demand rapid growth, energy
Source imbalance between supply and demand becomes increasingly conspicuous.Increase the diversification supply of the energy, ensure that energy security has become the important of socio-economic development
Task, development and utilization renewable energy become the important component of national energy development strategy.As one of renewable energy
Wind-power electricity generation, since resource potential tool is big, environmental pollution is low, can continuous utilization, and generation technology has been mature on the whole, economical
Property has been approached conventional energy resource, is paid much attention in China.
With the fast development of wind power industry, the demand to cable for wind power generation is expedited the emergence of, wherein warp resistance electricity
Power cable is the maximum cable of usage amount.Due to the bad environments of wind power plant, blower service life is longer, and some product
Kind cable need to also constantly be rotated with blower, very high to the performance requirement of cable.These cables relied primarily on import in the past, and price is high
It is expensive.In recent years, domestic many manufacturing enterprises are researched and developed, and have produced low temperature resistant, UV resistant, oil resistant, anti-warp resistance
Cable for wind power generation, but these cables are 1.8/3kV and following voltage class cable mostly, for voltage rating 12/20kV,
Warp resistance wind energy cable is pressed in 18/30kV, 20/35kV, it is main still to rely on import.It can research and develop by testing and being used for
The enterprise of practice is not much, and the middle pressure distortion-resistance wind power generation of existing research is with cable mainly with three-core structure, structure master
With reference to the structure of middle pressure rubber cable, that is, insulation system uses inner shield+insulation+external shield, and gold is woven with outside external shield
Belong to braiding layer, then more insulated electric conductor parallel connections is twisted into cable core, then be extruded with oversheath outside cable core.
The prior art has been primarily present two aspect problems:
1, the type cable needs are reversed for a long time, and cable is due to internal without reinforcing stable structure in the prior art
Because long-term torsion is easy to appear bulge phenomenon；
2, since such cable is from great, cable needs are for a long time used in 20 meters of difference in height in addition, in addition cable
It being used under the action of continuous twisting resistance, the meeting at cable connector is easy because accepting the joint fracture for concentrating and generating cable,
To influence to use.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of wind resistances by force, the wind-force of good heat preservation performance, self-heating
Generate electricity cold-resistant distortion flexible cable.
One kind cold-resistant distortion flexible cable used for wind power generation described in the utility model, including cable core, the cable core by
A plurality of insulated core is twisted；Heat-preservation cotton is filled in the gap of cable core, butyl glue layer is coated with outside cable core, in butyl rubber
Wrapped cold-proof inner sheath outside water layer weaves the non magnetic steel wire armor with metal structure that adds non-magnetic steel outside inner sheath,
Wrapped elastic cord breaker outside armor, is extruding polyurethane thermal pipe outside elastic cord breaker；The cold-proof inner sheath is by protecting
The mixture of set major ingredient and sheath auxiliary material is made.
It is further improved, the insulated wire cores are by reinforcement steel core, the aluminium alloy conductor being stranded in outside reinforcement steel core and squeeze
The insulating layer wrapped outside aluminium alloy conductor is constituted.
It is further improved, the elastic cord breaker, which includes that flexibility is interior, to be padded and pad outside flexible, pad and flexibility in the flexibility
Several air bags are provided between outer pad.
It is further improved, further includes fluorescence radiation colour band, axis of the fluorescence radiation colour band along the polyurethane thermal pipe
The setting of line direction.
The utility model has the beneficial effects that:
1, it is equipped in conductor and reinforces steel core, not only make the tensile strength of cable be greatly improved, but also flexible
Property it is good, there is good inoxidizability and flame retardant property, and elongation at break is smaller, is not susceptible to deform.
2, the improvement of the insulated wire cores structure of the utility model, so that insulated wire cores itself have cold-resistant, elastic property.
3, filling uses heat-preservation cotton, so that the internal insulation effect of cable is more preferable.
4, non-magnetic steel band metal armor layers structure type is added using non magnetic steel wire, to reach good pull resistance, resist
Interference, long service life and other effects.
5, one layer of butyl glue being coated with outside cable core, being then extruded with inner sheath, after vulcanizing, cable internal structure is just extremely
Stablize, is laying cable, length travel does not occur in drawing process；The conductor of cable is led by the way of being twisted in the same direction
Each layer is twisted according to a direction outside body, can enhance the twisting property of cable in this way, in twist process also more
Freely, an entirety is made so that cable various components inside is all combined together by the improvement of above three aspect,
While its resistance to twisting property obtains increasing, also there is a phenomenon where bulges.
6, core and cable are equipped with elastic cord breaker, can effectively buffer from extraneous pressure, protect well
Each layer of cable has been protected not by extraneous extruding, and there is Wind-Pressure Resistance ability, cable is normally worked.
7, core and cable are equipped with polyurethane thermal pipe, protect the cold resistance of cable so that cable have intensity it is high,
Impact resistance, the prestressing force of resistance to environmental aging split, be corrosion-resistant, is low temperature resistant, easy welding, easy construction, strictly seals ne-leakage, also has
There are the excellent characteristics such as bulk density is light, intensity is high, insulation, sound insulation, fire-retardant, cold-resistant, anti-corrosion, do not absorb water, simple and quick construction, in addition,
Polyurethane heat insulation material, adaptive temperature is+120 DEG C--196 DEG C, so that cable is in ice and snow weather because icing causes signal of communication
Transmission causes the economic loss that can not be saved.
8, fluorescence radiation colour band is arranged in the axis direction of the polyurethane thermal pipe, can be dark or insufficient light
It itself can shine under environment, make people that can intuitively see cable position clearly in daily production and living, convenient for effectively keeping away
Cable run is opened, in case damage cable, is also prevented from and is hurt by impaired cable, more to maintenance, repairing and the maintenance under dark surrounds
Equal related works provide convenience.
