Description
Technical field
The present invention relates to cable technology field, relate in particular to the super cold-resistant cable for wind power generation of a kind of radiation proof.
Background technology
At present, the special cable of China's wind power generation is still in the starting stage.Because the environment of wind power generation is severe, blower fan is longer service life, higher to the performance requirement of cable.The environmental quality of wind energy cable operation is long-term moving going in outdoor, vertical unsettled setting up, and frequent torsion (automatically going off course to wind), contact greasy dirt direct sunlight etc., ocean cable for wind power generation also will prevent the corrosion of seawater simultaneously.Due to the harshness of cable running environment and condition, the requirements such as so also very high to the requirement of cable for wind power generation, mechanical strength is high, low temperature resistant, radiation proof.
Summary of the invention
In order to solve the technical problem existing in background technology, the present invention proposes the super cold-resistant cable for wind power generation of a kind of radiation proof, it is simple in structure, shielding property is good, can under cold environment, use safety for a long time.
The super cold-resistant cable for wind power generation of a kind of radiation proof that the present invention proposes, comprises by multiple conductors; Each conductor comprises the wire that is positioned at middle part and semiconductive polyethylene layer, insulating barrier and the screen that is coated on successively wire outside, and insulating barrier adopts cold-resistant silicon rubber to make, and described screen adopts metal screen layer; By the parallel multiple conductors vertical cable that is set to, in the outside coated nonwoven layer of cable core, at the outside coated inner sheath of nonwoven layer, at the outside coated lubricating layer of inner sheath, at the outside coated oversheath of lubricating layer, described inner sheath and described oversheath all adopt cold-resistant silicon rubber to make.
Preferably, described wire adopts many stranded the forming of copper free wire.
Preferably, described conductor is symmetrical arranged in cable.
Preferably, described screen adopts copper strips to put up vertical packet form.
Preferably, described nonwoven layer is provided with Z-Correct bump mapping Z-correct.
Preferably, described lubricating layer adopts thin metal bisque.
In the present invention, insulating barrier, inner sheath and oversheath adopt cold-resistant silastic material to make, and strengthen cable service behaviour at low temperatures; Semiconductive polyethylene layer is set between wire and insulating barrier, prevents gap therebetween, and play the effect of internal shield, ensure wire equipotential and with insulating barrier good contact, avoid wire and surface of insulating layer generation partial discharge; There is the nonwoven layer of Z-Correct bump mapping Z-correct in conductor outer cladding, in the time of cable bend, make cable core there is sufficient activity space; Duplex sheath design has strengthened the resistance to low temperature of cable, between duplex sheath layer, lubricating layer is set simultaneously, improved the warp resistance performance of cable, has made up copper strips and put up the deficiency of the distortion performance of the screen of vertical bag; The screen of insulating barrier outside adopts copper strips to put up vertical packet form, forms totally-enclosed metal level, can reach effective function of shielding, is conducive to cable grounding simultaneously; The design of double layer screen, plays double shield to the shielding property of cable; Cable symmetrical structure, due to the interchangeability of conductor, makes the anti-interference between conductor better, works to suppressing electromagnetic interference.The wind power generation that cable of the present invention is particularly useful for low temp area uses.
Brief description of the drawings
Fig. 1 is the structural representation of the super cold-resistant cable for wind power generation of a kind of radiation proof that proposes of the present invention.
Embodiment
As shown in Figure 1, Fig. 1 is the structural representation of the super cold-resistant cable for wind power generation of a kind of radiation proof that proposes of the present invention.
With reference to Fig. 1, the super cold-resistant cable for wind power generation of a kind of radiation proof that the present invention proposes, comprises three conductors 1.
Put vertical three identical conductor 1 symmetrical parallel, in the outside coated nonwoven layer 2 with Z-Correct bump mapping Z-correct of all conductors 1, in the time of cable bend, make cable core there is sufficient activity space.The symmetrical construction of cable, due to the interchangeability of conductor 1, further plays the effect that suppresses electromagnetic interference, can offset the humorous odd frequency in that of high order, improves the anti-interference of cable, has reduced the electromagnetic radiation in whole system.The outside coated inner sheath 3 of nonwoven layer 2, the outside coated oversheath 5 of inner sheath 3, inner sheath 3 and oversheath 5 all adopt cold-resistant silastic material to make.
Between inner sheath 3 and oversheath 5, be provided with thin aluminium powder layer 4; this can make between internal layer cover 3 and oversheath 5 very lubricated; in the time that oversheath 5 is subject to twisting force; further protection inner sheath 3 and inner conductor 1; improve the warp resistance of cable, make up copper strips and put up the deficiency of the distortion performance of the screen 14 of vertical bag.And the setting of thin aluminium powder layer 4, when destroyed or breaking out of fire, is easy to from cable stripping oversheath 5 at oversheath 5.
Preferably, the cold-resistant silastic material that insulating barrier 13, inner sheath 3 and oversheath 5 adopt comprises following component according to mass fraction: 55-78 part low-phenyl silicone rubber, 15-45 part precipitated silica, 25-35 part rare earth oxide, 2.4-4 part ethene silicone oil, 0.1-0.5 part Pt catalyst; Particularly, 60 parts of low-phenyl silicone rubbers, 30 parts of precipitated silicas, 30 parts of rare earth oxides, 3 parts of ethene silicone oil, 0.2 part of Pt catalyst.This cold-resistant silastic material adopts low-phenyl silicone rubber material, has advantages of that temperature range is wide, mechanical property good; White carbon add the mechanical performance that has strengthened cold-resistant silicon rubber; Add rare earth oxide to play the effect of anti-irradiation.Sheath that this cold-resistant silastic material is made is cold-resistant heat-resisting, anticorrosion, resistance to wear is good, anti-radiation performance is good simultaneously, adopts the cable of this sheath to be particularly suitable for for a long time in the environment such as wind power generation and nuclear power.
