Compare with the prior art product, this product supporting wind generating set use, is applicable to and lays transmission line in MW level normal atmospheric temperature, high temperature, low temperature, high height above sea level, the land wind generating set tower section of thick bamboo perpendicularly.
Description
Technical field
The technical program belongs to cable technology field, specifically a kind of tower cylinder cable.
Background technology
In prior art, wind-driven generator is more and more to be employed. The geographical environment of wind-power electricity generation place wind field is manyNumber is more severe, such as low temperature, high temperature, high height above sea level, salt fog etc. Meanwhile, along with passage of time, cable alsoThere will be creep. Different from the cable of other field of employment, after wind energy turbine set is built up, due to geographical position spyDifferent line upkeep is more difficult, the especially cable in the tower cylinder of wind-powered electricity generation unit, and it is larger that it changes difficulty. Secondly,The shortcoming of copper core cable is that price is high, weight is heavier, construction and cost of transportation high.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the technical program proposes a kind of new tower cylinder electricity consumptionCable, its structure is: form conductor by many Al-alloy metal monofilament are stranded; Conductor is wrapped with isolation strip; EveryFrom band outer wrapping insulating barrier; Insulating barrier outer wrapping sheath; The diameter of the Al-alloy metal monofilament that described conductor adoptsScope 1.0mm～4.0mm. The stranded lay of Al-alloy metal monofilament is not more than 14 times of stranded rear conductor diameter.Isolation strip is non-hygroscopic twining package tape, adopts overlapping wrapped mode, and the wrapped width of putting up is not less than 5mm.
The main component of Al-alloy metal monofilament comprises Al, Si, Fe, Cu, Mg, Zn and B.
Insulating barrier is closely extruded in surface, isolation strip; The Insulation Material of insulating barrier is: high electrical, resistance to-40 DEG C of low temperature,Soft type and thermosetting. Specifically, Insulation Material can be that ethylene propylene rubber insulation material (meets the electrical property of cableOutside requirement, also can meet-40 DEG C of cryogenic tensile rate measured values and be not less than 50%, low temperature performance excellent).
Sheath is evenly closely extruded in surface of insulating layer; The protective cover material of sheath require be adopt weather-proof, salt spray resistance,The thermosetting mixture of resistance to-40 DEG C low temperature, flame retardant type. Specifically, protective cover material can be the cold-resistant CPE of thermosettingMixture, the oxygen index (OI) of sheath is not less than 30%.
And-40 DEG C of cryogenic stretching performance excellences, measured value is greater than-50% extensibility requirement of national Specification.
Compared with prior art products, the supporting wind power generating set of this product is used, be applicable to MW level normal temperature,Vertical run transmission line of electricity in high temperature, low temperature, high height above sea level, land tower barrel of wind generating set.
Brief description of the drawings
Fig. 1 is the radial section schematic diagram of the present embodiment cable, in figure: Al-alloy metal monofilament 1, isolation strip2, insulating barrier 3, sheath 4.
Detailed description of the invention
The technical program is further illustrated as follows below in conjunction with specific embodiment:
As Fig. 1, a kind of new tower cylinder cable, its structure is: form by many Al-alloy metal monofilament are strandedConductor; Conductor is wrapped with isolation strip; Isolation strip outer wrapping insulating barrier; Insulating barrier outer wrapping sheath; Described leadingDiameter range 1.0mm～the 4.0mm of the Al-alloy metal monofilament that body adopts. The main one-tenth of Al-alloy metal monofilamentDividing is Al, silicon addition, Fe, Cu, Mg, Zn and the B etc. of interpolation. Al-alloy metal monofilament is strandedLay be not more than 14 times of stranded rear conductor diameter. The material of described sheath is weather-proof, salt spray resistance, resistance to-40The thermosetting mixture of DEG C low temperature, flame retardant type; The material non-hygroscopic twining package tape of isolation strip, adopts overlapping wrappedMode, the wrapped width of putting up is not less than 5mm; The Insulation Material of insulating barrier is high electrical, resistance to-40 DEG C of low temperature, softSoft type thermosetting mixture; To adopt to extrude mode and be wrapped in outside isolation strip; Evenly closely being extruded in absolutely of sheathEdge layer surface.
Specifically, Insulation Material can be ethylene propylene rubber insulation material, and protective cover material can be the cold-resistant CPE of thermosettingMixture, the oxygen index (OI) of sheath is not less than 30%.
Compared with similar products, the feature of this power cable mainly comprises:
1) light-duty
This aluminium alloy compared with copper, the direct cost of aluminium alloy cable be cable itself cost than copper cable saving approximately35%, because the bending property of aluminium alloy cable is better and weight is lighter, can be in order to avoid crane span structure or minimizing crane span structure consumption,Be mounted to instinct and save 20%～50%, and the external diameter of aluminium alloy cable after substituting only increases than copper cable10% left and right, thereby can not have influence on installation connection.
2) good fire resistance
Through third party's pattern detect, finished cable respectively by GB/T18380.12 single do not prolong combustion (,GB/T18380.35 bunchy fire retardancy test.
3) creep-resistant property excellence
Detect through third party's pattern, complete the test of system connectivity and resistance to compression creep with copper-aluminium transition wire barrelTest.
