Description
Technical field
The present invention relates to electric wire field, and in particular to a kind of anti-interference crosslinked polyetylene insulated medium voltage electricity electricity of tension
Cable.
Background technology
Cable laying is not taken up an area face, space, it is attractive in appearance to be advantageous to the appearance of the city in underground in city；Same buried cable leads to
Road, multi circuit transmission lines, the strong adaptability of transmission capacity can be accommodated；Natural conditions（Such as thunder and lightning, wind and rain, salt fog, filth）And week
Influence of the collarette border to cable is smaller, and power supply reliability is high；Cable is hidden in underground, safer to the person；Physical loop cabinet,
The equipment such as distribution box, multi-line contact can be carried out, form supply network, the method for operation is extremely flexible, can reduce power failure time significantly
Number and power failure range, easily realize distribution automation.The system of laying that city inner cable uses at present typically mainly has direct-burried to apply
If, cable installation in pipe, cable duct laying, tunnel laying etc. mode, directly buried installation mode is most passed through in all underground laying modes
The system of laying that Ji, difficulty of construction are minimum, construction speed is most fast, but this system of laying cable is easily damaged, service life
It is short, directly affect the confidence level of this system of laying.
With increasing rapidly for national economy, cities and towns power consumption is continuously increased, and people constantly carry to the dependence of electric energy
Height, by present with the improvement of construction of cable form with improve the construction speed of the laying of cable, reduce because cable laying is applied
The inconvenient time that work is brought to civil plantation is the final purpose of this project development.
The content of the invention
In order to overcome the deficiencies in the prior art, there is provided a kind of good insulation preformance, loss is low, service life is long, anti-
The crosslinked polyetylene insulated medium-pressure power cables of characteristic such as interference.
To achieve the above object, the present invention, which provides, hands over a kind of anti-interference crosslinked polyetylene insulated medium-pressure power cable of tension,
Including three copper conductors, co-extruded cross-linking polyethylene insulation tube forms insulated wire cores outside three copper conductors, the weight outside insulated wire cores
The wrapped copper covered steel band screen layer of lid is stacked with, every layer of overlapping width put up is not less than wide 20% of steel band, the wrapping angle of copper covered steel
No more than 30 °；Silicon rubber separation sleeve is externally provided with copper covered steel band screen layer, silicon rubber separation sleeve is externally provided with environmentally friendly high fire-retardance alkali-free
Glass cloth braid over braid, it is externally provided with non magnetic steel wire in high fire-retardance alkali-free glass cloth braid over braid and adds armour of the non-magnetic steel with metal structure
Layer is filled, is finally externally provided with polyvinyl fluoride oversheath in cable.
Preferably, blocked water between the silicon rubber separation sleeve and environmentally friendly high fire-retardance alkali-free glass cloth braid over braid provided with PVC thin
Film, it can also play a part of blocking water.
Preferably, copper part of the described copper covered steel with screen layer is more than 99.95% oxygen-free copper, conductance using purity
Not less than 102%, cable current capacity ensure that；The steel part of copper covered steel uses No. 304 steel of austenite, because its for it is non magnetic not
Become rusty Steel material, can avoid tape loss and eddy-current loss caused by alternating current transmission, and can preferably play shielding electric field
Effect.
Compared with prior art, the beneficial effects of the present invention are：
1st, insulation uses crosslinked polyetylene insulated pipe, instead of the structure that an existing conductor one insulate, not plasticizer-containing, will not
Go mouldy and breed bacteria, heat-resist, normal operating temperatures can be subjected to 110 DEG C of environment lower 8000 hours up to 95 DEG C, pressure-resistant
Performance is good, corrosion resistance and good, is amenable to the corrosion of most of chemicals, good heat-insulation effect, saves the energy, can be arbitrarily curved
Song, will not embrittlement, under equal conditions, water-carrying capacity is bigger than metal tube, and creep strength is high, can match somebody with somebody metal tube, can save connection
Pipe fitting, installation cost is reduced, accelerate installation period, be easy to repair, the key property of crosslinked polyethylene pipe is its intensity and resistance to
Warm nature energy, particularly its creep strength, its intensity is not notable with the change of usage time, and the life-span was up to 50 years as long as.
2nd, the metal screen layer, the non magnetic steel wire that set copper covered steel are added into the structure shapes such as non-magnetic steel band metal armor layers
Formula, to reach good pull resistance, anti-interference, service life length and other effects.
3rd, compression strength brings up to 5000N/m by the 3000N/m of standard, and tensile capacity improves 35%；In cable laying
When, the hauling speed of cable brings up to 20m/min by 15m/min；The degree of eccentricity of insulated wire cores is not more than 15% as defined in standard
It is reduced within 5%.
4th, cable is to be improved for directly buried installation with the shortcomings that presence of cable, and increases new functional characteristics, is made
Speed of application is improved, and the impaired probability of cable reduces in work progress and normal course of operation, and it also has absolutely
Edge performance is good, loss is low, service life is long, the characteristic such as anti-interference, and small with bending radius, the advantages that being easy to laying.
