Description
Technical field
The utility model relates to a kind of cable, is specifically related to a kind of terminal direct current high voltage cable.
Background technology
Along with develop rapidly and the technological progress of national economy, HVDC Transmission Technology will be widely used in future electrical energy transmission, for strengthening electric power networks, reduce power outages, meeting the demand of future market.Current terminal tends to adopt direct current high voltage cable transferring electric power gradually, but current cable is not suitable for high direct voltage transmission, the shortcomings such as electrical property is undesirable, mechanical strength is low, resistance to elevated temperatures is not high.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of rational in infrastructure, good electrical property, mechanical strength are high, resistance to elevated temperatures good, the terminal direct current high voltage cable of corrosion resistance and good.
The utility model is achieved through the following technical solutions: a kind of terminal direct current high voltage cable, and its internal layer is followed successively by skin: multiply copper-covered aluminum-core, semiconductive belt, semiconductive conductor shield, drainage layer, flame retardant coating, insulating barrier, steel-tape armouring layer, anti-corrosion asphalt layer, hot melt adhesive layer, oversheath.
Further, described flame retardant coating is composite mica tape.
Further, described insulating barrier is that pvc material is made.
Further, described oversheath is that polyetheretherketonematerials materials is made.
Terminal direct current high voltage cable of the present utility model has good electrical property, mechanical strength is high, resistance to elevated temperatures good, corrosion resistance and good, the feature that reasonable in design, cost is low.
Accompanying drawing explanation
For ease of illustrating, the utility model is described in detail by following specific embodiment and accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Wherein: 1, multiply copper-covered aluminum-core, 2, semiconductive belt, 3, semiconductive conductor shield, 4, drainage layer, 5, flame retardant coating, 6, insulating barrier, 7, steel-tape armouring layer, 8, anti-corrosion asphalt layer, 9, hot melt adhesive layer.
Embodiment
Further specific descriptions will be done by specific embodiment to the utility model below below in conjunction with accompanying drawing, but can not be interpreted as it is restriction to the utility model protection range.
A kind of terminal direct current high voltage cable, its internal layer is followed successively by skin: multiply copper-covered aluminum-core 1, semiconductive belt 2, semiconductive conductor shield 3, drainage layer 4, flame retardant coating 5, insulating barrier 6, steel-tape armouring layer 7, anti-corrosion asphalt layer 8, hot melt adhesive layer 9, oversheath.Adopt copper-covered aluminum-core 1 as conductor, combine the characteristic of copper and aluminium, effectively compensate for and be used alone copper conductor and aluminium conductor defect in use, while reducing costs, improve the performance of product, the high pressure of more than 1,000,000 volts can be born; Semiconductive belt 2 is for uniform insulation electric field, and avoid electric field that change suddenly occurs on interface, thus puncture insulation, material is semiconductive material; Arranging semiconductive conductor shield 3 is because cable conductor forms by multiple conducting wires is stranded, easily air gap is formed between it and insulating barrier, conductive surface is rough, electric field can be caused to concentrate, the screen of one deck semiconductive material is added at conductive surface, the conductor equipotential of it and conductively-closed and with insulating barrier good contact, thus avoid, between conductor and insulating barrier, partial discharge occurs; The timely carrying-off of electric charge that described drainage layer 5 can produce semiconductive conductor shield 3; Described anti-corrosion asphalt layer 8 can improve the decay resistance of cable; Described hot melt adhesive layer 9 be used for bond described in anti-corrosion asphalt layer 8 and oversheath.
Particularly preferred, described flame retardant coating 5 is composite mica tape, improves resistance to elevated temperatures.
Particularly preferred, described insulating barrier 6 is made for pvc material, can bear higher temperature.
Particularly preferred, described oversheath is that polyetheretherketonematerials materials is made, and has stronger ageing-resistant performance and higher intensity.
Terminal direct current high voltage cable of the present utility model has good electrical property, mechanical strength is high, resistance to elevated temperatures good, corrosion resistance and good, the feature that reasonable in design, cost is low.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and the claimed scope of the utility model is defined by appending claims, specification and equivalent thereof.
