Abstract
The invention discloses an aluminum wire armored ultrahigh pressure power cable which comprises a conductor positioned in the center, wherein a shielding layer, an insulating layer and an insulating and shielding layer are arranged outside the conductor in sequence; a semiconductive buffer strip is lapped outside the insulating and shielding layer; an aluminum wire armored layer is arranged outside the semiconductor buffer strip; and an outer jacket is extruded at the outmost layer. According to the invention, due to the adoption of the armored layer, an interior insulating wire core is not easy to damage in the production process, and a plurality of aluminum wires are armored to be capable of bearing tension force in the vertical direction; meanwhile, an appropriate number of the armored aluminum wires are selected to meet the requirements of single-phase short circuit.
Description
Technical field
The invention belongs to the power cable field, specifically is a kind of aluminium wire armouring type ultrahigh voltage power cable.
Background technology
Now, China 110KV, 220KV extra-high-tension cable are used in electric power system widely.The use of extra-high-tension cable has multiple environment to lay, also different for its requirement of different environment to cable, the extra-high-tension cable of making is a pattern basically at present, waterproof construction wherein is generally wrapped waterstop as vertical waterproof, weld or extrude radially waterproof of aluminium cover conduct, such product can satisfy waterproof requirement, but not high for waterproof requirement, even need not water resistant or waterproof environment (indoor or water-less environment), it is higher that the manufacturing cost of this product just seems.In addition, in the extra-high-tension cable manufacturing field, when corrugated aluminum sheath being adopted welding or extruding,, there is the potential product defective, reduces properties of product because the improper insulated wire cores that easily causes of temperature control is damaged; In addition, extra-high-tension cable is generally had relatively high expectations, and the fault single-phase short circuit current is big, structurally also must take into account.
Summary of the invention
Technical problem to be solved by this invention provides a kind of a kind of aluminium wire armouring type ultrahigh voltage power cable that bears pulling force during at water-less environment and vertical run and design, this cable is easy damaged built-in electrical insulation core not in process of production, this cable has reduced cost satisfying on the basis of serviceability, and the aluminium wire armour can also satisfy the requirement to single-phase short circuit.
Aluminium wire armouring type ultrahigh voltage power cable of the present invention, this cable comprises the conductor that is positioned at the center, outside conductor, set gradually conductor shield, insulating barrier and insulation screen, wrapped semi-conductive buffer band outside insulation screen, the aluminium wire armour is set outside the semi-conductive buffer band, and outermost layer extrudes oversheath.
The thickness of above-mentioned semi-conductive buffer band is preferably 0.5mm.
The present invention is from saving cost and reducing the environmental pollution angle, adopt simple effective method to solve the required pulling force problem of bearing of vertical run under the condition that extra-high-tension cable lays environment satisfying, this cable also need not to adopt pitch to carry out surface treatment in process of production, not only save the energy, and can not produce any environmental pollution in the production process.This cable is owing to adopt armour, and easy damaged built-in electrical insulation core not, and multiple aluminium wire armouring in process of production can bear the pulling force of vertical direction, selects for use suitable armouring aluminium wire radical to satisfy requirement to single-phase short circuit too simultaneously.
Description of drawings
Fig. 1 is a cross section structure schematic diagram of the present invention.
Embodiment:
As shown in Figure 1, aluminium wire armouring type ultrahigh voltage power cable of the present invention, this cable comprises the conductor 1 that is positioned at the center, outside conductor, set gradually conductor shield 2, insulating barrier 3, insulation screen 4, semi-conductive buffer band 5, aluminium wire armour 6 is set outside semi-conductive buffer band 5, and outermost layer extrudes oversheath 7.
Operation principle of the present invention: because extra-high-tension cable is generally had relatively high expectations; the fault single-phase short circuit current is big; in actual production process, utilize the operation principle of wire armoring machine; semi-conductive buffer band at the wrapped one deck 0.5mm thickness in insulated wire cores surface; play the effect of protection insulated wire cores, carry out the aluminium wire armouring, need not to extrude separation sleeve at the semi-conductive buffer belt surface; directly carry out the production of oversheath, not only simply but also the big cost of having saved.The multiple aluminium wire armouring can bear the pulling force of vertical direction, select for use suitable armouring aluminium wire radical to satisfy requirement too simultaneously to single-phase short circuit, only need the logical armoring machine of a Daepori to substitute aluminium press or argon arc welding machine during manufacturing, the risk of having avoided insulated wire cores to be scalded fully.
Production technology of the present invention is: advanced column conductor 1 is stranded, carry out subsequently realizing in the cross-linking process that conductor shield 2, insulating barrier 3 and insulation screen 4 are three-layer co-extruded, wrapped afterwards semi-conductive buffer band 5, on common armoring machine, carry out the aluminium wire armouring and form aluminium wire armour 7, extrude oversheath 7 at last.
The invention provides a kind of thinking and method of aluminium wire armouring type ultrahigh voltage power cable; the method and the approach of this technical scheme of specific implementation are a lot; the above only is a preferred implementation of the present invention; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.The all available prior art of each component part not clear and definite in the present embodiment is realized.
