Abstract
The invention discloses a novel anti-tensile power cable with nickel conductors. The novel anti-tensile power cable comprises power wire cores, a shielding layer, an inner sheath layer, a silver-plated copper tape shielding layer, a silver-plated aluminum tape armor layer, a polyvinyl chloride insulating layer and an outer sheath layer, wherein each power wire core comprises one nickel conductor, a crosslinked polyethylene insulating layer, a non-magnetic metal armor layer and a metal fiber woven shielding layer; the inner sheath layer and the outer sheath layer are chlorosulfonated ethylene propylene sheath layers. The cable overcomes defects of cables with pure aluminum as conductors in the prior art and has the advantages of creep resistance, high flexibility, connection stability and the like, and besides, the cost of the cable is reduced by 50%.
Description
Technical field
The invention belongs to field of cables, particularly relate to a kind of New Nickel conductor tension power cable.
Background technology
Along with the development of China's industry, current China enters Electrification Age the most comprehensively, and power cable usage amount is the most increasing, and the conductor main component manufacturing cable is copper, accounts for about the 70% of total copper consumption.But China's copper resource is the shortest, along with the exhaustion of COPPER IN CHINA resource, COPPER IN CHINA 80% needs import, and dependency is big.Along with constantly riseing of copper valency, copper is replaced to be the inexorable trend that electric wire develops with aluminum.The electric wire more than 80% of France is aluminium conductor, and the aluminum conductor of Japan also accounts for more than 50%.China's bauxite resource is the abundantest, but application amount is less than 1%, is the most also because the immature caused of aluminum conductor manufacturing technology, and therefore obtaining technical breakthrough is the key solving this problem.
Past aluminium conductor electric wire, owing to the mechanical performances such as the intensity of aluminum and elongation percentage can not meet requirement, does not has again resistance effect simultaneously.So the most also there is no a kind of 6-35kV power cable having again block-water performance with cheap excellent performance.
Summary of the invention
This patent is for avoiding the weak point existing for above-mentioned prior art, it is provided that the one fine aluminium of solving over is used as electric wire and cable conductor and exists a lot of not enough, has the New Nickel conductor tension power cable of the advantages such as creep resistant, high pliable and tough and stable connection.
nullThe present invention takes techniques below scheme to realize: a kind of New Nickel conductor tension power cable，It is by power wire core、Screen layer、Inner restrictive coating、Silver-plated copper strips screen layer、Silver-plated aluminium strip armor、Polyvinyl chloride insulation layer and external sheath layer composition，Described power wire core is provided with three groups，Described power wire core is by nickel conductor、Crosslinked polyetylene insulated layer、Nonmagnetic metal armor and weaving metallic fibers screen layer composition，One layer of inner restrictive coating of the outer wrapping of described screen layer，The silver-plated copper strips screen layer of the outer wrapping of described inner restrictive coating one layer，The silver-plated aluminium strip armor of outer wrapping one layer of described silver-plated copper strips screen layer，The outer wrapping one strata vinyl chloride insulation layer of described silver-plated aluminium strip armor，One layer of external sheath layer of the outer wrapping of described polyvinyl chloride insulation layer，Described silver-plated copper strips screen layer is provided with three groups，Uniformly extrude in silver-plated aluminium strip armor，Described inner restrictive coating and external sheath layer are chlorosulfonation second propylene restrictive coating.
A length of 2 millimeters of the cross-sectional diameter of described nickel conductor.
The method have the advantages that the fine aluminium of solving over is used as electric wire and cable conductor and exists a lot of not enough in sum, there is the advantages such as creep resistant, high pliable and tough and stable connection, on the other hand also reduce the cost 50% of cable.
Accompanying drawing explanation
Fig. 1 is cross-sectional structure schematic diagram of the present invention.
Detailed description of the invention
nullAs shown in Figure 1，A kind of New Nickel conductor tension power cable，It is by power wire core 1、Screen layer 2、Inner restrictive coating 3、Silver-plated copper strips screen layer 7、Silver-plated aluminium strip armor 4、Polyvinyl chloride insulation layer 5 and external sheath layer 6 form，Described power wire core 1 is provided with three groups，Described power wire core 1 is by nickel conductor 11、Crosslinked polyetylene insulated layer 12、Nonmagnetic metal armor 13 and weaving metallic fibers screen layer 14 form，One layer of inner restrictive coating 3 of the outer wrapping of described screen layer 2，The silver-plated copper strips screen layer 4 of the outer wrapping of described inner restrictive coating 3 one layer，The silver-plated aluminium strip armor 5 of outer wrapping one layer of described silver-plated copper strips screen layer 4，The outer wrapping one strata vinyl chloride insulation layer 6 of described silver-plated aluminium strip armor 5，One layer of external sheath layer 7 of the outer wrapping of described polyvinyl chloride insulation layer 6，Described inner restrictive coating 3 and external sheath layer 7 are chlorosulfonation second propylene restrictive coating.
It is embodied as: a length of 2 millimeters of the cross-sectional diameter of described nickel conductor 11.
The above is the embodiment of the present invention, therefore all equivalence changes done according to structure, feature and the principle described in the present patent application scope or modification, in the range of being all included in present patent application.
