Embodiment Construction

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0033] Such as figure 1 As shown, a medium-voltage cable with a high compression coefficient ultra-smooth and corrosion-resistant aluminum alloy conductor includes a cable inner core and a cable outer layer wrapped around the cable inner core. The number of cable inner cores is one or more than one. In this embodiment, the number of cable inner cores is three. The inner core of the cable is an ultra-smooth aluminum alloy conductor with a high compression factor 1, a conductor shield 2, an insulation layer 3, an insulation shield 4 and a metal shield 5 from the inside to the outside. The outer layer of the cable is the tape 6, the flexible metal tube 7, and the sheath 8 in sequence from the inside to the outside. There is no filler between ...

Abstract

The invention discloses a high-compression-coefficient super-smooth corrosion-resistant aluminum alloy conductor medium-voltage cable which comprises a cable inner core and a cable outer layer lapped outside the cable inner core, and is characterized in that the cable inner core comprises a high-compression-coefficient super-smooth aluminum alloy conductor, a conductor shielding layer, an insulating layer, an insulation shielding layer and a metal shielding layer successively from inside to outside; and the cable outer layer comprises a lapping strip, a flexible metal tube and a protective sheath successively from inside to outside. According to the invention, the compression coefficient of the high-compression-coefficient super-smooth corrosion-resistant aluminum alloy conductor is up to over 95%, while the compression coefficient of an ordinary cable is only 88%-92%. Compared with a copper core cable, the cable provided by the invention has the advantages that on the basis of realizing equivalent electrical performance, the procurement cost can be reduced by 35%-40%, and the installation cost can be reduced by about 20%.

Description

technical field [0001] The invention relates to a power transmission cable, in particular to a medium-voltage cable with a high compression coefficient and an ultra-smooth aluminum alloy conductor. Background technique [0002] At present, medium voltage cable products use copper core cables and aluminum core cables. [0003] However, copper core medium voltage cables have the following problems: [0004] 1. From the perspective of copper and aluminum resources, the world is poor in copper and rich in aluminum; the price of copper is currently as high as 60,000 yuan / ton; [0005] 2. my country has become the world's largest consumer of copper, and the copper consumption of the cable industry accounts for about 47% of the total. [0006] 3. Traditional copper and aluminum core cables have low compression coefficient, and there are gaps between single wires, which are easy to oxidize and loosen, increase the DC resistance of the conductor, and directly affect the electrical ...
