Corrosion-resistant self-damping energy-saving aluminum conductor steel reinforced

Abstract

The invention discloses a corrosion-resistant self-damping energy-saving aluminum conductor steel reinforced. The corrosion-resistant self-damping energy-saving aluminum conductor steel reinforced comprises a cable core. The cable core is formed by twisting center aluminum-clad steel wires, an aluminum-clad steel wire layer and an anticorrosion ointment, wherein the aluminum-clad steel wire layer is formed by concentrically extruding the aluminum-clad steel wires, and the gaps between the aluminum-clad steel wires and the aluminum-clad steel wire layer are filled up with the anticorrosion ointment. The cable core is externally successively provided with an inner aluminum wire layer and an outer aluminum wire layer, and the anticorrosion ointment fills the portion between the cable core and the contact surface of the inner aluminum wire layer and the portion between the contact surface of inner aluminum wire layer and the contact surface of the outer aluminum wire layer. According to the invention, on one hand, the outer layers of the aluminum-clad steel wires are provided with aluminum, there is no potential difference between the aluminum-clad steel wires and the aluminum wires at the outer layer, and electrochemical corrosion is not generated; and on the other hand, Z-shaped aluminum wires and S-shaped aluminum wires are tightly combined, slits are small, and the anticorrosion ointment also fills the slits, such that it is difficult for a salt mist to penetrate into the twisted slits of the aluminum wires, and the slits are prevented from being corroded.

Description

technical field [0001] The invention belongs to the field of electric wires, and in particular relates to a super-corrosion-resistant self-damping energy-saving steel-cored aluminum stranded wire. Background technique [0002] Ordinary steel-reinforced aluminum strands are twisted by steel wires on the inner layer and round aluminum wires on the outer layer. There is a large gap between the round aluminum wires. In coastal areas, in corrosive salt spray atmospheres and humid heat Under severe weather conditions, salt spray can easily enter the steel wire layer through the gaps between the round aluminum wires, and electrochemical corrosion will occur between the steel wires and the aluminum wires. In addition, due to the large gaps between the aluminum wires, crevice corrosion will also occur under the action of salt spray. Both galvanic corrosion and crevice corrosion can lead to breakage of aluminum wires. [0003] Due to structural reasons, the contact area between the ...

In addition, due to the large gaps between the aluminum wires, crevice corrosion will also occur under the action of salt spray.

Both galvanic corrosion and crevice corrosion can lead to the breakage of aluminum wires

[0003] Due to structural reasons, the contact area between the single wires of ordinary steel-cored aluminum stranded wires is small and does not have self-damping characteristics, and single wires are prone to breakage under the action of wind force

[0004] Ordinary steel-cored aluminum stranded wire uses a steel core in the middle, the electrical conductivity of the steel wire is checked, the outer diameter of the stranded wire is large, and it does not have energy-saving performance
