Problems solved by technology

At the same time, we also know that copper is not resistant to seawater acid and alkali corrosion, and is not suitable for marine wind power environments. The inherent anti-corrosion performance of aluminum is due to the thin and strong oxide layer formed immediately when the surface is in contact with air

Embodiment Construction

[0023] Below in conjunction with accompanying drawing, illustrate the concrete content of the present invention in detail:

[0024] Such as figure 1 Extrude a silane cross-linked insulating layer 2 on the conductor 1 shown, then twist three extruded silane cross-linked insulating wires to form a cable core, use aluminum alloy tape self-locking armor 3 outside the cable core, and finally The outer sheath 4 is extruded from the armor layer 3 .

[0025] Adding iron, silicon, copper, magnesium, zinc, boron and other trace elements to the aluminum material improves the tensile strength, elongation and thermal expansion of the conductor, and reduces the temperature and extrusion of the conductor. "Creep" phenomenon;

[0026] The aluminum alloy conductors are produced by using the original type aluminum alloy conductors for inter-embedded stranding technology, which improves the conductivity of the aluminum alloy conductors, making them higher than pure aluminum and second only to ...

Abstract

The present invention discloses an aluminum alloy conductor wind energy cable for fixation and laying. The aluminum alloy conductor wind energy cable for fixation and laying is configured for a rated voltage 0.6/1kV low-voltage electric energy transmission system and is suitable for saline-alkaline resistance occasions. A traditional copper cable is not resistant to seawater acid and caustic corrosion and is not suitable for sea wind power environment, and the aluminum has inherent anticorrosion performance because of a thin and fastened oxide layer immediately formed when the surface touches the air. The oxide layer can especially tolerate the corrosion in various modes, the corrosion resistance of the oxide layer is greatly better than that of copper. The cable adds trace elements based on the aluminum to form aluminum alloy so as to improve the corrosion resisting performance and enhance the cable anti-compression performance by using a self-locking armor structure.

Description

technical field [0001] The invention relates to a power transmission system for a wind turbine fixedly laid on the sea, which can be used in coastal areas where acid and alkali are highly corrosive. Background technique [0002] As we all know, my country is short of copper resources, but rich in aluminum resources. With the advancement of science and technology, the pace of "substituting aluminum for copper" and "saving energy and reducing consumption" has accelerated. Under the same current carrying capacity, the actual weight of aluminum alloy is about two-thirds of that of copper, so the use of aluminum alloy cables instead of copper cables can reduce the weight of cables, reduce installation costs, reduce wear and tear on equipment and cables, and make installation easier . At the same time, we also know that copper is not resistant to seawater acid and alkali corrosion, and is not suitable for marine wind power environments. The inherent anti-corrosion performance of ...
