Anti-oxidation anti-electric leakage aluminum core conductor

Abstract

The invention discloses an anti-oxidation anti-electric leakage aluminum core conductor, which is composed of an aluminum core conductor body, a buffer layer sputtered on the aluminum core conductor body and a silicon thin layer evaporated on the buffer layer. A smaller amount of carbon, silicon, manganese, sulfur, nickel, titanium, cobalt, and vanadium elements is added to the aluminum core conductor body; the buffer layer is an aluminum nitride layer; through firstly sputtering a buffer layer on the surface of the aluminum core conductor and then evaporating a silicon thin layer, the aluminum core conductor body is thus well compatible with the silicon thin layer, defects of lattice mismatching between the metal aluminum and the silicon are overcome, the silicon thin layer enables the outer surface of the aluminum core conductor not to be oxidized easily, galvanic corrosion is not generated when a copper conductor is connected, the heating amount is small, the structural design of the traditional transmission conductor is broken through, the aluminum core conductor is coated with a semiconductor layer and then coated with an insulated layer, electric energy loss generated in the case of transmission is less, and even when the insulated skin is damaged, electric leakage or electric shock accidents do not happen.

Description

technical field [0001] The invention relates to the technical field of aluminum core wire preparation, in particular to an anti-oxidation and anti-leakage aluminum core wire. Background technique [0002] Compared with copper core wire, aluminum core wire has the following advantages: [0003] (1) The price of aluminum core wire is cheap: copper rod is 3.5 times the price of aluminum rod, and the proportion of copper is 3.3 times that of aluminum, so aluminum core wire is much cheaper than copper core wire, suitable for low-cost projects or temporary electricity. [0004] (2) Light weight of the aluminum core wire: the weight of the aluminum core wire is 40% of that of the copper core wire, and the construction and transportation costs are low. [0005] Although the price of the aluminum core wire is cheap, the aluminum core wire is easy to oxidize and reacts with oxygen in the air to quickly form an oxide film. When copper and aluminum are connected, galvanic corrosion wil...

Problems solved by technology

[0005] Although the price of the aluminum core wire is cheap, the aluminum core wire is easy to oxidize and reacts with oxygen in the air to quickly form an oxide film. When copper and aluminum are connected, galvanic corrosion will occur, and the joint is prone to heat, which limits the application of the aluminum core wire.

At the same time, the traditional structural design of direct contact between the aluminum core wire and the insulating jacket causes a large electrical loss on the contact section when transmitting electric energy. If the insulating jacket is damaged, electric leakage accidents are likely to occur
