The present invention relates to a nickel (Ni) plated bus bar (bus bar), particularly relates to a bus bar is improved to improve the electrical conductivity, lightweight and reinforced strength.

In general, the bus bar (bus bar) has been used a lot of cables (CABLE) in the past as a medium for transmitting electrical energy, but because of the many advantages of the bus bar has been used as a replacement of the cable (CABLE).

The similarity when comparing bus bars and cables structurally is that they have conductors and insulators, but the great advantage of bus bars is that they can deliver more electrical energy in the same volume of conductors.

The cable uses vinyl or rubber to protect or insulate the conductor, but the busbar uses a metal duct to protect the busbar, so the conductor and insulator ( Protect and maintain shape.

The use of these busbars is rapidly increasing due to the recognition of the advantages of large-capacity systems, and nowadays, the systems of buildings are larger and require more energy. It has low energy loss and can be installed in harmony with modern buildings.

For example, busbars can be used in factories, buildings, apartments, large discount marts, officetels, research complexes, department stores, golf courses, tunnel semiconductors, LCD factories, chemicals, refineries, steelmaking, skyscrapers, ultra-high voltage substations, LNG transfer stations, new airports, ports It is supplied in various fields in various fields.

Meanwhile, as shown in FIG. 1, a bus bus bar 20 having a protective film 21 coated thereon is used as a conventional bus bar, and the copper bus bar 20 is a duct 10. Guided to ensure that power is supplied to the desired location.

However, the conventional bus bar 20 is not only economically burdened by using copper (Cu) as a whole, but also has to be cumbersome to install due to the heavy load of the duct 10 for guiding the same.

The present invention has been created to solve the above problems and has the following objectives.

First, it is an object of the present invention to provide a bus bar for improved electricity so that the strength is reinforced than the conventional bus bar and electrical conductivity is not lowered.

Second, the purpose of the present invention is to provide a busbar that is more economical than the conventional busbar and has improved electrical conductivity.

The present invention to achieve the above object is in a bus bar for electricity transmission,

The body of the bus bar is formed of a predetermined length aluminum bar,

Nickel plated film formed by plating nickel (Ni) on the surface of the aluminum bar,

A silver plating film formed by plating silver (Ag) on the surface of the nickel plating film,

It is characterized by consisting of a protective film provided on the surface of the silver plated film to protect the silver plated film.

In addition, the inventive bus bar is characterized in that a copper (Cu) plated film is further formed between the nickel plated film and the silver plated film.

According to the above features of the present invention, the inventive busbars have a silver plated film on the aluminum bar to improve conductivity and economically reduce cost, and are easy to install because they are made lighter than conventional copper busbars. Also

Strength is enhanced by forming a nickel plated film and a copper plated film.

In addition, the silver plating film, nickel plating film and copper plating film is formed on the surface of the aluminum bar by plating, thereby minimizing the manufacturing defect rate by maintaining the integration even by impact.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The bus bar of the present invention is designed to reduce costs, improve weight, and improve strength and electrical conductivity. This bus bar has a larger amount of energy transfer, easier load branching, and simpler wiring structure than a conventional cable.

Referring to FIG. 2, the inventive bus bar has a predetermined length of an aluminum bar 30 and a nickel plated film 31 formed to reinforce strength by plating nickel (Ni) on a surface of the aluminum bar 30. And a silver plating film 32 formed by plating silver (Ag) on the surface of the nickel plating film 31 and a protective film 34 formed on the surface of the silver plating film 32.

The protective layer 34 may be formed by coating or by inserting a tube.

Such a bus bar is guided to the desired position in the metal duct 10.

Meanwhile, referring to FIG. 3 as another embodiment of the inventive bus bar, it is a structure in which a copper (Cu) plated film 33 for strength reinforcement is further formed between the nickel plated film 31 and the silver plated film 32. Has

In the above, the aluminum bar 30 is formed in a predetermined length by extrusion, it is installed by connecting to each other to the desired position.

The manufacture of the busbar for electricity delivery as described above is as follows.

Referring to FIGS. 3 and 6, a pretreatment step of forming a predetermined length of the aluminum bar 30 and removing oil and stains present on the surface, and first washing the aluminum bar 30, and 1 Surface treatment with sulfuric acid or nitric acid to prevent stains due to the washings on the surface of the secondary washed aluminum bar 30, secondary cleaning after the surface treatment, and nickel on the surface of the aluminum bar 30 Plating and washing (Ni), followed by sequentially performing copper (Cu) and silver (Ag) plating, and performing a third wash.
