Abstract

PURPOSE:To adapt easily to the environment by constituting a pipe jamper device for overhead transmission line of an aluminum pipe having roughened surface applied with porous anode oxidized film of 0.3-0.5mum thick. CONSTITUTION:Surface of an aluminum pipe or an aluminum angle is sand blasted with abrasive, e.g. corundum, silicon carbide, silica sand, of #60-300 grain size thus roughening the surface with average roughness of 0.5-5mum and maximum roughness of 5-50mum. Thus roughened surface is then immersed in weak alkaline degreaser or washed with water thus removing the abrasive. It is then subjected to anode oxidization thus forming a porous anode oxidized film of 0.3-5mum thick. Anode oxidization is not limited to DC current. A light beam impinging on the film repeats refraction and random reflection thus lowering the brightness. An aluminum member applied with such surface treatment is employed in the fabrication of a pipe jamper for transmission line. According to the method, a jamper having brightness adaptable to the environment can be fabricated easily.

<Prior Art><Problems to be Solved by the Invention> With the increase in demand for electric power in recent years, there is a tendency for power transmission lines to become larger in size, multi-conductor, and multi-circuit.

In addition, due to site conditions, the transmission route for transmitting electricity from large-capacity power plants to urban areas may vary depending on the national, national, or national government.
Increasingly, power transmission lines must be constructed through environmentally protected areas such as national parks.

Power transmission equipment such as power transmission lines and steel towers installed in such scenic areas are required to have an appearance that is in harmony with the surrounding environment. However, in the past, for overhead aluminum power transmission lines such as AC3R, technology was applied to process them so that they would blend in with the surrounding environment, and consideration was given to brightness and reflectance, but no jumper devices were used. At present, it is being used as is without any consideration. That is, in the past, jumper devices with a metallic luster as manufactured were used, and even though the problem of damaging the environment was solved from the perspective of power transmission lines, they were still criticized as insufficient.

Especially in pipe jumper devices used for UHV power transmission lines (1 million pols), the aluminum pipes are large, about 20 cm in diameter and 20 m long, so they are very conspicuous and there is no way to dispose of them. Continuing to use it as it is is a problem because it will seriously detract from the beauty of the surrounding area.

Although this method reduced the reflectance, it had the opposite effect in terms of brightness, as it made the image appear white.

Also, a method of applying black paint to the steel tower itself has been considered, but this method cannot be applied to the aluminum pipe of the jumper equipment even though it is on the steel tower side because the coating film is electrically insulating. Furthermore, when connecting aluminum pipes to pipe spacers or attaching parts such as pipe connection terminals, the paint film on those parts must be peeled off.
There is a problem in that the installation work is troublesome.

It is also possible to make the paint film conductive so that the peeling work of the paint film is not necessary, but this type of paint not only tends to cause color unevenness, but also because it is made conductive. This method cannot be put to practical use because the carbon blank added to it has the negative effect of facilitating the formation of local batteries and accelerating corrosion of the aluminum pipe.

The blasting conditions for performing this surface roughening treatment may be those commonly used, and as the abrasive, a variety of materials such as corundum, silicon carbide, and silica sand can be used. The particle size of the abrasive may be appropriately selected in the range of #60 to #300 depending on the shape and material of the /f tube.

Furthermore, if the blasting process is a two-stage process, for example, the first stage is blasted with a coarse-grained abrasive, and the second stage is blasted with a fine-grained abrasive to create a more complex surface roughening state. The reduction in brightness is further promoted. In this blasting process, it is important to roughen the entire surface almost uniformly and evenly in order to form a porous anodic oxide film and obtain an overall uniform state without color unevenness.

In the present invention, the thus roughened surface is anodized in an acidic bath such as sulfuric acid to form a porous anodic oxide film. After the roughening treatment, it is preferable to remove the abrasives remaining on the surface during the roughening treatment by washing with water or immersing in a weakly alkaline degreaser bath.

Furthermore, in order to form a porous anodic oxide film on the surface of a roughened and cleaned aluminum pipe, it is necessary to use an aqueous solution containing an electrolyte that forms a porous film, such as sulfuric acid, oxalic acid, or phosphoric acid.

The current waveform for anodic oxidation may normally be direct current, but any other waveform may be used as long as it can form a porous film, such as alternating current, AC/DC superimposition, pulse, and incomplete rectification.

If the thickness of the alumite film to be formed is too thin (less than 0.3 μm), the brightness will not decrease, while if the film thickness exceeds 5 μm, the brightness will become too low and it will become electrically insulating, so it is preferably 0. A range of .3 μm to 5 μm is preferable.

By the way, porous oxide films are usually colorless, so even if an alumite film is formed on a smooth aluminum surface, no decrease in brightness will be observed, but an anodic oxide film will be formed on a finely roughened surface. When this happens, a product with significantly reduced brightness is obtained.

Although the reason for this is not clear, the growth direction of anodized aluminum film is generally perpendicular to the surface of the base metal, so it grows in multiple directions in response to minute uneven surfaces, and as a result, the film grows from different directions. A discontinuous surface is created at the joint surface between the two. This is thought to be due to the fact that if the film is further grown after such a stage, the growth direction of the film becomes very complicated.

このような皮膜では入射した光は屈折や乱反射が多数繰
り返され、明度が低下するものと考えられる。
It is thought that in such a film, incident light is repeatedly refracted and diffusely reflected, resulting in a decrease in brightness.
