2. It is made by machining and welding, the basic supply being made of bent copper tubes. It may be delivered as a single piece or in separate elements. The connection between cables and electrodes is also made of copper tubes (unless conducting arms are used). The current densities are approximately the same as for the cables, or slightly higher.
它由機(jī)器制造或焊接而成,主要的導(dǎo)線由彎曲的銅管制成.電流會(huì)在單根導(dǎo)線或多根導(dǎo)線中傳輸.
電纜和電極的連接處同樣由銅管制成(除非使用支架).電流的密度和電纜的密度幾乎相同或稍微高一點(diǎn).
3. These busbar systems supply, among others, DC arc furnaces and graphitisation furnaces. They are made of large aluminium profiles (ex : 400 x 150mm) cooled by natural convection in the air, or in some cases large diameter tubes (the thickness being larger than that of copper tubes).
鋁母棒系統(tǒng)用于直流電電弧爐和石墨化爐.它是用在空氣中自然冷卻的大鋁制品(大約400x150mm)做成.有時(shí)也由大直徑的鋁管制成(厚度比銅管大).</DIV>
