Title (EN) HIGH-STRENGTH CORROSION-RESISTANT ALUMINUM-CARBON-COPPER ALLOY GROUNDING MATERIAL
(FR) MATÉRIAU DE MISE À LA TERRE EN ALLIAGE ALUMINIUM-CARBONE-CUIVRE RÉSISTANT À LA CORROSION ET À HAUTE LIMITE ÉLASTIQUE
(ZH) 一种高强度耐腐蚀的铝碳铜合金接地材料
Abstract:
(EN) A high-strength corrosion-resistant aluminum-carbon-copper alloy grounding material, including the following components in percentage by mass: 46%-62% of aluminum, 2%-8% of copper, 1%-30% of carbon, impurities: iron <1.5%, silicon <1.5%, and others <1.0%. The corrosion resistance and grounding conductivity of the material are equivalent to those of pure copper. The addition of a carbon particle component improves the hardness and strength of the grounding material, the grounding material can be directly implanted in deep soil in bar form and used directly as a vertical ground, and the alloy has good soil corrosion resistance.
(FR) L’invention concerne un matériau de mise à la terre en alliage d'aluminium-carbone-cuivre résistant à la corrosion et à haute limite élastique, comprenant les éléments suivants en pourcentage en masse : de 46% à 62% d'aluminium, de 2% à 8% de cuivre, de 1 à 30% de carbone, les impuretés suivantes : <1,5% de fer, <1,5% de silicium, et <1,0% d’autres impuretés. La résistance à la corrosion et la conductivité de mise à la terre du matériau sont équivalentes à celles du cuivre pur. L'ajout d'un élément à particules de carbone améliore la dureté et la limite élastique du matériau de mise à la terre, le matériau de mise à la terre peut être directement implanté profondément dans le sol sous forme de barre et utilisé directement comme masse verticale, et l'alliage présente une bonne résistance à la corrosion en sol.
(ZH) 一种高强度耐腐蚀的铝碳铜合金接地材料,材料的质量百分比组成为:铝46%~62%,铜2%~8%,碳1%~30%,杂质:铁<1.5%,杂质:硅<1.5%,其它杂质的总含量<1.0%。该材料的耐腐蚀性和接地导通性与纯铜相当。由于碳颗粒成分加入,提高了接地材料的硬度和强度,可以直接以棒材形式打入深层土壤之中做垂直接地极使用,且合金具有良好的耐土壤腐蚀性。
