导电部分

每极由三个独立的单极组成，每个单极是由底座、绝缘支柱及导电部分组成。

Each pole is composed of three independent single poles and each single pole is composed of base , insulator supporter and conductive parts .

将建筑物电气装置内外露的可导电部分、电气装置外的可导电部分、人工或自然接地体用导体连接起来，以达到减少电位差成为等电位联结。

Connect the exposed conductive part of the electric device , the conductive part out of the electrical device , and the manual or natural earthing with conduc - tor to reduce the opportunity that the potential difference becomes potential connection .

由于铝与铜的物理性能相近，可作为导电材料替代部分铜材，但是因为Al表层极易生成氧化膜，给铝的焊接带来了许多困难，导致铝的应用范围受到限制。

Aluminium can be used as substitute conductive materials Due to the similar physical properties of Al and Cu . But the strong surface oxidation films takes many difficulties for welding and thus constricts the application field of Al .

采用压片法制备了空气电极。空气电极由催化层和导电铜箔两部分组成。

Air electrode was prepared by pressing catalyst layer / copperscreen together . 2 .

目前在SF6断路器中普遍使用的触头材料一般由耐电弧烧损的CuW部分和提供弹性和导电性的CrCu部分组成，即CuW／CrCu整体触头。

At present , the arc contacts in SFe switches is formed by the excellent property of electrical arc resistance of Cu W alloy and the eminent conductivity together with high elasticity of CrCu alloy , so-called CuW / CrCu integrated contact .
