摘要： In a copper-clad steel trolley wire, the peripheral surface of a core (1), formed of a steel wire, is covered by a copper or copper-alloy covering layer (2). Forty-five to 75 % of the cross-sectional area of the copper-clad steel trolley wire is occupied by the covering layer (2). The core (1) and the covering layer (2) are metallurgically bonded to each other.
Even if the covering layer (2) is worn away so that the core (1) is exposed, corrosion cannot advance at the boundary between the core (1) and the covering layer (2), since the core and the covering layer are firmly metallurgically bonded to each other.
The composite cast rod, obtained by the dip forming method, is hot-rolled under predetermined conditions so that the copper or copper-alloy covering layer is metallurgically bonded to the steel core. Thus, the copper-clad steel trolley wire with a uniform covering layer thickness can be manufactured at low cost.摘要翻译： 在铜包钢电车线中，由钢丝构成的铁心（1）的外周面被铜或铜合金覆盖层（2）覆盖。 覆铜层电线线的横截面积的45％至75％被覆盖层（2）所占据。 芯部（1）和覆盖层（2）彼此冶金结合。 即使覆盖层（2）被磨损以使得芯（1）暴露，由于芯和覆盖层牢固地在芯（1）和覆盖层（2）之间的边界处不会发生腐蚀， 冶金结合。 通过浸渍成形法得到的复合铸造棒在规定的条件下热轧，铜或铜合金被覆层与钢芯冶金结合。 因此，可以以低成本制造具有均匀覆盖层厚度的铜包钢电车线。
