绝缘性导线的制备方法
摘要：
本发明公开一种绝缘性导线的制备方法，所述导线包括铜合金芯材，所述芯材外包覆的镍合金层，最外层为绝缘层，铜合金芯材的各组分质量百分含量为：Mg 0.6-0.9％、Zn 0.7-0.9％、Mn 0.3-0.4％、Sn 0.6-0.8％、Bi 0.6-0.7％、Al 0.5-0.6％、Ni 0.04-0.05％、Fe 0.06-0.07％、Co 0.04-0.05％、La 0.05-0.06％和Y 0.02-0.03％，余量为铜及不可避免的非金属夹杂，该绝缘性导线的制备方法通过对铜合金线材包覆镍合金和绝缘材料从而提高铜合金导线的耐候性，有效延长了其使用寿命。
摘要（英）：

The invention discloses a method for preparing an insulated wire. The wire comprises a copper alloy core material, a nickel alloy layer and an insulating layer, wherein the core material is covered with the nickel alloy layer, and the insulating layer is arranged on the outermost layer. The copper alloy core material comprises, by mass, 0.6-0.9% of Mg, 0.7-0.9% of Zn, 0.3-0.4% of Mn, 0.6-0.8% of Sn, 0.6-0.7% of Bi, 0.5-0.6% of Al, 0.04-0.05% of Ni, 0.06-0.07% of Fe, 0.04-0.05% of Co, 0.05-0.06% of La, 0.02-0.03% of Y and the balance being copper and inevitable non-metallic inclusions. According to the method for preparing the insulated wire, weather resistance of the copper alloy wire is improved by covering the copper alloy core material with nickel alloy and an insulating material, and the service life of the insulated wire is effectively prolonged.
