摘要：
本发明公开了一种耐高压高温导电线及其制备工艺，涉及电线电缆领域，该种导电线包括以下按重量百分比计的成份：Si 4.2‑5.8％、Cu 0.8‑1.2％、Sn 1.2‑1.6％、Co 0.6‑0.8％、Cr 0.5‑0.7％、Ti 0.4‑0.6％、Mn 0.2‑0.3％、Ni 0.1‑0.3％、Nb 0.08‑0.09％、Ba 0.06‑0.08％、Re 0.06‑0.08％、Zn 0.04‑0.06％和Hf 0.03‑0.05％，剩余量为Al和不可避免的非金属杂质。该导电线的制备工艺是通过对原料成份的分段熔炼‑静置扒渣‑精炼‑铸造‑固溶处理‑淬火‑人工时效‑多道次成丝后便制得本发明的耐高压高温导电线。本发明的导电线具有更高强度和更优良导电性能，且耐高温高压，经久耐用，使用寿命长，且其制备方法简便，适宜推广应用。
摘要（英）：

The invention discloses a high pressure and high temperature resistant electric lead and a preparation technology thereof, and relates to the field of cables and wires. The electric wire comprises, by weight, 4.2-5.8% of Si, 0.8-1.2% of Cu, 1.2-1.6% of Sn, 0.6-0.8% of Co, 0.5-0.7% of Cr, 0.4-0.6% of Ti, 0.2-0.3% of Mn, 0.1-0.3% of Ni, 0.08-0.09% of Nb, 0.06-0.08% of Ba, 0.06-0.08% of Re, 0.04-0.06% of Zn, 0.03-0.05% of Hf, the balance Al and unavoidable nonmetallic impurities. The preparation technology of the electric wire includes the steps of segmented smelting, standing and drossing, refining, casting, solution treatment, quenching, artificial aging, and multi-pass filamentization of raw material elements, and thus the high pressure and high temperature resistant electric lead is obtained. The electric lead has higher strength and more excellent electrical conductivity, can resist high temperature and high pressure, and is durable, and long in service life, the preparation method is simple and convenient, and suitable for being popularized and applied.
