| 发明名称 | High frequency cable, high frequency coil and method for manufacturing high frequency cable | ||
| 摘要 | A method for manufacturing a high frequency cable that includes covering a central conductor made from aluminum or an aluminum alloy with a covering layer made from copper; and wire drawing of the central conductor covered by the covering layer using dies at multiple steps, each of the dies having a cross-section reduction rate of 20% to 29% with an entire reduction angle of 16 degrees, to form a fiber-like structure in a longitudinal direction in the covering layer, and to form an intermetallic compound layer having greater volume resistivity than the covering layer between the central conductor and the covering layer. | ||
