Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for manufacturing a high frequency cable, comprising: 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.
