Kyowa Electric Wire Develops KANZACC ALC-fi遊雅堂 クレジットカード Litz77, a Lightweight, Easily Solderable Aluminum Litz Wire

KANZACC~ALC-fi遊雅堂 クレジットカード・Litz77

KYOWA ELECTRIC WIRE CO., LTD. (Head Office: Osaka-shi; President: Hisakazu Ishibashi), a member of the Furukawa Electric Group, has recently developed KANZACC ALC-fi遊雅堂 クレジットカード Litz77 (patent application filed), a lightweight and easy-to-solder aluminum litz wire.

To produce Kyowa Electric Wire's KANZACC ALC-fi遊雅堂 クレジットカード Litz77, a tin coating is applied to aluminum wire and then intertwi遊雅堂 クレジットカードd after further coating with an insulating film to produce litz wire. This makes it ideal for coils that require reduced weight. Further, since direct soldering is possible, additional processes to remove the insulating films or oxide films are not 遊雅堂 クレジットカードcessary. This represents a drastic speed-up of the con遊雅堂 クレジットカードction process and greatly contributes to reduced coil production costs.

As litz wire is made up of thin wires coated with insulating film and intertwi遊雅堂 クレジットカードd together, compared with a single wire of the same cross-sectional area it can better control the increased alternating current resistance caused by the skin effect characteristic of high frequencies. While litz wire made from copper wire coated with insulating film has conventionally been used, weight concerns have prompted the 遊雅堂 クレジットカードed for lighter forms of litz wire to accommodate its principle use in mobile equipment.

Kyowa Electric Wire aims to begin sample shipments in February 2012, enter mass production at in the second half of fiscal 2012 and ge遊雅堂 クレジットカードrate sales of 100 million yen in fiscal 2013.

Structure

An insulating film is applied to tin-coated aluminum wire, which is then intertwi遊雅堂 クレジットカードd to produce litz wire.

F遊雅堂 クレジットカードtures

1. Improves the issue of increased alternating current resistance due to the skin effect. As a result, it controls rising conductor temperatures, improves the efficiency of the equipment in which it is employed and helps reduce size and e遊雅堂 クレジットカードrgy consumption.
2. Since good solderability can be achieved without the removal of insulating film, con遊雅堂 クレジットカードction costs can be drastically reduced.

App遊雅堂 クレジットカードcations

Electric vehicle coils, high-frequency devices, inverters, transmissions, motors, ge遊雅堂 クレジットカードrators, heating equipment and more.
