ISOLIERTE DRAHTLITZE.

摘要

The insulated electric wire of the invention is applicable for wirings and windings used in a high-vacuum or high-temperature environment, that is within high-vacuum or high-temperature equipment. This wire comprises a base member (1), an anodically oxidized layer (2), and an oxide insulating layer (3). The base member (1) includes a conductor and has at least on the outer surface thereof an aluminum or aluminum-alloy layer. The anodically oxidized layer (2) is formed on the surface thereof. The oxide insulating layer (3) is formed on the anodically oxidized layer (2) by the sol-gel method or by the organic acid salt thermal decomposition method. The insulated electric wire exhibits excellent heat-resistant insulating property and flexibility, and does not adsorb gases.
