Abstract
PURPOSE:To prevent the outflow of impregnated resin by making including a process of winding a glass mica tape or glass mica sheet to make it into a bundle of insulator, a process of installing plural coils on an iron core, and a process of heating hardening it. CONSTITUTION:Since heat-resistant insulated wires 1 are wound by several pieces by a glass mica tape 9, the heat-resistant wires 1 never contact directly with heat-resistant resin 8. Moreover, since the heat-resistant wires 1 and the glass mica tape 9 slide on each other, the elongation difference between the heat-resistant wire 1 and impregnated resin 11 by thermal expansion difference does not become the elongation in the longitudinal direction of the wire, and is absorbed between the heat-resistant insulated wire 1 and the glass mica tape 9 as the expansion in the diametral direction of a conductor flux.

図Stators for rotating electric machines such as electric motors used in places where the ambient temperature exceeds 250°C or 300"C, such as the tapping area of a blast furnace in a steelworks, the conveyance path for slabs, etc. in a steelworks, and the vicinity of a reaction furnace in the chemical industry. In windings, armature windings, etc., it is required to construct the windings using heat-resistant insulating materials that can withstand the above ambient temperature for a long period of time, and
There is a need for a winding wire and its insulating structure that have excellent environmental resistance and whose withstand voltage and insulation resistance do not decrease due to contamination of the winding wire by moisture, corrosive gas, conductive dust, etc. Figure 3
