ABSTRACT:
Electromagnetic parts have windings composed of an inorganic insulating cable including a metal sheath, an inorganic insulating material, and conductive wires. Thereby, the windings are adapted to have higher heat resisting properties by selectively employing a material having a higher melting point and not changing its state even at temperature of about several hundred degrees Celsius as the sheath and the conductive wire.
