Abstract

PURPOSE: To obtain a coil having superior insulation by winding the insulating tape of a polyparavanic acid film on an electrical conductor in piles wherein thermosetting varnish mixed a multifunctional isocyanate compound with the ratio of 2.5W25 in equivalent to a multifunctional epoxy compound of 1 in equivalent is immersed in the tape.
CONSTITUTION: A poly paravanic acid film is wound on the surface an electrical conductor in semipiles by several turns wherein the film is fixed by previously combininbg 2-ethyl-4-methylimidzole with polybutadiene with the ratio of 1g for a tape of 1m2 as curing catalyst. Next, glass fiber cloth attached a curing catalyst of 0.5g for a tape of 1m2 is wound by one turn on the extreme outer layer. Then, thermosetting varnish consisting of a multifunctional isocyanate compound of 2.5W 25 in equivalent to a multifunctional epoxy compound of 1 in equivalent is immersed in the tape after reducing pressure for heating cure. In this way, it becomes possible to obtain an electrical insulating coil having high insulation and corresponding to F familyWH family.
