摘要： A compound mica sheet is prepared by bonding a mica sheet to a woven fabric through a powdered epoxy resin with curing agent. The mica sheet holds a cured thermosetting resin composition impregnated therein and has an uncured epoxy resin composition including a curing agent impregnated therein. When thermosetting resin is forcedly impregnated, through vacuum/pressure impregnation, into a coil wound with the compound mica sheet which is adapted for use in medium and high voltage electric apparatus, and then cured, an excellent insulated coil is obtained.

摘要： An electrically insulated coil is composed of a coil and a mica tape containing a first resinous composition, wound upon the coil; the resinous composition containing a maleimide compound, an epoxy resin, a curing catalyst consisting of an aluminum compound, and a curing accelerator selected from the group consisting of a silane compound having a hydroxyl group and a polysiloxane compound having a hydroxyl group; the curing catalyst and the curing accelerator each being in an amount of about 0.0001 to 5% by weight based on the total amount of the maleimide compound and the epoxy resin; and the resinous composition being cured by heating after the mica tape is wound around the coil.The electrically insulated coil may further contain a second resinous composition comprising an epoxy resin and an acid anhydride, the second resinous composition impregnating the mica tape after the mica tape is wound around the coil, and being heat-cured together with the first resinous composition.
